amp power & driver sensitivity in multiamp setup
Hi Al- got it. I really don't think so, although it would help the amplifier to have lower distortion. He would still need either greater power or a more efficient driver. 
How important is the amp?
He insisted that it was the preamp & that I would surprised it was the preamp hence his design effort to minimize the distortion from it.Well if we are going to talk about distortion and coloration, preamps make very little of it, often a 1/10... 
Tube Watts vs. Solid State Watts - Any credence?
Tube amps using ultra-linear mode of operation use a lot of global negative feedback to generate a higher wattage.Bombaywalla, taken either in or out of context its hard to take this comment seriously. I've modified many Dyna ST-70s where the only... 
amp power & driver sensitivity in multiamp setup
Something that is missed from this conversation:The driver is measured in sensitivity, not efficiency. As a result the impedance must be taken into account; in this case it results in the efficiency being not quite so high. You can't exchange the ... 
Tube Watts vs. Solid State Watts - Any credence?
The effect has to do with the distortion of the amplifier.Since a transistor amp clips harshly, its obvious when it happens. A tube amp has a soft clipping characteristic (which can be modified somewhat depending on how feedback is used with the a... 
Otari or Technics Reel-to-Reel ?
You can find a lot of blank tape on ebay. Seems to me ATR is very much in production- a lot of studios are still using analog tape, enough to keep tape manufacturers alive. 
How important is the amp?
The amp is pretty important, but a lot depends on your speakers. If the speakers are meant to be driven with transistors, its likely you will not hear a lot of difference between amps. But if the speakers are meant to be driven with tube amps, you... 
Vintage tube amp resurrection with Variac?
There is a simple way to do this using an incandescent light bulb. You remove all tubes and put the light bulb in series with the AC power and turn it on.The light bulb will light up, which means most of the power is being dissipated by the bulb b... 
"Pressing Vinyl"
In this town, for the last 15 years if you were really arrived as a band, you put out vinyl rather than a CD. Its that way in a lot of bigger metro areas these days. Kids drive the market, not us fuddy-duddies :) 
Any thoughts on passive v. active speakers?
BTW, doing 20hz is not always the most important criteria IMO, for that matter many loudspeakers do that. Agreed, but as a manufacturer with a need for a reference, while that is not the most important criteria, its not acceptable if the bandwidth... 
Tubes and their problems
Power pentodes just don't seem to last as long as triodes, in a nutshell. 
Is no preamp really better that a good preamp?
How in g**s name can a active preamp give you more REAL detail (not perceived detail because of distortions) from the source than the same well match direct source to poweramp.??Please produce some laws of electronics in your answer and not voodoo... 
"Pressing Vinyl"
Saki70, there is still analog tape in production and there are still studios with analog tape. All three of our LPs that my band has made were recorded analog and the master tapes were used to make the LP.Whart, I think it would be risky to assume... 
Any thoughts on passive v. active speakers?
I've yet to see an active speaker do what mine do. Which is to say my speakers go down to 20Hz and yet are very easy to drive (98 db 1 watt/1 meter) and are very detailed (employing field coil drivers, which are to the dynamic cone world what ESLs... 
Tubes and their problems
@Bifwynn, we don't have a recommended set of hours on the tubes we use. FWIW power triodes are often good for about 10,000 hours owing to their simplicity. Octal base signal triodes can often do that as well. We've been warranting our tubes for a ...
