A question about "matched pairs" if I may. Do they have to be from the same year or are they tested to match and if so, how is that done?

 

[slwiser]

My understanding is that they should test as within a certain range of each other.

Ah, ok thanks. I bought two pairs but saw in each pair the tubes were 1 year apart. Made me wonder.

For the first time I just plugged my HD800 into the Yamamoto HA-02.  I have been using the SPL Phonitor before.
 
Oh this is going to be fun for you when you get the Yamamoto...
 
Using my Lavry DA10 and computer files via USB Audiophile and JRiver music player.

I will be using it with my computer - Audirvana Plus player - DA-200 via USB - Yammy.

 Tell me more!

I think there is some magic in a SET tube amp that is done right and the Yamamoto is a SET amp and done right.

I always get confused about the types of tube amps. I read there is SET and OTL, but OTL is SET sometimes as well?
I wonder what types there are exactly and how to keep them apart.
And most important, what the sound differences are.

Thanks for the link! I'm printing it out, will be a good read for tonight. Should clear things up a bit for me.

 

[AppleheadMay]

Hmmm, I still see that there is SET, OTL and SET OTL (WA2 for example)
What exact type from that Article is the Yammy?
And which headphone amp would be pure OTL? (not DIY)
Does pure OTL mean that there is no transformer at all? I see the Zana is OTL but has a transformer.
 
Confusing ...

 

[AppleheadMay]

Would this be a pure OTL and could it be any good?

Just bought my Yamamoto.
 
Oh my holy god of amps, how I love the way this amplifier looks, and even more so how it sounds.
 
It's like, my life is satisfied!
 
Thanks to Slwiser for his advice!
 

 

[AppleheadMay]

Yep, a really good amp well worth the price indeed. 
It does great with the HD800 as Slwiser recommended me to try and it's an amzing performer with all of my ATs as well.
The soundstage is quite a bit bigger than on my SS amps.
 
I even got me 2 pairs other tubes to try out once these are burned in as well as tube dampers and some gel pads for under the feet.

 

[lemontree5544]

So, my DAC (Stello DA100) recently decided to die on me. Just wondering, does anyone have any DAC recommendations for the Yamamoto?
 
I dont exactly have a budget, but I guess I'm looking for low - mid range DACs. (1000ish and below).
 
Preferably one with USB input ^^.
 
Any help will be appreciated!

Yammamoto makes two dacs, but they're quite pricey.
Some nice reviews on 6Moons about them.
I hear very good things about the Onkyo DAC 1000 at $700 I believe.
100V so maybe you will need a step-down.
 
And I guess you mean USB input?
