 This is a high quality 

desktop headphone amplifier

based on the popular CMoy amp design. 

NEW Desktop HiFi M2 amp!

New Desktop HiFi M2 headphone amp, compared to my portable amp, are increased sound quality and options due to :

No capacitors in signal path

2 x gold-plated RCA input jacks

Large 6.3mm phone jack



Powered from external PS, 5.5/2.5mm jack

12V-30V DC power supply required (not included)

Aluminum Hammond enclosure

natural anodized and black anodized avilable


                Desktop M2 headamp is built on a professional Printed Circuit Board (PCB) designed by me employing
                principles used in HI-END audio.
                All audiophile-grade parts are carefully selected for the best possible sound quality
                through long experiments and listening sessions.
                The amp is hand built and tested by me, Zigis, in Latvia and shipped worldwide.



Desktop HiFi M2 amp can greatly improve
the sound quality of your headphones
and boost the weak output of :


       Home Hi Fi stereo
                Hi-Fi amps and receivers' headphone out is only a mid-fi option. A Desktop M2 amp, connected to the line out
                of your home Hi-Fi, will out-perform the headphone out in any amp or receiver up to $2000.


PC, laptop soundcards 
                The headphone output from your computer’s built-in soundcard is weak and low quality,
               because of PC power supply noises. Use a headamp with your soundcard’s line out.
                                                      


       CD players, MP3 players
                 CD and MP3 players' headphone output is medium quality and weak, because of the low 
                 battery voltage and manufacturers' ambition to increase battery life.
               
             Easily drive headphones from 16ohm to 300ohm
                Desktop M2 headamp can easily drive any headphones and earphones with impedances
                from 16ohm to 300ohm, from Grado to Sennheiser HD-650.

Parts and technology used in Desktop Hi Fi M2 amp


   
       Burr-Brown Texas Instruments OPA2134 dual op-amp

                One of the best FET input op-amps in audio, suitable for battery
                use. Made by Burr-Brown Texas Instruments.

       Gold-plated 8-pin DIP socket

                You can easily change op-amp to any dual DIP-8 op-amp

       Gold-plated RCA input sockets

       Large, 6.3mm headphones socket

       5.5/2.5mm DC input socket, for external 12V-30V PS (not included)


       Professional PCB
                 Desktop M2 headamp is built on a professional Printed Circuit Board (PCB) designed by me employing
                 principles used in HI-END audio, such as the shortest possible signal path and power supply caps
                 as close as possible to the op-amp power leads. All parts, including volume pot and jacks,
                 are on PCB without any wire and cable. 

       ALPS RK097 volume control with power switch
                The volume control is a high-quality Japanese ALPS RK097 potentiometer with built-in power switch.
                The ALPS pot's channels are perfectly matched , ultra smooth and quiet-operating,

       Metal film 1% + hand matched resistors
                 All resistors are highest quality metal film 1% tolerance and hand matched by me to ensure
                 both channels are identically balanced.

        
       TLE2426 Rail splitter
                To allow amp work from external 12V-30V DC PS, the power supply uses
                a high performance TLE2426 voltage rail splitter which provides
                precisely balanced positive and negative supply voltages.

       2 x Panasonic FM low ESR 470 mf power caps

                Japanese made Panasonic FM capacitors with ultra low ESR which have a faster discharge rate.
                This results in the clear, detailed highs and low, deep bass.
