Jim the auditioning is done in a relatively small room with hardwood floors (18ft by 15ft with 9ft ceilings) near field as to eliminate as much of the room as possible. I mentioned the connections used above (starting thread) as I will with the other dacs when they arrive. When I can used the same type of connection I will and with the same cable.
Components other than the dacs are my own design. Solid state amps 100 watts/channel and 2 way stand mount speakers. My larger sys consists of an active system which uses 6 channels of amplification and for this, I simply wanted to get at the soul of the device under test...very direct on level playing ground. The system I am using is very neutral...not thin, not cool, not warm... neutral.
I do now want this to go into gear-fest, it is specifically to see for myself (and I am sharing for those interested) a real consumers (i.e. non dealer, non pro reviewer... non silent investor) point of view on a lot of newly hyped gear. Hope this helps :)
I will tell you that I recently got rid of a Wadia 851, a Bat Rex and various other better known pieces. I sold my Manley Labs Neo 300's but I think I am going to buy that particular amp again, I used it on the tweets in my active system (with Princess Mesh plates...very NICE). I do prefer active systems over passive ANY DAY OF THE WEEK :) but the test system is all passive.
