Do tell. In a very long winded markl like manner... Don't forget about at least 4 pages on the power cord alone.

So here is a bit more entertainment. On ray's portables there is that big 10000 uf cap, and a source impedance that charges it of about 5 ohms. So a total charging time of about 200 milliseconds. Yet it takes months and months to burn in, so says ray. mikhail's thing is 2 x 1000 uf caps in parallel charged by a 1 meg resistor. charging time of about 63000 seconds... or about 18 hours. So true burn in takes about an eon or so...

But wait, there is more. Each individual output transistor is its own amplifier. So a balanced dynafet would be a 32 channel amp. But wait there is even more. A krell master reference monoblock as as stereo pair would be a 240 channel amplifier. The crap flowing from mikhail's mouth is just plain stupid. Like his steadfast insistence that the cathode resistor on the extreme is not really a resistor but rather a current sink. Same thing with the plate resistor on the ES1. Nope, its not a resistor, but rather a current source. Both sure look like resistors to me... Even ray has finally shut up about his $200 an inch military wire...

where is my shovel. I need to bury something. So my understanding is that a "push" is an amplifier, and a "pull" is another amplifier and for balanced you have a total of 8. New math, gotta love it. Then the standard square wave is a 4 channel amp??

Well bryston for one. But that is not what i'm referring to...

That and using all the remote control switching and attenuator products from Liteaudio of china, changing the led's to blue and then saying its completely custom. Its actually fun to try and get into a designers head and figure out how they come up with stuff. Clearly stuff from john curl, nelson pass, james bongiono, dan d'agostino, charles hanson... all have very distinctive and different, and immediately noticable design philosophy's. When i try to get into mikhail's head all i see is re-runs of "yellow submarine" and a lot of this stuff C20 H25 N3 O ((6aR,9R)-N,N-diethyl-7-methyl-4,6,6a,7,8,9-hexahydroindolo-[4,3-fg]quinoline-9-carboxamide) And to be fair, when i try and get into ray's head, all i see is the vast vacuum of space.

Not even close to the same. srm-001 is a capacitively coupled output single high voltage design with an opamp front end. The others are basically portable versions of the dc coupled srm-313 and run at lower voltages and lower currents. All 3 use a switching power supply. The sr-001 makes +600, +12 and -12 The other 2 make + and - 300

Need picture of XL to confirm. Here is my guess, the area taken up by the input switching and room for the dac is gone, replaced by a total of 4 amplifier circuits. 2 of which have the capacitor outputs. These are the + output of the balanced, and the output for the unbalanced. The - outputs of the balanced don't really need output caps. Since mikhail is absolutely so against any opamps, there is some cheesy unity gain inverter made out of a pair of fets to drive the - output when in unbalanced in/balanced out mode. Obviously there is no inverter necessary when running in balanced in/balanced out mode. I have figured out where mikhail got his output stage from and i have notified that person.

updated schematic, same name same place. I cannot find the words to accurately describe what i think of the capacitor output section...

I wonder what he does with the +5 volts

How much you wanna bet that the SS1 beast ($14k) is roughly the same thing on the inside. What a really mean joke to play on unsuspecting people.

you are absolutely correct... No local power supply caps... pretty grim huh?? how do you like the adjustable bias by jumpering across (or otherwise removing) one of the diodes... all that space wasted when they could and should be power supply caps, and then a simple opamp servo to control the dc level. Still hoping that one day i see something good from mikhail. Same thing with ray... Next time mikhail may do a solid state amplifier with an output transformer. (very McIntosh like)

oops, forgot the 2000uf of output capacitors per channel :D output capacitors on a solid state amplifier Reminds me of a dynaco Stereo 120

much better now. http://gilmore.chem.northwestern.edu/dinglepower2.jpg complementary sziklai pair with gain.

there is a slight error in the schematic which most of you won't catch... Will fix later.

Exactly true. Plus the complete lack of a sub-bass filter destroys expensive full range speakers. You can get a way better phono section for less than half the price. And they will be far less noisy too.

i usually can draw a schematic from very little, but this is below that limit Its a single ended single tetrode tube per channel with transformer output. Duplication would require the same output transformers...

yep thats the $50 dac board. Nice soldering job on the audio output connector, or whats left of it. Guess that for $1k all you get is this piece of shit.

Stop messing around and build a circlotron. You know you want to...

Assuming the 8 pin chip next to the uac3553b is an eeprom, it holds all of the configuration data. Some of that data includes the dynamic bass configuration stuff. So likely the eeprom got zotched and needs to be reprogrammed. The dac board does not look like mikhail's work, so you need to figure out who made it and see if it is upgradable or configurable over the usb port. (highly likely it is with proper software) Its the Xitel board, and software is available under non-disclosure...

If its the amp i'm thinking of, the step attenuators are for the headphone section, and the digital remote controlled thing is a computer controlled attenuator made by lite (DIYclub) and is used as the passive preamp. DIYCLUB

I just added another 4T to my storage array. At the current price of storage, i doubt i will ever run out of space ever again.

Isn't that off, and Ray Samuels

OK, so how much did it cost, and why doesn't the rest of mikhail's stuff look like that. If you are going to pay premium prices you should at least get this level of quality. It's still not perfect, but way better than the rest of the stuff we have seen. It would still be a bitch to repair.
