Dear Chings:

Does anyone used these mono blocks before ? Are they good amps? I am thiking of getting a pair.

many thanks in advance for your advice.

Generally speaking, the smaller the number of power tubes used per channel, the better the sound performance. It is because it is difficult to match those tubes used. 1 or 2 power tubes per channel is preferred.

Thanks Ching.

But more tube meaning more power, don't you agree?

JA30 uses 2 tube per channel, JA100 uses 4 tube per block. The output is 30W vs 80W.

In that case, wouldn't the KT-150 gives you even more power and only 1 pair of output tube per side ... :-)

I'm a JA80 user and very happy with the performance of it.

For tube amp, you need a pair of high sensitivity speakers(over 90 dB). So tube amp output power is not important.

Not really true fewer tube gets better sound performance. Sound quality mainly determined from its build quality only! What I really concern is, Jadis no longer uses point to point hand wired technology, they use circuit board to build their products already! But I am not sure is it just a rumour?

My 2 year old JA80 is hand wired.

I am also a JA 80 user. Very nice monos.

Hi Georgebush,
Would like to know if you are using the original tubes ?
Pls PM me to discuss.

Does anybody know if we can still buy JA15 monoblock?

I would say JA80 is good and heavy enough. Unless you have a neighbour who is as strong as Arnold Schwarzenegger, don't get JA100. They are too heavy.

I am also a JA 80 user, very satisfy and no longer trouble
