Preamp for audio research ref110
Thank you all for the help. I think I will get an RCA to xlr converter until I get the real thing. Seems like these are available from pro-audio shops. Regarding the cart, I am using a simple shure m97xe 
Amp question for Maggies
I drive my 20.1s with the Conrad Johnson MF2500 (better than Ice Power which I also own). Its also excellent VFM. 
KEF LS50 Need Help
From your description of the sound you are looking for I recomend Vienna Acoustics. At the price range you mentioned you can get a pair of Mozart or used Bethoveen. 
Best Amp For Maggies 1.6 Tube Or SS
I own both 3.6s and 20.1s, after playing with a few amps my preferred amp is the Conrad Johnson MF2500. I think their smaller MF2250 Would be a good match as well. At their going price they are true bargain. 
An interesting experiment
Almarg,I completely agree with you. In fact when I thought of trying this, the effect you mentioned is exactly what I was looking for. clearly if one is looking of a high fidelity setup this is not the way to go. However, sometimes playing with th... 
An interesting experiment
to be clear, the I have a 10K POT for volume control followed by a series resistor (also a pot so I can adjust it). After thinking about it I realized that I made a mistake when saying that the amp is rated for 10K. Since each module operates in f... 
An interesting experiment
Yes, I am presently using a 10k passive pot for volume control (Incidentally I am using a Sescom mkp-25, which is only 50$). I also have at my disposal an ARC LS2 and the AI module 3a. But the pot arrangement sounds excellent to me. More like the ... 
Optimizing Digital Volume Control
Audioengr, I agree that the input impedance of a power amp is probably slightly frequency dependent, and hopefully not amplitude dependent. So I agree that a low impedance source is a good idea. My point is only in regards to how low is good enoug... 
Optimizing Digital Volume Control
Regarding preamp drive or DAC drive, the argument that the upstream component driving the amp should have a "low impedance with a lot of drive capability" while technically correct, in practice should be a non issue for any reasonable designed com... 
Optimizing Digital Volume Control
Let me qualify my comments by stating that my conclusions are a combination of about 6 months of listening and many years of engineering studies. I listen mostly to classical music, so this may be coloring my assessment. My speakers are Magnepan 3... 
Optimizing Digital Volume Control
Thank you. Just found the write up on this topic. Seems like they know what they are doing :-)BTW, this leads me to believe that a preamp is practically no longer required. The best reference preamps at best can match a good 2K DAC. So most likely... 
New tubes biasing problems
Thank you all. I did move the tube to a different socket and the problem moved with the tube. And I did re install one of the old ones and it all worked well. So I am now going to order another matched pair. BTW, is it safe to operate with 3 new t...
