Default 500W of ICEpower for USD$100, deal or not?

In several retailers there are selling the closeout VOCOPRO FeatherAMP 500W for under USD$100.-

That amp uses the ICEpower 125ASX2, which can be used in stereo (125wpc@4ohm) or BTL (450w@4ohm).

The amp also comes with gain knobs, a design that can be used as a plate amp, a 1/8 TRS pre amplified input and also balanced input.

The VOCOPRO company is California based, so I would assume they used genuine ICEpower products.

I am kind of wanting to buy it to power my Auralex bass shakers or maybe another subwoofer.

So... is it a good deal or not? What do you think?

Looking forward to your replies and comments.

Well a bare 125ASX module is typically app. 120-130 USD, so on that basis it's a pretty good deal I guess.

In the specs it says it use a Class D ICEpower amp:

And from the numbers (120wpc@4ohm or 500w@4ohm) the only amp module that fit those is the 125asx.

I already bought one... now a few days until receive it (I dont live in the US). I will upload internal pics.

If the buffers are suitably transparent this is a very good deal. I built mono BTL 125s this spring and just the IcePower and differential buffers were $170/channel.

What kind of buffer you used? Do you have pictures?

I've read ICEpower modules requiere a buffer for FR usage, but it's not necessary for SW duty.

As soon as I receive it I will post picture of the innards, and impression of the SQ.
