Zanden Aiudio Chouku - new statement mono amp from Zanden Audio

[andromedaaudio]

Its diy so that will forever be a mysterie i pressume ,however i do trust mr yamada(zanden ) regarding his designs , ive heard quite a few ,and own one myself and my expirience is there really is not much to wish for anymore , which makes it kinda boring

This is what the Zanden Chouku looks like with the fully assembled cabinet:

Some more Pictures:







Apparently the the Chouku is only made for Audio Exotics in Hong Kong but I have inquired about availability anyway.

The output transformer has a core made from FINEMET - a super material only available from HITACHI Corporation.

This may well be a great sounding amp, I'm just not a fan of amps that look like they were built into a computer tower case. Can you say VTL, ARC, Dart, and a few others (ML to name another one)?

Audio Exotics has some interesting forums and exposure to some different gear than we always see in the USA. It's partially what turned me on to most recent purchase...Robert Koda K-10 preamp. This Zanden amp really seems interesting...

I on the other hand really like that.

Agree...they are passionate extremists over there...but some of the stuff they rave about really is great. You own one of them (koda) so you know what i Am talking about. I would love to hear the new Zanden amp...love their digital and have heard the ref monos.

In holland there was a guy (diy) who designed an amp around the TB3 - 2000 , the 833 is a dwarf compared to that thing.

http://forum.zelfbouwaudio.nl/viewtopic.php?f=7&t=12736 scroll down for pics absolutely massive , never heard it unfortunately

There you have some single ended power

Look up the ML-6696A or -6697A (60 kW), or even the Eimacs 3CV200000D3 or ML-7482 (200 kW). Makes the little 2 kW ham tubes look tiny... I helped at a radio/TV station that used some large RF tubes in their 100 kW transmitters, water or vapor cooled. Serious antenna feeds (coax to the antenna had nitrogen piped through to expel any air and moisture).

 

[andromedaaudio]

Pretty big the first one , but does it have a glass bulb or something else with liquid cooling???

Interesting read about aging and "" seasoning "" of tubes on page 3

Maybe the tube designers should design some 1 KW triodes, maybe then the SS guys with vampire loudspeakers will stop complaining how bad tubes sound .

I hope the dutch zanden importer will buy a pair of choukus so i can listen to them at a show

Ps ive just polished my zanden with degreasing spray its like new again , and i doubt i ll ever sell it

 

[andromedaaudio]

Roysen tip :why dont you buy a pair of choukus plus a pair of XLFs and get the whole amplification problem (biamping what ever ) over with , 40 watts per channel should work fine.
