Looking to Try a Passive Preamp
I own the Jolida Glass FX DAC III and I was curious about the 47K output impedance figure because my preamp lists 13K as the input impedance and the audio sounds OK. Well, I just called Jolida and they said that the actual output impedance is 600 ... 
Conrad-Johnson Discolored (rusty?) Allen screws on side of MF-2550.
I'd be inclined to just get a bunch of rustproof screws and replace them but I want to first find out if they have to be a specific kind of metal and what they are fastened to. I'd hate to mess up the job of re-fastening new screws to components i...

Problem with Thorens TD-203 speed adjustment screws
Since writing that two years ago I got my TD 203 turntable back from the shop long ago. It was still a little off so I gave it another try, turning the screws as gently as I could. The main problem was that each tiny turn made a relatively big cha... 
Azimuth setting using channel decibel level on a mono LP?
I asked the same question in another forum and got the answer that channel balance and azimuth are not the same thing because a perfectly centered stylus at its exact azimuth can still have some voltage differences in the two channels, causing per... 
Thorens TD-203 experiences?
I recently ran into a little snag with my TD-203. I noticed that digitized audio always was always a bit faster (shorter length) than the posted times on the LP cover. An app showed that the RPM was 33.9 instead of 33.3. Next, I tried to adjust th... 
Problem with Thorens TD-203 speed adjustment screws
I read that the trick with those apps is to place an object around the spindle (like a roll of tape or plastic cup) and center the phone on that. When I did that I got a constant 33.9, but when I just laid it on the platter I was getting different... 
Problem with Thorens TD-203 speed adjustment screws
Actually, they were very nice and said that they'd order a new factory motor and I would not have to pay. It would be covered under the warranty. I told them the truth that I really don't know if it was damaged to start with or if I caused it. I d... 
Thorens TD-203 experiences?
I just bought one as a replacement for an original Pro-ject 1. The TD-203 at its new lowered price of $699 and an Ortogon 2m Blue looked like the best bargain out there. I first was unsure of whether there was a VTA adjustment, but I found out tha... 
Thorens Turntables
I just bought a new Thorens table (PD-203). The price was reduced a lot (to US $699) and the lower quality cartridge it comes with was replaced by the Ortogon 2M Blue. The cart may not be broken in yet and sounds a little too strong in the treble ... 
Power Amp Repair Question
Sure. It's Hi-Fi Heaven in Falls Church, VA.I already moved on and placed an order for a brand new amp. I got a nice trade-in on the working McCormack that I have left. It's not worth the hassle to struggle with getting the broken amp back. My new... 
Power Amp Repair Question
I eventually called and asked for a date certain about when I would get an estimate. Note that they did not call me. The owner said that he does have the estimate and that it's $600, far above what I think is reasonable. He gave no details at all ...
