As always the question comes down to "why are they being sold so cheap"?

If you have the 80 to take a flyer go for it.

Note that it is not a tube amp but a hybrid, likely with a chip amp doing the heavy lifting. Nothing wrong with that approach

It seems awfully cheap for what it purports to offer. Note also that it is a hybrid tube amp so the speaker output I suspect is class D. There is a fan on the back, likely to be noisy in use. The knobs, chassis and other stuff look obviously cheap..

I would suspect that most of the circuitry is on cheap pcb and uses SMD components widely.. Perhaps not so easy to work on..

Postage is double what it should be - IMHO

If someone already had the iron and valves for a 4 valve amp then this could provide the case. Remote control, usb dac would add to the value. It looks cheap but no worse than some of my home build efforts..........

Postage here is through the roof lately so I was not sure what to think about the post cost.

WRT to your home build efforts, I bet they generally prove to be reliable - I'm not so sure about the amp discussed.

I purchased a very good Chinese dac a few years ago, a Zhaolu, and it continues to give its new owner satisfaction. It cost a great deal more than this whole ensemble, and I thought it a steal.. In this particular case it might be, but not necessarily in the good sense of the word..

The wise amongst the Romans said "Caveat Emptor" I have to agree..

Only because of the kind help of forum members.

My Chinese CD and DVD players seem to go on forever. My Cambridge Audio CD player ( British ) on the other hand is once again awaiting major surgery ( transformer this time ).

As far as the above amp is concerned I could be tempted by a used/faulty one going cheap on Ebay. Suffice to say it would be seriously gutted..........

With a fan i suspect it unlikely that it is a class D. Like the HCT (Dared, FatMan) likely a class B chip amp.

Mmmm......

My Hammond OT's ( from the USA ) were labelled " Made in Canada " but the box said " Made in China ". I myself have built units with Chinese boards and metalwork, tested them and labelled them " Made in the Usa ", and shipped to Eastern Europe!

Not sure how I would feel if my CD player was Chinese built....

Thank you all for your comments.
I have bought this amplifier will update when it will arrive.
For 80.00 (two week of cigarettes supply) good bargain I think, only one left at this moment.
Best regards.
