Buffered or unbuffered volume control, and if buffered, what circuitry is forming the buffer for the amplifier?
digital or analog volume control?
I am presently running my dac direct to my amplifiers using the digital volume control of foobar (for ripped cds) and MPCHC (for movies). When I play movies on MPC it indicates playback at 32 bit floating point, and from what I have read, Foobar does the same, and both sound great to me. I am having a dac modified (Monarchy audio M24) and my tech has given me the option of direct out (like I am using now - with no analog volume control) or either an alps or ldr type volume control - at added expense, the latter the most expensive. Is the analog volume control better sounding than the digital that am presently using?

There is controversy in this industrial as to whether a digital volume is just as good as analog volume control. At 32 bits, most engineers say it doesn't matter. I have always been of the opinion that digital volume can be compromise, especially at low listening levels. That being said, adding an analog volume control to your output could affect the output impedance driving the amplifier. You are, essentially, placing a "passive preamp" between the DAC and the amp. |
If you decide to go with an ALPS have your tech check out this... https://www.partsconnexion.com/ANVPOT-81914.html Only available in 100K Ohm though, as far as I know. DeKay |
