so many different amplifiers and variations. All tube, some tube and all solid state. including an amp with TWT's

and more coming once i get that felista megatron off my bench.

in other news dukei has the tube input stage running. no idea if he likes it or not

We should start a poll. I'm going with hates it.

How is it compared to Carbon?

If you are referencing the cfaelectrostat, that is one of the very few I haven't heard. It was made to be, say, a budget or easy amp. It likely compares well with KGSSHV.

I like it! I've had a couple of hours with it but my initial impression is that it brings life to headphones that struggle with unengaging/analytical midrange and treble (think HD800). Bass quality and transient speed are equal to CFA3, which is positive.

Have to spend more time with it and different tubes, my amp queue is crowded atm...

This is very good news, and very bad news, and very inevitable.

Any chance on taking a felitsa cfa after that Dr. G?

 

[Ethereal Sound]

Someone could make a pretty penny opening up a shop to fix up all the felitsa amps at this rate..

So the latest i have found on the cfa3 is that he is using known fake toshiba output transistors and as a result, the power supply voltages are turned down to 24v.
(real toshiba parts are rated at 180v, the fakes blow up at about 50v). and the power supply are not using tantalum caps in the places where they are needed, and the opamps are pulled parts with 20+ year old date codes. and the circuit boards are hacked up to get the transistors closer to the heatsinks because he refuses to use angle brackets on most units. And resistors pulled to the circuit boards way to tight and on and on and on. There is nothing left to salvage except for a poorly machined chassis.
Saving maybe $100 on parts for a $3000 amplifier is beyond insane.

No one with half a brain would try to repair one of these things. Although i know at least 3 different people who are desperately going to try.

No one with half a brain should buy one of these things. Buy from dukei instead.

i will finally have the rest of the power transformers in a couple of weeks to finish the megatron. It was not worth the time and money to fix it.

At this rate, will the Felitsa amps one day reach the same legendary status as Single Power amps?

 

[kevin gilmore]

the felista megatron is already way past the singlepower esx. way past. at least mikhail could put the holes in the right place.

Does the person who builds the Felista stuff realize how much he is messing up the design? Is this person making conscious choices to hurt the amp and therefore good hard working people in this community? Is it all about making a buck?

I hope it isn’t this cynical, but feeling it may just be…

The megatron, there is just no explanation for this. Definitely not to save money. labor for handmade with a dremel circuit boards cannot possibly be cheaper than jlbpcb even with vietnamese labor rates.

changing the caps on the grlv supplies definitely saves money. For two power supply boards that is 8 x tantalum caps, cost about $60. replacement with ceramic caps saves about $40. There is a slight possibility that the ceramic caps in those positions perform equally well, but i tried that a long time ago and stuck with the tantalum.
using pulled surplus parts also saves some money. not using ic sockets saves some money. using fake output transistors definitely saves money.

Has anyone compared the CFA-3 with the Ferrum OOR before?

 

[buzzlulu]

Or with the Bakoon/Enleum?

 

[EstrangedBaron]

Or with the Bakoon/Enleum?

I found one review of the Bakoon 13R VS CFA 3 here: https://www.head-fi.org/threads/hifiman-susvara.853031/page-911#post-16752381

Well, with some amps he builds them and doesn't even bother to test they work properly.
