Review:
Well what can I say the amp arrived 3 days from leaving Hong Kong, yes three days.
These guys are without doubt the kindest, most polite, patient, that I have EVER come across in any business no matter where.
They responded to my emails within minutes, any time of the day. PERFECT, as a company I cannot racommend them highly enough, there should be another 10 stars to the rating.
Anyway the AMP:
in a word WOW, this is up there and probably beats all of the amps that I have owned and that includes many costing 2 to 3 times more.
The amp is not even run in, literally had it on for 30 minutes to warm through.
Soundstaging is amoungst the best, precise and about 6 foot infront of the speakers. The detai is, well, real, trumpets sound like trumpets, but still with that gorgeous smooth valve sound, no harshness whatsoever, unless the recording is that way.
Build: Built to a very very high standard, aluminium so thick it could stand a small explosion!! and as for the remote, machined from a single peice of aluminium.
Forget your over priced british stuff as good as it is, you would have to spend many many times more to equal the sound of this one.
China is where I am now getting my hifi from, in fact I have a CD player on the way.
These guys are first rate and care about the products they sell and how they sell them, first rate customer service. Just wish that I could pop over there to meet them, and see the amps being made.
LOOK OUT BRITISH HIFI BE ON YOUR GUARD CHINA IS ALL OVER YOU LIKE A RASH
