An about $500(US.) cheap tube integrated amplifier, caused by manufactured in china. My friend give to me for testing it. So, i connect it with following component1. 3A Audio Design Loudspeaker-M2 Generation 2
2. California audio labs--Alpha D/A converter
3. Marantz LV-300 as CD-transport
4. Connector
Discovery cable twine model : Alpha to Zell3
Audio Alchemy fiber optic link from LV-300 to Alpha
Eagle speaker cable
Vocal is the first thing it do well: clean, powerful and very live, like general tube style. Other sound incluced bass is also powerful and clear. Image and sound stage is okay for not too much musical instrument such as very big band classical music but it's not too bad !(but think about its prize-$500, this is can be forgotten). But i recommed that it suit for program(CD or D/A converter) and connector which not have too much bass reproduction. The time i test it, i have DAC-MAN(Audio Alchemy) which bass is not so good(too big and Blur) It can overcome the competitor which is twice or more prize.
Trial it
I give it 3 star rated with no regarding to the prize, and 4-1/2 star when look at it $.
Average rated is so 4 star
