Given my life these days, it is unlikely that I can attend a meet. I will however take a look at the used units. There is a lot of variability in configurations and build quality.

Thanks

I took a look and none are really what I am looking for.

Hi,

To anyone following this thread, I opened a poll over in the headphone amp forum now that it has come down to two choices:

- AMB Audio: 4-channel Sigma / Beta 22 (made by YBM)
or
- Donald North Audio (DNA) Stratus 2A3

You can vote here...

I do no for myself the Gilmore amps are more transparent and in a word unforgiving compared to  AMB amps.  The βeta-22 and the M^3 that I have are colored by this I mean more tilted toward the bass.  The M^3 more than the βeta-22 but both more so than lets say a GS-1.  

 

Sharhrose has lived with these amps for a while now.  I'll put $$ on him that he can pick out the Dynahi in a blind test.  I'm sure I could do the same when I had the GS-1 and the βeta-22 together at the same time.

 

Whith that being said.  YES it is hard as heck to source the parts for the Dyanhi - I think I got some of the last boards from lil kight.  I also think Kevin is coming out with another desgin called SS (Super sym) something?     With onboard heat sinks in stead of offboard

 

Hey prep, I've written a lot on the Dynahi vs Beta here and elsewhere. I personally prefer the former as you know, though both are my favourite all-time amps (including the Apex P/V). No doubt there's a difference in SQ and it's easily noticeable. They each have a distinct sound.

 

The Beta is more thermally efficient and stable I agree with Joey there. I wouldn't use either to power speakers so that's a moot point, but if you want to know which one powers the K1000 and HE6 better, it's the Dynahi without question.

Thanks Shahrose. I'd love to get them both together and have a listening comparison as my suspicion is still that they should be indistinguishable. A well designed amplifier (IMO) will not have a sound sig at all. Both of those are modern, SS amps, designed for neutrality-they ought to not sound like anything.

In an absolutely ideal world, yes. But realistically, this view is too simplistic considering their differing designs regardless of what very basic measurements say.

Well Louie,

 

Going on by that.  My Balanced M^3 (two boards) should sound the same as the B22.  Is that what your saying.  If so - That's not the case.

I am guessing under the same logic, so should my Grace Design m903...:-)

Thanks to all of you for your comments.

I have made a decision and an order has been placed.

In the end, I went for the fire bottles.

I ordered a DNA Stratus 2A3

Not a bad call at all.  Now to see if you can continue on the path without straying into other amps!  I like 2a3 tubes, they aren't too expensive and the current production ones did not disappoint.

Don't ignore the Luxman P-200. I have lived quite happily with it and the HD800 for the last two years.

you will be very satisfied, that's for sure.

Forgive my ignorance, is the 2A3 a amp design blueprint that manufacturers use? Because I've found two, Eddie Current 2A3, and DNA Stratus 2A3. The only similarities my novice eyes can see is they are both tube amps.

post #135 of 172
A 2a3 is a type of power triode output tube capable of driving headphones and efficient speakers. Other popular output tubes include the 300B, EL84, EL34 to name a few. Each has its own electrical parameters and sound style.
