I like how this amp looks: STAX SRM-353S ??? #hpfes on TwitPic

Anything else Stax redesigned?

OK.

But they have nice headphones.

Still agreeing with you. Still equally as irrelevant in a Stax thread.

How dare you taint the Stax thread with mention of Grado? It goes against my morals to buy headphones with drivers that are held in a flimsy plastic/wood frame with glue from a hot glue gun.

Rudistor makes terrible headphone amp, their headphone meight be OK. I know everyone always juge before their it...

Yes.

Hadn't seen this one before. Very beautiful and it makes perfect sense for Stax to drop the SRM-300 in favor of a redesigned SRM323.

Indeed, worthy of a temp ban at least to mention Grado here.

Everything branded with Rudistor is an overpriced piece of shit. The electrostatic amps will also destroy your headphones as bonus feature.

I like the HP2 and the RS-2!

HA!

But then I also like the Triport and the NS1000 and the Float 2 and I'm not so keen on the K1000 and the HD800.

But keen of the HD800 avatar you are!

Got to have an avatar change from time to time! The HD800 is technically marvelous. It just didn't please me.

Who can be moar banned than Duggeh? The answer is none. None moar banned.

I think it is pretty cool though I'm dissapointed it dosen't electrocute you as a bonus feature...

woah, just saw that krmathis is running a beta22 into an srd7-pro and powering 007's

How exactly does that work?

And how does it compare to other SS stax amps? 717, KGSS?

Hi B22 is setup as a speaker amp.

Driving an Omega with SRD-7 Pro might not be the best idea, it will sound dark while loosing some detail ability as well. With a speaker amp like a Beta22 it might be better but then you are better off with a 717 or a KGSS. Custom transformers also work better than the Stax ones.

Does Stax have other redesigned amps coming? There seems to be some activity on that front with SRM-600 and now SRM-353S. Maybe they will finaly make something that can driver SR-007 properly like new version of SRM-727.

If you don't like flimsy plastic frames, the Lambda Series is not for you...

I will take any lambda frame you got over any grado (though more on a basis of sound than durability). The frames might seem flimsy, but tell that to my 30 year old SR-Lambda, which is still marching on.

I haven't heard anything but the use of ECC99's in the SRM-600 could mean a redesign of the 007t is in order. It is certainly a far better tube for the 6CG7 for this role and might give the circuit a much needed boost. Add some regulators to the HV lines or even a CCS for the output and it would be a very nice amp indeed.

I'm pretty sure the Lambda frames just seem flimsy and are actually pretty strong. I wouldn't test that theory on mine, of course... And like Colin said, I don't think I've ever actually seen a case where the frames broke. The headband, yes...

On the other hand, Grado QC is known to be... quite iffy. And even when the headphones do work, you have glue splashed around everywhere and the cables are twisted.

The frame is in reality pretty strong, partially due to the 1/10" thick aluminum baffle. I've owned countless Lambdas and aside from a few broken plastic cross sections there has never been any damage to the frames and I have the habit of buying badly treated sets to give them a new lease of life.

Compared to the faultless Stax QC. There have been some design issues on some models but a Lambda Pro made in 1982 sounds exactly the same as a unit made in 1990.

That is just not true.

This is a little more technical, but hope someone can help me.

About SRD-7 (normal bias) and SRD-7 Pro/ MKII Stak Energizer, do they all have the same specification in term of frequency response and sound quality, also do they have the same components inside, except the bias voltage different?

The Mk2 transformers have higher quality wires (PC-OCC) but the rest is pretty much the same.
