Really, really extreme phono, more extreme than mine

Hi!

Maybe you know me by now but does anyboby know any extreme phono amp if we talk circuit design and/or mechanical design?

I'm collecting schematics over phono amps and I notice that many commercial ones are surprisingly simple (and some of them not very well sounding, not even for "non-golden ears")

I'm curious about the X-LP Can amp. Schematics?

I can't delver the schematics, but if you are looking for extreme phono amplifiers, you might have a look at this one:

Don't know the retail price in the US, here in germany it is about 35000$...

Beautifull!!

Apart from the fact that all that logic can be replaced by a single 20pin dip PIC, that they apparently made a mistake with the alinement of the ribbon connectors and that the quality of the supply will be largely negated by the many solder- and plug connections to get the supply to the main chassis, and a few other things that could be better, not bad at all. $ 35k you said?

The only nice thing about the Boulder is 3/4" thick front and rear panel, maybe the buttons too.

What I remember, Day-Sequerra phono stage was highly regarded in a golden age of vinyl.

Could not find link for extreme audio design though.... Don't forget to wear your helmet while soldering and be sure to use an extremely large number of parts.

Certainly not that extreme, but maybe interesting:

Don't throw rocks at the Boulder people. No more parts than the ML stuff. It is pretty funny when you think about it though......

P.S. More fun from Boulder......

Hi guys,

Just wonder what good balanced outputs are going to do when you don't have balanced inputs ?
I'd say go all the way or don't go at all,right?

That boulder amp of course has balanced inputs.

Hi,

I stand corrected and red-cheeked.
