AR & CJ's Secrets?
Over the years, looking back at the Audio Research D-76, D-150 Amp, and the
most revered SP-10 & 11 preamps, I have to wonder, how do they do it? I know this question is rather sophomoric, but your answers may be able to put many things into perspective for me, thusly I will be most appreciative for all your comments. Many of you have designed incredible amps and preamps over the years with similar components and circuitry, but what does AR & CJ do differently that we (at lest the upper echelon Rodents) can not duplicate? I heard these aforementioned equipment and simply had a life experience. Do you think it's something as simple as proprietary Xfrs? Remember the lush, romantic midrange to kill for by Conrad Johnson's CJ-5 preamp? What was so special about that circuit? Cordially, west |

Cordially, west AR and CJ wouldn't have sold many amps unless they advertised fiendishly. They also got in on the ground floor a long time ago before many other names. If anyone tries to build a tube amp empire in the US these days they'd be committing financial suicide unless they engage the services of all the friends they could muster in China. Then its a Chinese amp. But anyway, after the first few nice simple things these companies made, they tended to use maybe 11 devices in a signal path when only 3 would be fine. I don't think they have a monopoly on being able to produce excellent sounding amps; plenty others do OK, and I don't know if you have ever serviced many of either, I have, and some of them are plain difficult, awkward, and over-riddled with complexity and parts, some of which have had their numbers removed to prevent anyone knowing exactly what j-fet they may have used, so you can't just buy a generic part from any dealers. Any dedicated audiophile with practical and technical abilities can make something at home that will perform as well or better than the high end amps. Patrick Turner. |
