Favorite moment with music in your car.
In the late 70s I was driving north from Baltimore to New Jersey listening to a decades long folk music show from Philadelphia, Folklore, emceed by Gene Shay. He played a song sung by Priscilla Herdman, who had an utterly gorgeous , angelic voice,... 
Thoughts? - First Watt F8 / Vandersteen Treo's
Vandersteen calls the Treo a 6 ohm load. Unlike most solid state amps which have more wattage into lower impedance loads the F8 reduces power  into lower impedances putting out 1/2 power into 4 ohms so the 6 ohm output is probably midpoint or abou... 
VPI Scoutmaster to HRX
Why the HRX? It's long been out of production. I'd look at some of the current VPI tables. A version of the Classic 3 is being produced and that seems like a good table to look into.  
Worst Speakers Ever??
Hi again bdp24. It turns out one of the speakers we also had at Wall to Wall Sound was the original ESS Heil speakers. They were ok(small letters). And we had one set of vinyl Dynaco A25 speakers on sale for $52/pair(They were just there for bait ... 
Worst Speakers Ever??
In the 1970s I was friends with Gordon Holt and helped him with Stereophile. bdp24 reminded me that Gordon was throwing out a set of ESS Transtatic Ones. He was late reviewing them and ESS didn't want them back because they had gone onto the Heil ... 
Worst Speakers Ever??
In the mid 70s I worked for a Philadelphia area chain called Wall to Wall Sound. I could tell you stories about them but I'll stick to one speaker sale. I was selling a decent receiver with a set of speakers. We had 2 levels of house brand speaker... 
FAKE NEWS - NEGATIVE REVIEWS NOT ALLOWED!!
If an exhibit room sounds good it is. But if it sounds bad you don't know why. Is it the setup. Is it brand new gear that needs breaking in? I could go on. If you don't know why then negative comments hurt the equipment and you really don't know w... 
Halcro update
This is a comment on Lynn Olson's comment. Decades ago I had a demo by David Berning and Murray Zelligman at CES 1979 of the Audionics BA150 amp designed by David Berning. The amp had variable negative feed back from 16 dB to 0 dB, As the feedback... 
Leaving my amplifier on ok?
In general for tube amps it's better to turn them off. With one exception that I know. David Berning's amps. David designs for long life, very, very long life in total contrast to almost every other tube designer. I know from a friend who was ther... 
Tube Preamp: How many tubes does it take to .................
I'll throw in another possibility for 'extra' tubes in a preamp that can improve fidelity, cathode followers after again tube. They supply a nicer impedance match to the next gain stage. If every gain stage in a preamp used them you end up doublin... 
Best EXTERNAL DAC suggestions
Mike Moffit, the Schiit digital designer is one of the greats. He's been at the top of his field for over 4 decades.  
Perplexed on how single driver speakers can cover such a large Hz range
Speakers don't exactly create different frequencies and then put them together. The single signal is a complex combination created by a signal composed of all the frequencies a microphone picks up. The signal is a complex of hills and valleys one ... 
Perplexed on how single driver speakers can cover such a large Hz range
An interesting oldie from the 70s was the Rectilinear X(ten) 3 way but the mid range ran from 200 Hz to 8 kHz with a 2 " cone tweeter above that and a 10" woofer in a closed box below so an almost full range speaker. And interestingly the crossove... 
What speaker could safely be ordered without hearing it first?
None no matter how revered they are even by every expert. No speaker is perfect and the combination of characteristics that make you happy may be very personal. Saying that there may be two ways to do it. The safest is, of course, if you can retu... 
A Black Box to Solve Everything
It isn't as simple as adding higher tube distortion. The Carver concept of transfer function actually works though, to  signmake a solid state amp sound like a matching tube amp, which is exactlly matching the electrical output of two amps. But I ...
