(going off the review) Some say I'm not "audiophilic" enough but I had the misfortune of seeing one of these on the shelves and grabbed a L300 just to make it easier for it. Nope, I rather listen to a 252S and I don't even remotely like a 252 Quote Link to comment Share on other sites More sharing options...

Seems like it's better to just do one very well than try to stuff both in a box. Nope, they are just very different technology so even if you had two separate amps in the same box, there would be issues.

kevin gilmore Posted June 4, 2023 Report Share Posted June 4, 2023 actually a krell master reference pair of monoblocks will drive any headphone electrostatic or dynamic. just need to add a bias supply. 800 volts peak to peak. 1 2 Quote Link to comment Share on other sites More sharing options...

I was thinking stack a Liquid Lightning on my AGD amp/dac Wire 4/5 of the Stax plug pins to the Cavalli Wire the 5th to an RCA on the back of the AGD I'm a mechanical , not electrical engineer, but I think this will do 1 Quote Link to comment Share on other sites More sharing options...

justin Posted July 1, 2023 Report Share Posted July 1, 2023 (edited) On 4/14/2023 at 11:46 PM, Kung said: Ray samuels the old friend of stax mafia just released a new amplifier B-21, the electrostatic part claimed 1800Vpp voltage swing with 200mA continuous current output performance just shocked me. . . Reminds me of the horribly weak output performance of the A10 he designed before, this new amp is also questionable... I tried the amp @ CanJam and thought, hmm wait a minute, the knob is only at 11 and I'm listening THIS LOUD to STAX? That's when I realized.. the gain is ~2400x, which is the highest I have heard of for an electrostatic amp (STAX amps typically 500x to 1000x) but makes perfect sense for demonstrations in a loud room. I changed the gain tube in the Grand Cayman (720x gain) from 12SN7 to 12SL7, which did the trick But that was the end of the show, so...next time Edited July 1, 2023 by justin 1 1 8 Quote Link to comment Share on other sites More sharing options...
Kung Posted July 3, 2023 Report Share Posted July 3, 2023 damn, 2400x the gain, that must be loud enough to explode... there are audiophiles who judge the power of the amplifier by the position of the potentiometer knob, i guess ray samuels should have a good knowledge of this.

If you use a shunting pot (configuration B below) built with a regular audio taper pot instead of a quad pot in a balanced design, besides being both cheaper and inherently symmetrical, nearly all of the taper is in the first half which makes amps appear to these sorts of people as being more powerful than they actually are. 1 Quote Link to comment Share on other sites More sharing options...

kevin gilmore Posted July 3, 2023 Report Share Posted July 3, 2023 actually by increasing the gain on the apex part you seriously compromise the high frequency response and increase distortion. which may be intentional. Quote Link to comment Share on other sites More sharing options...

Pars Posted July 10, 2023 Report Share Posted July 10, 2023 (edited) If I bother looking at the CFA3 thread on HF, there is a lot of talk of using tube preamps in front of a CFA3. I agree, don't understand it. Edited July 10, 2023 by Pars Quote Link to comment Share on other sites More sharing options...
spritzer Posted July 10, 2023 Report Share Posted July 10, 2023 Might be to get more volume out of the amp as for a lot of people... moar loud... moar powah!!! Quote Link to comment Share on other sites More sharing options...
Timb5881 Posted July 11, 2023 Report Share Posted July 11, 2023 Or it could be that they are using sources such as DAPs or USB stick amp/ DACs, they can use a bit of a boost. Quote Link to comment Share on other sites More sharing options...
justin Posted July 28, 2023 Report Share Posted July 28, 2023 SR-X9000 just passed 1,000 units manufactured. Took just under 2 years 2 Quote Link to comment Share on other sites More sharing options...
spritzer Posted July 28, 2023 Report Share Posted July 28, 2023 That's impressive... shame they sound like shit. Something new for me, I came across my first ever arc'ed over SR-007 driver yesterday. Utter carnage in there, a hole in the diaphragm roughly 30mm across and burn marks on both stators. Other driver was just fine but yeah, there is a reason we fit protection circuits. 5 Quote Link to comment Share on other sites More sharing options...
