Some very nice looking amps, would love to listen to one. The 6V6 is w/ the 7591A my favorite tube. If you have a chance to listen to an old 60's black face Fender Champ or a 60's Ampeg Reverbrocket or Jet you will hear what I am talking about.

Skylab: The Audio Space range of amplifiers are designed, engineered and tested in Hong Kong, assembly is of course in China. Audio Space have a strong following in Japan and are quite well respected having being featured and reviewed in the Japanese "MJ" magazine (Hi-end audio journal mainly on tube gear) on many occasions.

Cool. I sent an email asking for a review unit - let's see what happens.

^^^ You may wish to also check the latest update I posted in the Yarland P-100 thread where I list rankings compared with some other amps. I have also made a note that with some of the tube amps, the headphone type and impedance does have an overall bearing on the low level amp noise (call it very low level tube hum) detected and the AS-2.8i is no different from other tube amps. Some headphones are just terrible with any tube amp, period, I think it has to do with the impedance of the cans used.

They also have a 300B version which looks very nice!

 

[Skylab]

Agreed on all that - tube amps require a little care in headphone matching.

^^^LOL, I'm up to my eyeballs in tubes and amps and need more rack space! BTW have you seen the G&W Tsing Hua University head amp which looks like the P-100 but slightly higher (also tubes and wood face plate with gold knobs). I've been trying to find more details on the web, but failed?

Really nice amp there. From the 9 types of 6V6 I have tried so far, I have found the best to be:
- Radiotechnique RT 6V6G (most balanced, warm and sweet)
- JJ 6V6S (the only new production tube I've tried with Sino: powerful, extended and strong mids)
- RCA 6VGgt (very warm, full, great bass)
- Ken-Rad 6V6gt (a bit like RCA, less fat)
- Sicte 6V6 (also warm, creamy, but not as full/thick as RCA; more refined)

The only brands that I didn't like were
- the stock Sino
- Sylvania (sounds honky-farty, not very extended)
- Mullard (probably rebranded... sounds muddy)

Anyone tried NOS GEC or Mazda 6V6G ?? They are supposedly the best

I have a pair of beautiful NOS GEC 6V6G's I bought for the MP-301, but can't use since the sockets are too close to use the G versions...grrr...

^^ Thanks for the info., this will assist me in tube selection, many thanks.

^^^ Any reply yet?

 

[Skylab]

Nope. I'm guessing they either are not interested, or did not understand my email due to language issues...

 

[Stevesebastianb]

^^^ I don't think it's a language issue, more like because they are a quite well established brand they may not have any interest???

 

[Skylab]

Probably. If they don't feel they will benefit from a review, for whatever reason, they won't bother. So either they don't want to risk the possibility of a negative review for whatever reason, or don't think the hassle/expense is worth it.

 

[Stevesebastianb]

Oh well, maybe I will write something up on my blog using my unit as a review sample.

Skylab, have you tested the MP-301 with speakers? Also, would you say it is the best 'tubey' tube amp under $300?

I'm looking at the MP-301, Qinpu A-3 and the Eddie Current Lunchbox. I want a characteristic tube sound (even at the cost of losing some accuracy/transparency) and ability to drive speakers. What would you recommend?
