the manual doesn't say what tripath chipset its using.

I have an onkyo htr520 and this little amp sounds better. Don't know about the newer receivers. If you have an old receiver like mine and don't want to replace it...you can definitely get these to improve the SQ until you have enough money to buy better gear.

My onkyo receiver doesn't have pre-outs (wish they did) so I use the speaker level adapters connected to the speaker terminals of my onkyo receiver from guitammer and they work great. $7 each. I bought 6 amphony model 100 amps to hook up all 6 channels. You have to use the mono setting. I tried using both channels on each amp but it shorts the channels.

they remind me of the SQ from old tube amp receivers - natural, detailed, not harsh. for example, I can focus on a certain instrument or vocal watching a concert DVD and it sticks out. Also have noticed alot of details i missed in movies...so i am watching them all over again.

Whats better is that they don't overheat and turn off like the tube receivers.

I have had them on for several days and they stay cool to the touch.

They play really loud too. I use a reference level of 70db and can listen at that level. Its loud but instead of being annoying and harsh on the ears compared to the onkyo (without the amps)...with the amphony amps connected the sound is loud and clear (not harsh).

i tried using 3 amphony model 100 amps...

1st amp - for left and right front channels
2nd amp - for center and back channels
3rd amp - for left and right surround channels

what happens is - two of the channels will be mixed and one of the channels would be softer.

when i played the test tones...the right surround test tone would play on both surround channels.

When I connected each speaker to a seperate amphony amp problem solved.

Also if your receiver is like mine, if it has no pre-outs, and you are using the speaker level adapters too, don't forget to do the in-phase/out-phase test.

Are you sure the amphony were not in mono mode?
What you describe should also happen in normal stereo settings.

How is the little volume control on the amp?
I guess it also serves as an on/off switch. Does the amp emits a little pop when turned on, as did the sonic t amp ?

when i used the 6 channels of the 3 amps together, they were set in stereo mode.

using one amp to power each speaker, i set to mono.

I turn the volume knob on all amps to max. then adjust the level on the receiver.

Thanks

I wanted to knwo if it emited a "pop" on startup because I plan to use it directly on compression drivers, with an active filter.
I may still use a protection cap to prevent any DC offset, so this would take care of the bad parts of the pop...

i connect the power supply of each amp to a power strip...when i turn it off and on the speakers do pop.
