This is for Georgehifi especially but others can chime in.

Jmcrogan,

You are missing my point, and we are world’s away from Bo’s crazy Tru Fi claims or are saying we are the only ones out there that can make good sound.

If you read any of our posts we are pointing out to products that are pretty highly rated already.

Taste is taste, there must be system synergy and of course even highly rated products may not be one person’s cup of tea.

In the case of a Timex which I have owned, and a Tag Heuer, or a Mauric Lacroix both watches I own, there is no such thing as a watch which performs better ie kills another watch. In fact a cheap Timex quartz will take more accurate time readings than any $50k Rolex or Patek.

You purchase a watch as it is a beautiful bauble.

In the case of an audio amplifier or dac or whatever there can be good, better, and best, levels of performance. Over the years we have heard a lot of really expensive gear some of the uber gear is really amazing and is really performing at an even higher level of overall performance

System synergy still has to apply, we have a Light Harmonic Davinci which is a $35k Dac and yes it "killed" the lesser dacs, which we had in the shop at $15k and $25k, by killed once you heard the Davinci it was impossible to listen to the other dacs once you heard how much better the Davinci was in those areas that we value.

Performance and worth or value are too different things.

On direct comparison the T+A was way better than everything we tested.

We did find out that a $90k Boulder Mono block was better than a $32k stereo T+A amp with an outboard power supply, but that wasn’t a fair fight as T+A offers a mono block version which may be dramatically better we never heard it so we don’t know. The Boulder was better in certain areas, the T+A actually had better bass which seemed impossible considering the size and weight of the Boulders.

Hope that helps clarify. Why don’t you read the actual reviews and see for yourself. We would say that both reviews really do paint a true picture of this gear it is really special, again we are not saying it is better than some of the other uber brands, but if you look at Dagastino, Vitus, Boulder, and other similar models the T+A gear costs less and if magnificently finished with a fantastic feature set.

Go find some and see for yourself or don’t that is your call.

Khost are you a transistor designer?

Have you done any such experiments?

T plus A has why dont you talk to their engineers?

Could it be that if you use a higher voltage tranistor which is neccesitated by these designs that transistor run on that voltage rail runs with greater linearity than a lower voltage variation?

There are more variables then what you think.

I am sure you also believe that power cords dont work either?

You just cant run more voltage through the same device, it is called a high voltage circuit for a reason.

I think power cords are useful in that they do supply current from the wall to the gear (and my toaster, etc.), and any positive comments about gear from salesmen who carry the gear they comment about chews the fun out of the gum of any forum discussion.

I assume we are talking about MOSFET transistors on the output stage? Nothing new. Ideal for delivering extremely high current. Extremely high breakdown voltage. Low switching distortion and fail in a nice way (open circuit) which prevents too much collateral damage. Hafler started using these in the 80’s.
