6SN7 based Pre-Amplifier

Dehavilland

there seems to be a 6sn7 variant of the aikido I think is worth looking into.

Thank you all for your suggestions.

I had the opportunity to listen to a Canary CA906 (2 6sn7s per channel with extensive tube rectification and regulation) in my system with both the VAC Phis and NP220s.
This is probably the best production preamp I have every heard.
Details later.

I wrote a mini-review on the CA906 and submitted it to www.high-endaudio.com.

Just bit the bullet on a Ming Da MC-2A3.
Not nearly the same class as the CA906 in terms of build
(I have NEVER seen layout and soldering as good as Canary products),
quality of components used, and most importantly sound but
there's a big difference in price.

Ming Da MC-2A3's hopeful for mods given the space available inside and rather easily understandable layout. Weird power supply though,
gives all the attention to the B+ not zero regard for filament voltage.

Also not all MC-2A3s are the same... some boasts M-Caps and other
premium components. Mine has MKPs and what looks like Vintage Gudeman. Also the 'Philips' caps look suspicious.

If I had ample $$ I'd go for the Canary 906, but the Ming-da is gonna be quite a bit of fun I suppose.
