Sonic Impact T-Amp giant killer?

Gmood1...My 3 CarverPro ZR1600 amps do not have any significant "noise floor", but I did have to "diddle" more than usual to achieve this silence. Consider the following suggestions:

1..Use the ground lift switches as required.
2..Experiment with which AC power line you use, particularly with respect to what the source components are plugged in to.
3..Adjust the input sensitivity jumpers to as low a gain as your preamp will accomodate. I use 2.45vrms for my subwoofers, and 1.23vrms for the low efficiency MG1.6. (The factory setting is 0.775vrms, and there is also a 0.316 setting).
4..Balanced or unbalanced (20 foot) interconnects make no difference (at least in my setup).
5..If you think that the input processing circuitry (garbage) is a problem, and the built in bypass switches don't satisfy you, this stuff is easy to hard bypass with a wire.

I assume that you are not talking about the noisy cooling fan. Remote location of the amp is the only perfect fix for that, although there is a low noise fan mod.

The cost topic has come up before here. Mr Rossi states that his part cost is over $100 before his labor. Also there is no need for a pre-amp for the Clari-T whereas 6moons' best set up with the Sonic Impact was with a pre-amp.

both can be used as a one-input stand alone amp or with a preamp (the Clari T can be configured/constructed either way, whereas with the SI you just crank the volume control to maximum). myself i always prefer a high quality preamp for input switching and phono stages, and i suspect that the Clari T will sound it's best with a high-quality pre as well--not to diminish what i'm sure is great sound through a much higher quality volume pot in it's one input version. if you only have one source, then that certainly does change the comparative equation, and not in a small way.

in the process of constructing a much better quality power supply for the SI--a velleman K7203 highly regulated 3 amp PS kit.

Reading the consensus of the first owners.Most prefer the Clari T Amp without the additional preamp in the path.But it all boils back down to ...whatever floats your boat.Also as you've stated the number of sources you have to plug in will make that decision for you. At a time when audiophools spend $1000.00 for a pair of mystical cables..that look good more than anything else.The Clari T should be a very cheap ticket to audio nirvana with real science behind it.

Checkout this cool custom box for the little tripath chips
Tripath/Sonic Impact chassis. Even for the yuppy audiophiles..you have to admit that chassis is a winner!

oooooooh man, that is nice. thanks for the link!!
