Paralleling the tubes with half the output impedance correct? Should be a positive improvement.

You got it.

We're talking about a gain of 2... 4 balanced. Why do you think a balanced M3 would have a better go at it than a balanced beta22?

Now, I'm not sure if all of these gain ratings are directly comparable, but if they are... The K340's are not going to be happy at the levels I listen, given my experiences with the 10 gain dynahi and assuming that a gain of 4 is 40% relative to a gain of 10 being 100%.

Hmmm... I wonder what the gain on my amp is. Any way to measure it?

I'd be willing to bet that the beta22 could do a good job of driving the k340s as well. It's all about the ability to deliver current. But I am just guessing, as I've never been in the same room with a pair of 340s that I'm aware of. But my M3 is capable of delivering 7 watts or so into 8 ohms, so I would be shocked if it couldn't drive the akgs. Gain is only part of the equation.

Yeah, the voltage swing part right? That's a pretty big part of the equation with the K340's. I'm positive that both amps can drive the K340's, in fact I've heard a balanced M3 and it did a great job, but I don't believe it had a gain of 2. I'd be worried about having to max out the volume and having no breathing room for adjustments.

Maybe if Thrice is around he would know what the gain setting was on the balanced M3 that he brought to the first national meet...

Speaking of, what is the gain setting on your balanced beast from Toole?

selectable 1,2,3,4

That's the amp I've been talking about. balanced m3 with a mega power supply. So mega it melted the power supply caps, so that's being fixed now

It was selectable...between 2 and 10...so you probably had it on the higher gain setting...so did I since I was driving K1000 from it.

Seriously, if we want to end this debate I'll send my K340s for Stephen to use for a couple weeks with the betas he's building. I don't expect to have the first of two betas I'm building done that quickly.

Bring them to DC meet in oct

Actually that would be good...are they wired for balanced operation as well?

Not currently but that's probably easily remedied.

If someone wanted to send a balanced pair my way I can let you know immediately on my Balanced Beta 22 (gain of 2, 4 balanced) how the K340 fairs. But I'd be willing to bet that a higher gain (say 6+) would be better for those headphones.

Do you have the stupid 4-pin jack on your amp?

yep, but I have an adapter so I can make those poorly thought out and highly inefficient dual 3 pin XLR plugs fit. You know, for the people who don't posses forethought.

so you had to send it back?

I gave it back to colin the yesterday. He's gonna change the speaker outs to XLR and RCA preamp outs for me at the same time.

yep, but I have an adapter <snips a bunch of bs>

Well, then I'll inefficiently reterminate the 340s this weekend if I have chance and send them to you, wise guy.

hopefully it won't take another 2 years.

He's bringing it to the dc meet.

whatever....asshat.....OH no he DIDN'T!!!!!!!

Well, Nate, I did go HA-2 / HD600 to HE60 / Blue Hawaii... think balanced HA-2, but faster, with the same overall sound signature, kinda. So, this path has been tread before.

BTW, I paid $1450 shipped from Eurpoe for my HE60 / HEV70 with new earpads a year ago. NO intentions whatsoever of selling, even with the Lambda Nova in reserve.

well, it depends: you'd be eligible for my sympathy if you got run over by a herd of elephants.

Mama? Is that you over there?
