Your experience as Yamamoto owner?

Hello.

I'm interested in Yamamoto amps, likely the 45-based A-08S or the 2A3 A-011. There is very little info I found here and elsewhere online about these amps, and asking Yamamoto thru e-mail I have gotten no answer. Makes me wonder what to expect in terms of post sales service if I don't even get an answer when asking towards a sale?

So wondering what's the experience of the owners out there? Do you contact Yamamoto or someone else?

Anyone knows where to find user manuals online? Specifically I need to understand what kind of speaker impedance these are designed for, as there is only one set of speaker outputs. Or maybe there are different taps internally for different impedances and one can manually set it?

Thank you!

The 6moons review is here very extensive with great pics:

And the link I sent you earlier was from the German importers website which is quite good. The previous US importer was I believe Venus Hifi and I think they are now out of business.

Thanks guys.

I'm intrigued by the lack of owners and threads about this brand. I was aware of Srajan's reviews and those also fueled my interest. The few things I came around sound appealing, but the fact they are so few are also making me pause.

Charles1dad, thanks for the name! I knew there was another rep back in 2005 when Srajan wrote his articles and knew they were out of biz, but didn't know there was a new one. I will get in touch.

I was hoping to be able to discuss with the manufacturer because my intended use is a bit different from mainstream (mainstream in the context of a niche like flea-powered SETs, that is). Will see what Ocellia has to say. Still, I can speak with Elina at Lamm, for example, when I have a question...I was hoping a similar situation when dealing with another niche manufacturer. Oh well.

FWIW, I'm building my own 4-way active speakers, and plan to use a pair of Yamamotos to drive the tweeters and midranges directly. Tweeters are 102dB/W and 5ohm flat impedance. The midranges are TBD, but a couple 100dB/W options and some are 8ohm and could do one at 16ohm. With only one pair of speaker outputs in the Yamamotos I'm not sure what impedance they are expected to be connected to. Hopefully the North American distributor will know.

One other suggestion. . . not specifically about the Yamamoto, but about your design plans in general. . . You could contact DejaVu Audio outside of Washington, DC. They make their own line of 45 and 2a3 SET amplifiers and are highly knowledgeable and willing to customize.
