McCormack , Aragon or Forte
Yes Unsound you are correct, the one I had I in for bias control repair I think I remember now were BJT (bi-polar), 2N3055 & MJ2955 or MJE15003 & MJE15004. Don't know were I got the IGBT from. They can still push current as just as well al... 
McCormack , Aragon or Forte
The Forte amps to me have a pedigree that is hard to beat, the designer of which I believe is Nelson Pass (one of the gods if not the god of SS amp design).I had one here for repair a while back, can't remember which one it was but it sounded very... 
Lightspeed Attenuator - Best Preamp Ever?
Banquo363 that site takes Payapl, so you will also have it's buyer protection. And I believe their postage is reasonable, and you get to order the right voltage for you country as well.Cheers George 
Impedance mismatch question
Al sorry I should have mentioned at the end of the day a Cymer tube pre with 2k capacitor coupled output impedance was subsituted for the Lightspeed and similar ratio results were observed. Of course as you say being tube tube and capacitor couple... 
Impedance Matching
Stickman451 hi, I have post on a similar thread some extensive tests that were done that should answer your question here; http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1387725945&readCheers George 
Impedance mismatch question
Hi 2out2sea there is no hard rule here. We've done experiments with very good equipment with 30 odd audiophiles where we could vary on the fly the impedance ratio from 1:100 down to 1:1 (your case is 1:23)We started at 1:100 with these listening t... 
Lightspeed Attenuator - Best Preamp Ever?
No I have not tried it, but I have compared pure battery power to the standard supplied power supply, and the difference is subtle, you can't put your finger on it, that subtle that you forget which is on.I posted this power supply as it looks imp... 
Lightspeed Attenuator - Best Preamp Ever?
Those who have a Lightspeed Attenuator and wishing to try a different power supply instead of going battery. I've been shown this quite reasonable priced one which is a nice linear regulated product. And comes with the correct lead, plug and polar... 
Advice on selecting a tube amp
Nicknac, Tubes and tube socketts are not friends of moisture, esspecially if it's salt air. I know from experience being on a boat space is a premium, your speakers are good quality in a small package and efficient at 90db. This Cambridge Audio wh... 
The future of preamps
Atmasphere: "The rule of thumb here is: If you can hear differences between interconnect cables then the source is not controlling the cable."Sorry, wrong again Atmasphere, the only time all cables will be made to sound the same/equal. Is when the... 
The future of preamps
You you didn't even bother to look before making ridiculous statements of this system quote: "this is not really true, unless that source also has the ability to control the cable." You put a White Paper out on this Atmasphere and you'll be shot d... 
The future of preamps
Here we go again, the flat earthers rebuke. I didn't even mention the Lightspeed Attenuator or passives. "I said if his source has volume control" it will be the most transparent, dynamic, and least coloured way of getting the sound of the CDP/DAC... 
The future of preamps
Don't worry Phusis and others you have it right don't listen to them. When ever there is a thread that threatens the existence of preamps these three to four flat earthers always rear their heads. It's almost like they have shares the slowly decay... 
Best amplifier for CLX
I would still back going direct into the amps over the Accuphase pre, so long as the cdp/dac has digital domain volume and it's being use in the top 30% of it's range so as not to do any "Bit Striping"Cheers George 
Best amplifier for CLX
BvdimanC3800 Marantz Pre??If you mean this, it may have been ok in it's day but to partner it with the stuff we are talking about here and these CLX speakers, it's way out of it's league. The poor little signal from the source that he has would ha...
