B22 or EHHA for HD800?

Dec 27, 2009 at 10:47 PM Post #2 of 47
Both amps would do great justice to the HD800. Both are top quality amplifiers and choosing between them would come down to personal preference.

The advantage for the EHHA is that it costs about half as much (parts cost) to build compared to the B22. The EHHA also can be tuned to your ears by playing with the amount of feedback by just switching a couple of resistors (mount them on sockets).

I’m yearning for a bit more pizazz than my current balanced β22 is giving me with my HD800’s, although the combo is reference and it’s fairly neutral, I need some fire and passion in my music, it’s starting to wear thin. I’m hoping my balanced EHHA (soon to be completed build) will live up to sachu’s raves

lol..look forward to your impressions john..I have no doubt that you'll be glad you built the EHHA.

With my budget b22 coming in at about $350 are you saying I can build an EHHA for like $175

? Only kidding of course, that beta22 was built specifically to be low-budget but appears to compare well against "real" ones.

I do concur w/sachu about this being personal preference. In addition to having a reference/pure sounding amp I also like having an amp around that allows some variability in sound signature (e.g. choice of tube).

haha..seems since I bought my EHHA kit last year, the prices have gone up on the EHHA kits. Its no longer a 110$ for a stereo kit but rather 165$ the kit does come with Amperex Tubes now which alone are worth about 50$ a pair. Jeff has run out of the 5$ per tube stock he used to have..that was just an insanely good price on those tubes.

So the price gap has definitely closed by a big margin. Just getting ready to put in an order for 2 full ehha stereo kits..one to replace the set i trashed and the other just to have on standby in case i bugger up again.

just flip a coin already =.="

You either have enough knowledge to decide which is superior or you realize they are both dependent only on your budget.

Our opinions of their sound means nothing

FLIP A COIN BRO.

john,
i hope you're enjoying the the EHHA build. Alex designs wonderful amps. i've not heard the HD800, but maybe it's not your cup of tea? "neutral" is a coloration just as "musical" is. it's about the music/performance, no?

You have a boring source. I've heard your combo and it was a bit on the dull side of life. It didn't have great dynamics and depth and it's because of your DAC's output stage which is flat. (The wrong kind of flat.)

Mine used the IVY thing which isn't great in my opinion.

I forgot to mention that. I don't even know if it was single ended or balanced output, so forget my comment altogether.

fishski13, you may be right... let me elaborate, the HD800’s are apt with dynamics, transparency and generally most other traits of a good system. What they lack is ebb and flow and the context of phasing or linking passages together, whether they distract your attention with something else I can’t answer or put my finger on exactly what it is. I do have a suspicion that the slight lack of upper bass and lower midrange could be the key, and it’s probably something that I value personally with my system and at the moment it’s not quite right for me.

Oh dear, your in for a long wait, I’m very slow at building.
Ferrari, a very talented chap has built both, he may chime in...

I was going to say the same thing.

John, perhaps you should try some other DACs.
