Big, big room -- which 10-20k speakers?
Almarg makes good sense as usual :)The larger Tannoys are another good possibility. 
Rolling Tubes in the Atma-Sphere C-30 amp
In the S-30, the rear tube has a little more voltage on it. If you are using NOS tubes, a -GTA or -GTB is recommended. A GT will also work but will not last as long- it is running right at its limits. So save your expensive KenRads or whatever for... 
Are Monoblocks better than Multi-channeled amps??
An excellent example of this is the old Dynaco Stereo 70, a venerable 35 watt tube amp. Dynaco made something called the Mark IV, which was the exact same parts and construction except for the power transformer (which was a little smaller than the... 
cathode-follower tube preamps..
If you have a direct-coupled output on the preamp the output impedance will not vary with frequency (with most tube preamps its usually the bass where this is an issue). If you have a 10:1 ratio at 1000Hz but only 5:1 at 20Hz, you will hear that a... 
Best Amp for Klipsch La Scala Speakers? Xmas Gift
200 watts on a LaScala?? Most of our customers use either the S-30 or M-60. Unless you have a huge room 15 watts is going to do a lot on this speaker. 
Big, big room -- which 10-20k speakers?
The Classic speakers don't have the resolution.This is a load of bull. The Classic Audio keeps up with any of them. Its beryllium midrange field-coil driver is very fast, relaxed and revealing. The speaker uses Mundorf caps in the crossover with 6... 
A phono amp that beats the MFA Magus's phono?
Some of the Magus preamps had a step in the EQ curve (at 50KHz) that results in the phono sounding bright. Its easy to fix it as it involves removal of a couple of EQ parts. 
cathode-follower tube preamps..
If you are trying to drive an amp with a low input impedance, and you want tubes then you will need one that has a cathode-follower or Mu-follower output.However the amp has a balanced input so you might consider tube preamps that are balanced as ... 
Best Amp for Klipsch La Scala Speakers? Xmas Gift
The speaker is tube friendly and good efficiency but does benefit from some power.If you can find a use Atma-Sphere S-30 that might be within the budget. But any tube amp in good shape will be a player on this speaker. I would avoid transistors un... 
Jm Lab Alto Utopia what kind of amplifier ?
Our customers report good results so I think its safe to say that the JM Labs speakers do well with tubes. 
Can I replace a 24uF capacitor with 22uF?
Grannyring, you should give it a shot.Electrolytics got a bad name because so many designers don't know how to use them. If they are set up properly they can rival film caps quite easily. If not- then they suck. 
Big, big room -- which 10-20k speakers?
This is a second recommendation for the Classic Audio Loudspeaker. You will want the efficiency!If that is outside of your budget the Dreammaker by Audiokinesis is another possibility- it is relatively efficient too. The other speakers in your lis... 
$18k Tube preamp for large scale symphonies please
If you are listening to a multi-track recording, the effect is not audible. It really has to be a true stereo recording to show up. 
Direct drive vs belt vs rim vs idler arm
Whatever the table, it should have a robust drive. If you look at the vintage machines that have really garnered a following, you will see that they all have that in common: the SP-10, the Garrard 301, the Empire 208, the Lenco...Wimpy drives seem... 
Can I replace a 24uF capacitor with 22uF?
You can make electrolytics work but they have to be biased correctly! I don't know why, but for some reason most speaker manufacturers don't do this. The problem is that electrolytics can't be reverse-biased. This is supposed to be why you use non...
