I have the Studio Reference II.
I'm saving it for the 250Ti because bi-amping with the PS400 and PS200 on the 4345 works just fine!

Some things came to mind that I thought you should know regarding Crown vs. the Bryston amp.A friend just replaced his Bryston 14B SST with a Crown CTS... he has not looked back and do prefer the Crown over the BrystonAnother one replaced his Holton amps With another Crown CTS and he was shocked about the performance of Crown.
1. That is an old model Bryston. The series 2 (which is getting old also) 14B is completely revamped. Filter caps, transformers, transistors, everything.
2. Bryston's not the greatest in sound anyway. They've always been middle of the road sound wise. I should know, I've had their stuff for 8 years now.
3. If you told me better than Pass Labs, Accuphase, the latest McIntosh stuff, or even the new ATI 6002 amp, I would be impressed, regardless if I would believe you or not! And I wouldn't!

Why did you sell the Studio Ref?I've had Studio Reference also
CTS600 and 1200 are class a/b but CTS2000 and 3000 is not, they are class I!
Ahh yes, I didn't mention that. Only the smaller models are A/B. That is actually why I chose like I did... A/B for LCR and Class I for subs. If I am not mistaken, Class I sounds best full range if you bridge it. It will double the switching rate. Correct me if I am wrong, but Mark Levinson amps are actually Class I as well but with higher switching rate than the Crowns (also iTechs).
The end of my Techron 7570 vs I-TECH 5000HD comparison.
One thing I have come to know with me at least is that I am better at recognizing deficiencies faster than good qualities when it comes to subtile ques in audio and often I will swap something into a system and not at once recognize a subtile difference if the difference is posative as compared to what was just displaced. When I usually notice is when I go back and it sounds worse.
Today I put the Techron's back in place of the I-TECH 5000HD's and I am not unhappy. They just sound great. The RFI and power grid noise is happily absent as is the fan noise.
The I-TECH will find a home in another system.

If we knew what the hell we were doing, we wouldn't call it research would we.
Get that 7780 or whatever it is running!
If nothing else, you'll be the only kid on your block - guaranteed!
Yeah I need to wire an outlet and power it up, big fun for sure.

what is that thing? for like an x-ray machine or something?
I think SLAC is looking for one of their beam focusing power supplies that have gone missing.what is that thing? for like an x-ray machine or something?

what a beast!
It looks like the output circuit was designed by Crown.
It also look like it can do current-drive instead of voltage-drive?...
Is that the case?
It's an A/C!what is that thing? for like an x-ray machine or something?

No worries, it was their spare. One of the kids sold it to me for beer money, and I believe it is brand new.I think SLAC is looking for one of their beam focusing power supplies that have gone missing.

Correct on all accounts.

As near as I can tell, of all the common configurations of the 7700 series, only two of them, the 7780 and 7782 are low frequency amps. These are flat from DC to 40kHz and extend to 100kHz but are down to single digit Watt output by 100k.
I have to revisit the specifics for the one I have, one is optimized for loads below one Ohm and one for loads above one Ohm. This one will swing over 200V into a half Ohm load at 38 Amps. The output connectors are for four gage wire. This thing is just plane silly!
My plan is to see how many 2242's it will drive.

Close! It is a heater!
