Preamplifier: Yes or NO ?

Another "yes" here as well.

I have not gotten good results without preamps even though I had an Audio Aero DAC with built in preamp and vol control, and with a vol control on my current cdp. There was always "something" missing.

NO--in my system I only have one source, an Audio Aero Capatole mk2. I tried it with my BAT VK50se and without. I sold the BAT and bought some nice IC's. In my system, and to my ears it clearly sounds better going direct!!! You will have to try it for yourself in your room with your system. There is no right or wrong.

FWIW. Bought a Wadia 302 and connected it to my preamps(s) as per the conventional wisdom and the reviews recommendations as well. Yawn!

Connected direct to 4 different amps, 3 tubed, one SS = 1 ok, 2 duds, and one with outstanding results and I now have the best sound I've ever had and without a pre-amp. Pays to keep and open mind and experiment if you can!

preamps can add some "solor" to the sound. given the dubious sound quality of most cds and some lps, a preamp, especially a vintage tube specimen, is necessary to avoid ear fatigue.

Mrtennis: What is "solor?" Regardless, you offer no proof -- just your opinion, which, given your stated preferences, isn't worth a great deal to many of us in Audiogon Land.

I have found that a Wadia 861 SE with the Great Northern Sound Company Reference mod run directly to my ARC VT100MKIII sounds pretty darn good with no "ear fatigue" whatsoever. It's crucial, though, to set the internal switches correctly so that the majority of your listening is done in the 70-100 volume range. A lot of people don't do that and conclude that it doesn't sound good. That is hardly the proper way to make an evaluation.

Oh, I tried several high-end preamps, including ones from Audio Research and Pass, and thought the Wadia sounded better IN MY SYSTEM without the preamp.
