I use it for 5 months, I am fully satisfied. Sober, discreet but very effective. It is a bridge to 4 ohm sub, and is! (Active filtering by a behringer cx2310).

The buttons are notched trs enjoyable to use.

I bought mine on ebay for under $ 100 with shipping, c'tait a good deal. Inter-m as a brand known mostly audiophiles the argus spcialiss sites do not m'apparat trs INTERESTED, I briefly considered buying a new appliance for few euros more. Often the port is available for a purchase of that amount on a commercial website.
With a little patience, you can turn to one used no worries of reliability. Any fawn, even a new product Submitted a good value qualitprix trs.

In my current configuration I am limited in quality by my sub orient "car audio" (registered air SERIES O2) but a lot of clean and powerful bass.

If c'tait again, it would be "yes" without hsiter.
