What is the best transport?
Here is the other thread Dvavc refers to in his post above. The link opens at his initial post in that thread, which is followed by some interchanges between him and Steve N. of Empirical Audio, and some comments by me.Regards,-- Al 
Lossless Files Vs CD's
05-26-14: DvavcThe point here is that you loosing the quality of the sound (SQ) right there when you ripping/converting PCM files from CD in to WAV on your comp.FWIW, I see no technical basis for that contention (assuming the rip is done with soft... 
Speaker hum problem - need help
Question: In addition to the hum emanating from the speakers, is there ALSO a hum or buzz coming directly from the amplifier?Regards,-- Al 
biasing for 4 ohm speakers
I'm not familiar with the specific amp, but I would assume that the answer is "no." Presumably the output transformer is designed such that the output tubes see essentially the same load when a 4 ohm speaker is connected to the 4 ohm tap as when a... 
Speaker hum problem - need help
Quite a mystery. At this point I can think of only two possibilities, both of which seem very unlikely:1)The electricians who wired the house when it was built messed up big time, perhaps leaving a safety ground run unconnected, or even reversing ... 
Zyx Universe. O.24 mv vs .48 mv with low eff spkrs
05-23-14: SwampwalkerMy own experience is that you do have to be somewhat concerned about hum and noise when you go to very high eff speakers; the higher eff the more careful you have to be....Relevant to this point I see that the MA-1's descripti... 
Speaker hum problem - need help
Do either or both of the upgraded outlets have a small triangle symbol on them, signifying that they are isolated ground types? Did you install the upgraded outlets yourself, or did an electrician install them? Is there a basis for confidence that... 
Speaker hum problem - need help
Dan & Bruce, fair points, but the probability that effects at the inputs are causing the problem would seem to be low given that the hum is insensitive to the volume control setting.Matt, given your thorough (and excellent) description of the ... 
Lossless Files Vs CD's
05-22-14: DvavcBut of course ripped files are sound inferior compared to it's sourced CD.... Let's do very simple test and compare apples to apples, that you can witness said difference for yourself.... Now, using any software of your choice, letÂ’... 
Yaqin MC-10T no bass?
Even though the speakers are rated as being 8 ohms, if you already haven't it would probably be worthwhile seeing how they sound when connected to the 4 ohm taps on the amplifier. Two-way speakers such as these frequently have considerably lower i... 
REFURBISHING VINTAGE TUBE RADIOS-
Links to the websites of a number of antique radio repair services are included in this list. I have no specific knowledge of any of them, however.Regards,-- Al 
Zyx Universe. O.24 mv vs .48 mv with low eff spkrs
05-22-14: DougdeaconAlmarg,Thanks as always for your willingness to share technical knowledge. Most of my postings are based on what I hear and seat of the pants "thinking". It's always helpful to hear from someone who actually understands what he... 
REL Subs with ARC Ref series amps
Thanks for publicizing this excellent info.I recall seeing schematics on the web for two or three older (non-REF) ARC power amps which showed the 4 ohm tap as being connected to the amp's circuit ground, with all of the other taps (including the 0... 
Interesting bilind testing of Stradivarius Violin
05-21-14: Onhwy61Just out of curiosity, what other vintage objects are considered superior to their modern equivalents? I don't mean more desirable or valuable, but actually better at their intended task.As a collector of such things, I can attest...
