The output of the DirectStream DAC is transformer coupled, and in that sense can loosely be considered to be passive, but unlike resistive-based passive preamps it has an output impedance that is low enough to be comparable to that of most active ... 
External Drive Help
P.S. to my previous post: To be sure it's clear, when I said that "I agree with Michael's comments re Western Digital," I was agreeing with Michael/Sufentanil's statement that he "disagrees with the blanket statement that WD are unreliable."I've u... 
External Drive Help
I agree with Michael's comments re Western Digital, and about the inevitability of drive failure. I would put it that backup strategies should be based on the assumption that any drive can fail at any time.Regarding online backups, though, a point...

03-09-15: Ricred1Speakers are as follows:the rear of the speakers are 4' 2" from the front wall8' apart, 4' 8" from sidewalls, I sit 10'away, my head is 6'away from the rear wallI have 2 GIK Soffit Bass traps in each front corner from floor to cei...

Ricred, what can often be a very major contributor to lack of bass impact is the acoustic effect of the rear wall (the wall behind the listening position). I can't tell from your system description photos what that distance is, but under typical i... 
USB cable hype
03-09-15: AxleMy question wasn't about the cable's effects on SQ. It was about failure: At what distance does a vanilla USB cable start to fail? I'm sure the answer varies with drivers and date rate. For example, we know that PCM should travel far... 
Amp and preamp on same outlet?
John & Jim, ROTFLOL!! Thanks!!Best regards,-- Al 
Balanced/Unbalanced question
ZD, my speculation would be that the center pin of the RCA input connector on each channel of your Ayre amp is electrically connected to pin 2 of the XLR connector (the non-inverted signal pin on the XLR connector), and is processed through the sa...

Hi Dan (Islandmandan),I found this impedance curve for the HPD 315he, which confirms (as might be expected for a Tannoy) that its impedance characteristics are very benign. (If the link just opens at flickr.com instead of opening at the specific p... 
Proac problem: tweeters or crossover?
Regarding my suggestion of a test record or CD providing 1/3 octave warble tones, Stereophile's Test CD 3 appears to be suitable (specifically tracks 17, 18, and 19), and is available here. Further description is provided here.A possible limitatio...

I'm not familiar with the specific amp, but in general I would not expect a bridged amp to provide good results when driving your particular speakers. As can be seen in the impedance curve shown here, the impedance of your speakers is in the vicin... 
Proac problem: tweeters or crossover?
Twoleftears, as you may be aware tube amplifiers having output transformers should not be operated without a speaker or equivalent load being connected, especially when signals are being put through them. Assuming you are still using the Cary SET ... 
What companies, out of Business, did you LOVE???
P.S. to my previous post: To clarify, the 1951 prices I mentioned were per monoblock.Best regards,-- Al 
What companies, out of Business, did you LOVE???
Yes, that's right Larry. As far as I am aware Brook was the only manufacturer (or at least the only USA manufacturer) of directly heated triode audio amplifiers intended for use in the home (the Western Electric/Northern Electric products being th... 
Amp and preamp on same outlet?
If Al is still following this thread he can do a better job of translating the info from page 22 of the owner manual than me.Hi Jim,I can't do that with any certainty, because as I see it the specs provided in the manual are both ambiguous and inc...
