Norman is spot in his comments regarding Jian Liu, my experience
through out the transaction was the same - just excellent !
My NOS RCA tubes arrived this afternoon and I've been warming them up
this evening - ooh baby very nice sound indeed and that's considering they
still need a few hours on them !
I had to open the case to have a peek inside and noticed that the wiring has been tidied up since the first version of the 336 ( no "i" suffix ) but I have to say as neat it may be the use of decent wiring like what Fitz did is much more preferable from my point of view for servicability ! To everybody else, it isn't going to matter.
This unit is DEAD silent, no hum what so ever ! It's even quieter than my Mapletree Audio Design Ear + purist !!!!
I only have two complaints about this amp and both don't relate to it's sonic abilities. Firstly, that BRIGHT Blue LED just has to go ! Man it must be at least 4000 Mcd, bright and powerful enough to give you laser eye surgery from across a darkened room. Secondly, the volume pot as Fitz had previously mentioned doesn't give you enough variation of control over the volume. You go from no volume to full volume in less than one fifth of a turn of the volume knob, so I've ordered an Alps Blue Velvet 100k logarithmic pot off eBay already !
Hope you get your amp soon Norman !
I'm off to soak in some tunes for the evening because I have the day off from work tomorrow !
