Amplifier hum - normal?
I'm with Studio68.Why not try the PS Audio Humbuster or the Channel Islands XCD-2, whichever is available with a home trial.At least that way you'll determine if DC is the cause of the hum before you go messing around building a DIY DC blocker tha... 
Seeking advice on tube amps
03-13-09: Jmcgrogan2...he sounds like he is in the push-pull tube land. There really are very few speakers that some tube amp cannot drive. I disagree.Driving speakers is more than an issue of plenty of power. It's also an issue of balanced freque... 
Seeking advice on tube amps
Nsgarch, your point is well taken. Let me make my recommendation more clearly than I have done thus far in this thread.I suggest finding some tube friendly speakers first (90+ dB sensitivity, 8 ohm nominal impedance with dips no lower than 6 ohms)... 
Silverline Sonata III & McIntosh MC275?
The conclusion I reached was that for someone on a budget those stacked Minuets and a good sub woofer would be a great combo for someone on a budget...Newbee (System | Reviews | Threads | Answers)I absolutely agree. The Minuets were quite impressi... 
Pass Labs xa - .5 amps
It's also good to know the single ended connections are not any different then the balanced if I keep my CJ Act 2. Thanks Tvad.. Mozvz (Answers)Just to be clear for those who might not read every post in the thread, I did not state that the single... 
Tube Amp for Green Mountain Audio Callisto
Do you have a decibel meter (like a Radio Shack)?If you do, turn up the volume to your normal listening level at the listening position, then measure the decibel level from a distance of 1 meter directly in front of each speaker (left then right, ... 
Pass Labs xa - .5 amps
I've run balanced and single ended into my XA-60.5 from the same preamp, and I've noticed minimal difference. 
How to reduce power supply noise.
Are you asking this with the intention of doing some modifications yourself, or are you asking with the intention of purchasing a modification?That's why I asked this question earlier. Had I known you were intending to DIY, I wouldn't have linked ... 
Anyone know how good MHDT Labs Paradisea DAC is?
Samzx12, what is the input impedance of the preamp or integrated amp you were using with the Paradisea?An impedance mismatch between a high output impedance device and a low input impedance device can result in weak bass, and roll-off at the extre...

03-12-09: LithojoeI've had the best tube amps made years ago.What were those? 
Heed Quasar Outputs
Well, as I say, I use a .25mV cart, and gain is not an issue whatsoever. 
high voltage's affect on amplifier performance
+/- 10% voltage swings from a transformer's voltage rating can cause transformer hum. 
Seeking advice on tube amps
Exceptions. Absolutely.I think the successful exceptions are usually accomplished by people who have done a good amount experimentation and listening, or by people who are well educated in component matching.Having gone about it backasswards mysel... 
Heed Quasar Outputs
The MC section works best with cartridges in the 0.6mV - 1.25 mV range (despite the published sensitivity ratings). High output MC cartridges work well on the MM section, but low output MC cartidges require a little more gain than what the Quasar ...
