Yamamoto Sound Craft HA-02
Jul 14, 2010 at 8:21 PM Post #1,263 of 1,351
Earlier in the thread it was suggested and confirmed in some instances that cleaning the tube pins will subdue the background noise. I think Java also suggested once that upgrading the power cable and interconnects could also help. I don't own the Yamamoto so I don't have any personal insight, but I did read this entire thread last week with a keen interest in joining the owners club.

I couldn't resist in trying the little Yammy with some speakers. Looking for some small, (relatively) high efficient speakers I tripped over some tangband horn speakers - the D4-1. - http://www.tb-speaker.com/detail/1208_03/D4-1.htm - The sensitivity does not look really high, but the 88db/W work for me in a 20qm room.
It sounds fine with a very detailed midrange, a firm but not very deep bass and a smooth treble.
A bit of fullrange - SE tube amp magic.
Cheers

Please, tell me, what could be causing this?

Have that has well, but when I switch to the unused input there is almost no hum on my HD800 even with volume knob turned to max. on the Yammie. When I had the W1000 there was almost no hum, if I remember correctly. Changing interlinks does help a little. Switching left and right tube brings the hum to the other channel. Changed both tubes, still the same problem.  Cleaning tube pins did not solve it unfortunately. There is only little hum with my Havana DAC compared to having my YDA-01 DAC connected. Can it be I have some DC current looking for the easiest way out, does that make sense?

I would like to add that this amp is much more beautiful in person than the pictures show.  The build quality is tremendous, very Japanese in the attention put into the craftsmanship and fine details.

Hello everyone! Guys, i'm asking for Your help!!!! (read as S.O.S:)) 
I've received Yammy a few days ago. It sounds great, of course... But it has a very annoying low background noise in the left channel (even without connecting to a sound source)

Please, tell me, what could be causing this?

Had a similar problem, and changed both tubes ... , the left channel tube was the culprit, in my instance as well ...

Always good, and AT woodies, are a good match ... :)
 
Still with my Senn 580's, the 600/650 Senn's didn't warrant the price of an "upgrade" and the 800's are just to darn expensive :frowning2:
 
A friend, has a pair of Senn 800's on his Yamamoto HA-02 and it is magic ...

I have tried it on the last weekend at tube-audio festival in Tokyo.



It has connected with iPod. The mid to high is sweet and sound like other Yamamoto SET amps, I like the sound but I hear slight hum noise from the demo machine.
The tube is Western vintage 408A as Carl san said. the price is 88000 yen. I am not sure the availability in US.

Other headphone amp from the show is softon model 6. it has build in USB-DAC and use one 6922(6DJ8). the price is 47000 yen.

wow thanks sasaki, I'm going to try to get some more info on the softon

I did try Yamamoto with HD800 but i would says is not briliant as i expected. I own HD650 with a great custom cable recently invented by Malaysian DIY member. This combination with Larvy Da11 even powerfull than HD800, I would say HD800 is better in Larvy Da11.
 
Anyway back to topic of Yamamoto, i been heard this amp past two years ago with my w1000 which is my second woody. Is a very good amp to pair with but that time i didn purchase it cause i still hunting ATs discontinued woodies line. Recently i manage to get W2002 deal. So will arrive to me also...Market price is increase either..$1.25K for a nice W2002. Yamamoto can sings all my ATs woody well even i think to get the "Floating mount" which will make the sound more transparent..

I am, myself, very sorry, I did not manage to buy a pair of AT W5000's before they discontinued, as I thought them very good, and different enough, from my Senn's to warrant purchasing ... <sigh> Life, unfortunately dictates I spend my money elsewhere, am going to have to make it a "project" to aquire some better headphones ... , and save the required funds very carefully ...
 
Unfortunately don't have access to a Lavry DA11, really wouldn't mind ... :)

i guess you still can find a brand new unit for W5000. Nice to collect. I will settle down this unit after i get my W2002...

Well, I was just over at Venus Hi-fi and had the unpleasent surprise of a price no longer reading $995 but rather $1200. Does this mean that Yamamoto-san has improved/changed the amplifier in some way (which seems unlikely after reading through this thread) or that someone just wasn't making enough of a profit? If no one here knows anything I might shoot an email over to Venus Hi-fi. In the event that this just is a price hike on the distributers end, is it possible to order this amplifier direct from Japan? I remeber someone doing so earlier in the thread, but don't recall if it was an international order. Either way this is very tragic news, as my dream system keeps becoming more expensive.

Anyone care to comment on how the Yammy sounds with T-1s or is it just an AT amp?
Click to expand...


T1 is not suitable for this Amp. I tested this combination. AT still the best to pair with. Why is so good. As you know AT headphone has lot of colouring so Yammy is like to make it more beauty of the colour.
