Anyone tried the "new & improved" Super t-amp ?

I know the smaller debut version had issues that were corrected only by some modifications. This new 'super' version is said to have fixed all that and then some. Its intended for the serious/sound quality concious listener. Wondering if anyone here has tried it with headphones and what their impressions were ?

Looks like a great amp for driving a K1000.

The case is nice. However, I got to hear it when a friend brought one over for repair. Volume pot front was not attached properly, leading to knob stem coming out of the pot, and very poor volume control. Fixed by tying the pot together with a small cable tie. Fit of board into chassis was poor. Still it may be an improvement over the original T-amp. I heard it as a bit smoother, but not much. I was actually happier with QC on the original T-amp, though, and that's not saying much.

Is there anything fundamentally different than the newer T-Amp and the older one other than the case/connectors? Cause the inside shot of the new one doesn't seem to reveal anything much different.

They could have put a bass and a treble knob. I read it's the same t-amp with a power source and some connectors.

well it appears the t-amp might not be well suited for headphone use afterall...

You are rigth, not just any regular headphone, but the AKG-K1K is perfect for it

The info on ultrasonic frequencies sounds scary, even with K1000s. Any thoughts on this.

Yeah, that doesn't sound like a very desirable 'feature.' I don't want to look like the guy in my sig.

The head exploding stuff is BS. You will damage your phones if you don't stop that DC offset though. The ultrasonic frequencies are not so bad IMHO as your brain actually filters them out if they are high enough in frequency, but seeing as the filter is designed for 4-8ohms I doubt the internal filter will work well for 32+ohms and leave some borderline frequencies in there.

The take home message is true. Don't bother using it with headphones other than the K1000.

When used with K1000, simply put 6-10 ohms of resistors in parallel.
Smoothes out the sound and eliminates potential DC offset and ultrasound problems.
