MHA150
2-Channel Headphone Amplifier
Highly
Recommended
The MHA150 Headphone Amplifier is a worthy successor to the critically-acclaimed MHA100. The MHA150 contains the same feature set and performance standards but adds our new 2nd generation digital-to-analog converter (DAC) that provides support for DSD and DXD files to give you access to the latest in digital music.
Like the MHA100, the MHA150 continues to take advantage of unique McIntosh technologies to create the best possible personal listening experience regardless of the headphones you use. Our Autoformer™ technology found in our large mono and stereo amplifiers has been adapted to produce three headphone impedance ranges of 8-40, 40-150 and 150-600 Ohms so that every headphone will receive the legendary McIntosh sound quality and performance.
For enjoying DSD and DXD files, the USB input accepts PCM signals up to 32-bit/384kHz and supports DSD64, DSD128 and DSD256 along with DXD 352.8kHz and DXD 384kHz. Our proprietary MCT input has also been added to the MHA150; when paired with the MCT80 SACD/CD Transport, it offers a secure DSD connection for playback of the high definition audio on SACDs.
For connecting digital devices, an optical and coaxial input are included along with the USB and MCT inputs; two analog inputs are also available. Headphone Crossfeed Director (HXD®) brings added dimension to your music in a natural sounding way but can be turned off depending on your preferences. The MHA150 is smaller than our other amplifiers, giving you additional flexibility to locate it almost anywhere in your space. It’s the same width as the MB50 Streaming Audio Player and the two can be combined to start building a complete system.
The MHA150 is powerful and versatile enough to drive a pair of quality desktop or small bookshelf speakers via its 50 Watt stereo speaker outputs. Our patented Power Guard® technology is included and will prevent clipping that could damage your headphones or speakers. A 5 step Bass Boost Control allows for further sound customization. It is one of many McIntosh products to receive Roon Tested designation from Roon Labs. It has been profiled and tested by both Roon and McIntosh for maximum compatibility. Roon will recognize it and send it audio optimized for its capabilities. No fiddling with checkboxes or dropdowns, Roon Tested devices are automatically identified and configured out of the box for a superior customer experience.
The entire unit is housed in a beautiful polished stainless steel chassis that not only compliments the classic glass front panel, knobs and brushed aluminum end caps, but virtually any room decor. Contact your local dealer to learn more.

Thank you for contacting McIntosh Laboratory, Inc. We will reply to your message as soon as possible.
Welcome to the family of McIntosh owners. This is the Warranty for your new McIntosh Home Electronic Product (the “Product”). Your Product has been designed to give many years of trouble-free performance. Nonetheless, failures do sometimes occur even with equipment as well-built as McIntosh’s. Therefore, please read this Warranty carefully, because it contains rights, as well as limitations, exclusions, and obligations, which in the event of such a failure may be very important to you. If after reading it thoroughly, you have any questions about the Warranty, please do not hesitate to write or telephone McIntosh at the address or phone number shown on the back of this warranty. Please note that this is the only Warranty which McIntosh provides for your Product, and that no one, including your dealer, has any authority to either modify or expand upon this Warranty. If your dealer has offered or made any warranties or representations concerning the Product which differ from those contained in this Warranty, they are strictly between you and the dealer, and will neither be binding upon McIntosh nor change any of the provisions in this Warranty. Please also note, that if your Product ever does require Warranty service, obtaining such service will be much easier if you have completed and returned the enclosed Warranty Registration Card. So please take a minute to fill out and return the Registration Card now, before you become too distracted by the great sounds coming from your new McIntosh Product!
Scope and Duration of Warranty
Subject to the terms and conditions stated below, McIntosh Laboratory, Inc. (“McIntosh”) warrants to the original owner that this Product shall be free from defects in workmanship or materials for a term of three (3) years from the date when it was purchased from an Authorized McIntosh Dealer. Provided, however, that rather than the three (3) years of coverage afforded the Product generally, where applicable, vacuum tubes contained in our Products are warranted for 90 days from the date of purchase, hard disc drives and projector lamps contained in our Products are warranted for one (1) year from the date of purchase.
Limitations on Persons and Products Covered by this Warranty
This Warranty and all rights provided here under are limited to the original owner. In the event that the original owner transfers ownership of the Product prior to expiration of the three-(3) year term, this Warranty shall terminate in its entirety upon the date of such transfer. In addition, McIntosh does not warrant in any way Products which are purchased from anyone who is not an Authorized McIntosh Dealer, or which have had their Serial Numbers altered or defaced. Therefore this Warranty is void and inapplicable if this Product has been purchased from someone other than an Authorized McIntosh Dealer, or has had its original Serial Numbers altered or defaced.
Geographical Limitations
McIntosh directly warrants all Products which are purchased in the United States or Canada, and Warranty only applies while such Products are used in the United States or Canada. Products purchased outside the United States or Canada, used outside the United States or Canada, and failures occurring outside the United States or Canada, are covered under separate warranty terms as determined by the Authorized McIntosh Distributor in the applicable country. Questions regarding the availability and scope of warranty coverage in such situations should be directed to the Authorized McIntosh Distributor in the applicable country.
Limitations on Third Party Services and Data Sources
Certain McIntosh Products include an interface that enables access to services (including data) that are provided by third parties unrelated to McIntosh (such as, by way of example only, Amazon Cloud, Spotify, Gracenote, etc.). Some of these services require separate customer subscriptions and some do not; and some may be supported by and compatible with the McIntosh Product while others may not. Merely providing the capability to access such services is not to be construed as making McIntosh the provider of, or responsible for, the services, or for continuing to support or make such access available; and McIntosh expressly disclaims any such responsibility. Because McIntosh cannot control the providers of such services or the services themselves, and similarly cannot control the communication systems and networks that connect the Products’ interfaces to the services, McIntosh cannot and does not warrant against, and shall have no liability of any kind for, any of the following that are related to third party services, the providers of those services, or the systems or networks by which the McIntosh Product communicates with the services: (i) unavailability, lack of compatibility or functionality, interruption, discontinuance, or loss of service, or other unsatisfactory performance, act, or omission; (ii) loss or unauthorized use or disclosure of, or damage to, personal information, recordings, or other data; (iii) reduced functionality of the McIntosh Product; or (iv) any other loss or damage of any kind. McIntosh likewise does not warrant against, and shall have no liability for, any failure of its Products to satisfactorily process any externally sourced data where such failure is attributable in whole or in part to the makeup of the data itself or to a non-McIntosh product, system, or service that is the source of the data or that provides access to the data.
What McIntosh will do under the Warranty
In the event of any defect covered by this Warranty, McIntosh shall without charge provide all parts, materials, and labor necessary to restore the Product to its original specifications. After repair, McIntosh shall return the Product to its owner at the owner’s expense. In the alternative, McIntosh may at its sole option either replace the Product without charge, or if replacement is not commercially practicable or repair or replacement cannot be accomplished within a reasonable time, McIntosh may refund the purchase price of the Product, subject where appropriate to reasonable depreciation for actual use in accordance with applicable laws, in full satisfaction of its warranty obligations. McIntosh or its Authorized Service Agency will undertake to complete the repair and return of the Product as soon as circumstances permit, unless prevented by causes beyond their reasonable control.
Limitations on McIntosh’s Obligations under the Warranty
McIntosh’s sole Obligation under this Warranty shall be to repair or replace the Product, or at its option refund the purchase price, as provided for hereinabove. McIntosh does not warrant against, nor shall it be liable for, any of the following: removal or installation charges; shipping expenses either to or from McIntosh or its Authorized Service Agency; loss of use; property damage of any kind; or other incidental or consequential damages or losses of any kind.
Note: Some states do not allow exclusion or limitation of consequential damages, so the foregoing exclusions may not apply to you.
Parts and Occurrences that are not Covered by the Warranty
This Warranty does not cover any of the following: (a) glass panels, cabinetry, trim, or other appearance items (except where they are defective at the time of original sale and the Product is delivered for repair within the first thirty (30) days thereafter); (b) batteries, or damage to the Product caused by failure of batteries; (c) or damage to the Product caused by failure of projector lamp; (d) loss of, or damage or corruption to, digital data, files, or other information content of any kind, regardless of cause; (e) failures arising from accident, catastrophe, misuse, neglect, or failure to properly connect and operate the Product in accordance with the accompanying instructions; (f) failures arising from improper installation or removal of the Product; or (g) failures arising from any tampering, alteration, or damage to the Product or attempted servicing of the Product by anyone other than McIntosh or an Authorized McIntosh Service Agency; and McIntosh shall have no liability or obligation of any kind with respect to any of the foregoing types of failures.
What the Owner must do to obtain service under this Warranty
To obtain service under this Warranty, the owner must at the owner’s expense arrange for any necessary de-installation of the Product, and deliver or ship the Product to McIntosh at the address below, or to an Authorized McIntosh Service Agency, properly packaged, prepaid, and insured at the owner’s expense. In addition, the owner must provide evidence that the Product is at the time of delivery within the scope of his Warranty, by either having completed and submitted to McIntosh on a timely basis the accompanying Warranty Registration Card, or by including the original sales receipt (photocopies are not acceptable) with the Product when it is delivered for repair.
What the Owner must Pay For
As noted above, the owner must pay any expense of removing the Product from its installation, and must pay any expenses for delivery of the Product to McIntosh or the Authorized McIntosh Service Agency. Upon return of the Product to the owner following repair, it shall be the owner’s responsibility to pay for the shipping charges incurred in return of the Product, as well as to arrange and pay for any re-installation which may be required. In addition, it shall be the owner’s obligation to pay for any repairs made to any Product for which the owner has neither completed and submitted the Warranty Registration Card at the time of purchase nor included the original sales receipt with the Product when delivered for service, at McIntosh’s or its Authorized Service Agency’s then-current repair rates.

This is one of a limited number of McIntosh products that MAY BE SOLD AS NEW ONLINE OR BY MAIL OR PHONE, solely by specifically authorized online McIntosh dealers located in the United States, solely to and for delivery to, purchasers living in the United States.
(i) Sale or delivery of these products outside the United States, (ii) Purchase from an unauthorized seller, or (iii) Purchase of a used unit, will void the manufacturer’s warranty.
