Amp and preamp on same outlet?
Tim (Mitch2), this post by Atmasphere dated 6-3-14 is one of those in which he has explained the brief high current spikes which characterize the majority of the current draw of most power amplifiers, as Jim (Jea48) indicated above.To put things i... 
Anything as " fast" as SPECTRAL gear?
JJ's doesn't have any locations in my area. But before playing a recording that might call for a sub (which doesn't happen too frequently with my speakers), I can always drive over to a Subway location if need be. :-)Best regards,-- Al 
Anything as " fast" as SPECTRAL gear?
Bombaywalla, thanks for the additional thoughts. However, while I agree with your math, I don't completely agree with the conclusions you reached. As I'm sure you recognize, my hypothetical example involving 200 watts at 200 kHz, as well as the fi... 
Importance of Amplifier versus Preamp?
As Mr Carver demonstrated, by building an affordable amplifier, of which the sound could not be distinguished from an extremely expensive name amplifier that was being compared to (mid`s 70)!To clarify some points about that:What Carver did, actua...

Rebbi's small complaint was that the DeCapo did not capture the lower octave on stuff with Synth bass with his 300B.Rob, more precisely the complaint was that the amp clips when reproducing that and other material having high volume content at dee... 
vintage versus modern speakers
Seconding Larry's characteristically excellent post, there are reasons that Western Electric speaker drivers from the 1930's command astonishing prices these days. And it's not just rarity, although that is certainly a factor. Or that Tannoy speak... 
Motorboating after tube change
It happens to the best of us, Jim :-)I note that two of the absolute maximum ratings of the 5751 would most likely have been exceeded by a considerable margin as a result of inserting it into the 5755 socket. The absolute maximum negative grid bia... 
Motorboating after tube change
Jim, :-) I suspect that you looked at the tube datasheets either with an iPad or some such device having a very small screen, or without putting your glasses on :-)The two tube types have identical pinouts for their filaments (pins 4 and 5, with t... 
Amp and preamp on same outlet?
Thanks, Jim (Jea48). Excellent points, some of which are further emphasized and explained on pages 31 to 35 of this excellent paper, which you had called attention to a while back.Wrm, thanks also. Best regards,-- Al 
Amp and preamp on same outlet?
Using separate outlets, especially if they are on separate runs back to the breaker panel, will reduce the amount of amplifier-generated electrical noise that may couple back into the preamp. On the other hand, doing that may increase susceptibili...

Rebbi, note that the price of the Triumph Extreme II is indicated as being in Canadian dollars, while the price of the stands is indicated as being in US dollars. If those prices are accurate, at current exchange rates the total cost of both be $3... 
vintage versus modern speakers
I note that the OP indicated a budget of $1500. My suggestion is that he go to the Audiogon home page, click on "speakers" on the left side of the page, then click on "continue to all speakers listings" on the right side of the page, and then in t...

Regarding the possibility of adding a sub, in addition to the concerns about integration that have been raised I would have some concern that the high pass filter and other circuitry in the sub, that would be in the path between the preamp and the... 
Anything as " fast" as SPECTRAL gear?
Al; where the heck did you get this knowledge?I'm an EE with extensive analog and digital design experience (for defense electronics, not for audio), and I've been an audiophile for about 35 years. Audio has always been of interest to me from a te...
