REACTIONARY POST.

Even though we discussed the sarcasm, EdT apparently missed it somehow.

"Also, digital is bad because it isn't analog. That is just a fact."

That's SOOOOOO going to be my sig...

No I didn't, I'am just a T-Amp lover and defender of the faith !

Is that platonic, bonding man-love or some girly tongue in it's ear type t-amp love?


just wonderin'....

This is the review which made me buy the T-amp:

It is quite interestin to read!

I can tell, EdT, and I also like my Super-T amp very much, but, fellow T-amp fan, you still did miss the point here - raif's post was making FUN of the people who were bagging on the T-Amp! He himself was not bagging on it AT ALL. Yet you attacked him as if he had.

I know sarcasm is often hard to pick up on when reading internet posts. But raif is on your side, EdT, and you capped on him for it

In any case, the overwheming opinon of people who have actually USED a T-Amp seems to be that if used within it's limits, it's a very good little amp. Mine certainly drives my B&W DM600S3's just fine, given that I sit less than 1M from them.

Agreed, my self-modded T-amp sounds very nice for what it is. At low listening levels I have no reservations about it for the price, it's only when at medium or higher levels I begin to notice lack of dynamics but then I have it in the garage with mediocre efficiency speakers.

I must now point out a myth- it is inferior to use a SLA battery, unless it is still followed by equivalent capacitance as on a well endowed traditional PSU. Battery impedance is much higher than a decent AC-DC PSU and with the *decent* AC-DC, a minor bit of noise is a non-issue, these Class-T amps reject the low frequency noise quite well. It's like selling snake oil but this oil burdens the owner with constant hassles to charge up the battery and replace it every few years. That is, unless you want it portable.

Where did the crazy myths about batteries for solid state amps start anyway? Probably with people using only a crude unregulated supply for the comparison, but with the T-Amp there is no need for this, even the venerable LM317 can handle the current asked by the T-Amp at reasonable listening levels.

To TimxSally, please use the forum search feature to find existing threads instead of asking if anyone has heard of "X". It will bring more info than would be represented at this later date, and bring you up to speed for a more informed conversation should a new thread be needed to cover anything missing from the prior threads.

They work fine with headphones, but like any amp you would have to design or modify it to suit the intended load, and of course what has already been mentioned that with the T-Amp (and a few other SI amps) you can't have the L/R ground tied together, would have to recable many headphones, and to calculate a new output stage to keep the high frequency in check, or put a parallel load on it so the amp *sees* the ~8 Ohm the original output stage was engineered for.

You don't have to do such rediculous things for other amps. Linear SS amps and other Class D amps like the UcD amps are independant of load. And also the grounds can be shared on those amps.

The T-amp actually wants to see 6 ohms at the higher frequencies. Speakers and headphones alike have a varying impedance load depending on frequency, so with the T-amp, you won't have a flat response.

It's do-able, you just have a mental block.

what are you talking about? yes, if you remove the output filter it will become load-independant, but you will be breaking the law.

My own "T-amp" can have shared grounds, but not the Sonic Impact T-amp, since it's already bridged.

I'm talking about it being do-able, because it is. I never wrote to "remove the output filter".

If you don't want to do it, ok, but that's different than trying to arbitrarily mislead about it.
