Explain Class A amp to non audiophile friends
Charles1dad, Yes it is. You have to keep in mind though that the ear hears many distortions as tonality issues. Also, the presence of distortion tends to obscure detail so in the range where the distortion appears the amp will likely sound harsher... 
Tube Preamp Paired with Tube Phono Stage?
Actusreus, if Fremer is not 'full of it', he was hearing those differences due to issues with the **phono section(s)** rather than the cartridges. 47K, 100 ohms, the cartridge does not care. I run my cartridges (Transfiguration Orpheus, ZYX Univer... 
Need understanding on amperage
Right! Now this is just my feeling about the matter, but I don't think the 60 amp rating is realistic if it means that the amplifier could be damaged or the like in the process. At that point we are clearly operating outside of the linear region o... 
Cleaning the equipment
We sent a preamp to TAS for review back about 15 years ago or so. It died when hp's cat urinated in it so we got it back for repair. Yuck!The only way to sort it out was the manual high-pressure car wash. While others were washing mud off their pi... 
$$$Sensitive Speakers with $$Amps?
Charles1dad, its not like I listen to those levels all the time! But there are certain LPs, that in order to sound life-like, have to be allowed to do what the composer and musicians had in mind. The Verdi Requiem (RCA Soria edition), side one tra... 
$$$Sensitive Speakers with $$Amps?
Charles1dad, I think I did that last post pretty poorly! I meant to confirm most of Joe's comments. I was editing my post and deleted that part, then forgot about it. What I was commenting on really only applied to the M-60s he is using, which are... 
Analytical or Musical Which way to go?
The quote goes"If it measures well but sounds bad you measured the wrong thing."The above is a fact, and is also pragmatic. Most measurements do a poor job as they really are not attending to human hearing rules. 'Musical' to me implies accurate w... 
Tube Preamp Paired with Tube Phono Stage?
Actusreus, (in case its not clear from Al's comments) the reason some preamps offer more loading settings, and that they are audible has to do with the fact that such preamps are not 'graceful', as Al put it, when dealing with RF energy. IOW, the ... 
Need understanding on amperage
Dhl93449, your math looks right but your conclusion doesn't. At the end of 10mS the supply voltage is only 24V so the current would be 24 amps- only 576 watts. The fuse would go a little longer and the 3600 watt figure would go much shorter or am ... 
$$$Sensitive Speakers with $$Amps?
Trelja's experience flies in the face of what our other Horning customers report, but it might have something to do with Joe's amps being 12-15 years old without any updates (its clearly time, Joe- you know the warranty reactivates with the update... 
Need understanding on amperage
Tonywinsc, that music has such transients and that a stereo needs either very high power and/or efficient speakers to reproduce those transients is not a matter of debate.What is a matter of debate is the math. Its more than just the current ratin... 
Oil For Nottingham Spacedeck?
It doesn't foam up and lasts a long time. For turntables and tape machines its about as close as you get to a universal lubricant. 
Tube Preamp Paired with Tube Phono Stage?
This is almost as frustrating as John Curl's JC-3 phono preamp offering only one impedance setting of 100 Ohms for MC. That one I'll never understand. The reason is if the preamp is resistant to RF at its input, the load on the LOMC is not critica... 
are some phono stages more resistant to hum?
To clarify my comments, phono carts are ISOLATED devices, but are not inherently balanced. A true balanced voltage source would produce a symmetric V+ and V- signal referenced to common.A common method I use to identify a balanced source is what h... 
$$$Sensitive Speakers with $$Amps?
Our amps only have one stage of gain. Hard to get simpler than that. In general its been my impression that cost is less important than the simple fact that some amps sound more like music than others. So my answer is now 'depends' as there are ex...
