I don't think so... BASH was the analog equivalent, used signal delay
and power supply steering to increase the efficiency of an otherwise
typical AB amp design.

IIRC, Blade Audio has been/was using Tripath stuff in the early 90's. They
had the BASH circuit as well, but I seen to remember reading thatthey were a
Tripath design. I could be wrong.

We're just finishing the development on a 1,000 watt 2-channel Tripath
amp... it also has programmable features that can be set using our
handheld Bitwriter programming tool.

Clarion and Arc Audio have both shipped Tripath models for the last 2
years or so, Alpine has had a multi-channel Tripath model in the past
and US Amps also shipped some Tripath stuff as I recall. And, the
Blaupunkt amps that had the colored plastic covers were Tripath designs.

It looks like Visonik and MA Audio have variations on the Class T Tripath
full range design. Also the PG Tantrum 1200.1 uses Class T Tripath but


it


is not a full range amp.

Has anyone used or seen any of these in action? Or more to the point any
Class D/T fullrange amps?

I recently hooked up a Class D sub amp and was quite impressed with its
power output vs. system drain. With the Class A/B amp I had running the
subs before, you could tell it was sucking some serious power at higher
output (dimming of the dome light at idle). The greater power output of


the


Class D and I only experience a slight flicker at idle with even higher
output and more pronounced bass ouput (attributed to the additional power
output not the given design). Plus the amp doesn't even get warm, while


the


A/B amp used to get quite warm.

They are claiming these fullrange Class D and Class T amps can give the


same


performance if not greater than an equivalent Class A/B design. Any
thoughs? I like the fact of the lesser strain on a vehicles electrical
system and was venturing to look into one of these.

This is not meant to start a flame session, just some constructive
discussion.

Thanks,
Ivan
