Mr. Pass,
Is there any posibility to make a ''perfect'' X250.5 or X350.5 amp?
(keeping working principle as how it was but maybe using best of the best parts and internal wiring?)

Mert

No. The design is not perfect. When I create a perfect amplifier,
I will disappear in a puff of smoke.
The X series is most easily improved by increasing the bias,
which generally means better heat sinking and power supply.
There are the usual tweaks, your favorite capacitors, wire,
resistors, etc, many of which work, adding some small measure
of improvement.
It's not hard to form a list - unfortunately the items on it cost
a lot of money. We have used all the economical approaches
we know, and some that are not.

Have not seen much of you lately😀 .
My feeling is as an X250.5 user if you think it needs improving something else is wrong. Buy a Lavry Dac and a Passlabs X2.5.
Game over Man, Game Over!😎

Mr. Pass,
''increasing the bias'' means forcing the amp. to run more in Pure Class A mode under constant power?
Secondly, do you make custom built amps?( improving the internal parts, heat sink, power supply..)
Thirdly,
Have you ever heard liquid cooling?

1) Any increase in bias is good, and it doesn't have to be
in pure Class A.
2) No.
3) Yes.

Is there any chance to apply liquid cooling on amplifiers?(pc nuts apply to motherboard, ram, processor, harddisk, graphic card....pc works without fans)Nelson Pass said:
I've done a fair amount of work on water cooled circuits. I did a thread on it at one point. I am still using the same setup and still think it's the easiest way to deal with heat...however, it's not portable. How big a problem that is to you is for you to decide.
It's not the sort of thing that you can retrofit to an existing amp. You'll have to start from scratch. However, the system I've got will dissipate something on the order of 2kW of heat without breaking a sweat (ahem). I've never found the limit of what the system can do.
Incidentally, I make no claims that water cooling sounds different (setting aside mechanical noise from the pump, which is in another room anyway), only that it's a very efficient way to move heat.

check thermaltake water coolers, there is usefull information how their system works.

Just the amp in another room and force air cool it.
Be careful of the bias settings. They are quite sensitive and it will take some time to balance everything.
In any case this is not something I would recommend
You can experience the joy of simply increasing the bias with a passdiy project.
