The Best Amplifier Ever ?
Technically, the HALCRO has the *best* on paper distortion specs *ever.* I have not seen any actual *bench tests* so far. If they are published anywhere online or someone can email them to me I would be very very interested to see the graphs (like... 
Instructions to electrician about dedicated line
Sure, Sean, that's pretty good in principle - but you have to think about what happens to the grounds too...Also, are you saying multiple 240vac lines, or 120vac lines?One of the advantages of the 240-->120 stepdown is that it makes for a way s... 
Instructions to electrician about dedicated line
If you can afford it, use BX and make it 10 ga.Run 220 vac if you can to iso transformers for step down.OR, use a single large ISO tranny in the basement to providelocal power... isolate each line with an RFI/EMI filter.Put a big ass GROUND wire o... 
Tubes Do It -- Transistors Don't.
There is no doubt that tubes come in various flavors and colors, some of which are quite nice. Some are really awful, I'll leave it to you to discern. Imho, for little money you can get a really *nice* sounding amplifier using tubes, one that give... 
Where to find info on the acclaimed parasound JC-1
FYI, Crump owned and used my Symphony No.1 Amp for at least a decade in his system. Also Silver Lightning interconnects too. Then he decided to start his own thing, and hooked up with Curl. He didn't sell the Symphony No.1 amp right away... his ca... 
Trying to Enter the "HiFi" Bizz
I think ZSquared hit it on the head - a PILE OF FRIGGIN MONEY is what you need first. After that, don't be a fool, and you'll do fine. :- )Oh, you ought to have a product that hits at least a niche, and has technical competence. Anyone who has a p... 
TUBE or S/S Phono Amp with an all s/s system?
There is no simple answer... much depends upon your system. Since you're into Krell now, you've got a certain sound to your system (which in this case depends upon the vintage of your Krells). You could pick a phono preamp based on a desired color... 
Where to find info on the acclaimed parasound JC-1
Ummm... I think ur confused... the JC-1 was John Curl's first preamp. Levinson sold it and the JC-2, iirc.Parasound sells equipment now that is designed by John Curl, including the power amps (2200?)and I suppose a preamp as well... are they calli... 
What type of solder do you use and why?
Go for the 2%Silver w/ lead containing solder. Not the lead free.The lead melts, it doesn't vaporize. 
What type of solder do you use and why?
IT is again important to note the difference between "SILVER SOLDER" and *silver bearing* electronic solder. High melting point silver solder (jewelery, refrigeration, etc. applications) is generally NOT suitable for electronic use.You *want* silv... 
How hot is hot enough?
"Silver Solder" is NOT the same thing as "silver bearing solder." You want the latter stuff - intended for electronic applications. The other stuff is higher temp and is intended for applications like refrigeration. NG for electronics because the ... 
What's better 100w class a or 200w class ab?
Ummm that 72 amp "peak current" thing is a bit, shall we say, "optimistic." Let's take a look at it. In order to get 72 amps drawn by a load it has to fit into the P = I^2 R formula. So, 250w = 72^2 * R - where 250 watts is the max output of the a... 
Mosfet amps A true compromise betw. tubes and SS?
Mosfets & Hybrid amps = not equal. On one hand Mosfets are actually "pentodes" when it comes to the transfer curve. So, to that extent they are "tubish." They also tend to have a soft saturation, meaning that they tend to clip gracefully, not ... 
Amplifier Fan
You want a "Whisper Fan" which is the brand name for quiet, slow fans from Rotron... designed for this sort of application. As noted, your amp should be free of obstructions - not in a cabinet or other enclosure, and be able to freely circulate ai... 
What's better 100w class a or 200w class ab?
I'd reckon that the biggest question is what is the impedance of the speaker? Since this fellow is deciding between two amps from the same mfr, the biggest diff will come IF the "class A" amp slides into AB because of a low Z load. In which case i...
