Power Amp from ADA ( Audio Design Associates) a very high-end home entertainment installer/manufacturer. Looks and sounds very good indeed. Fan-cooled so set up for enclosed cabinet. Reportedly stable down to 1/2 ohm, so recommended for those difficult loads. Features; -Amp is very heavy, about 45-50lbs. See interior pix for Huge Heat Sink, Fan cooling, mosfets. I simply adore the sound of MOSFET amplifiers and I say this as a hi-fi reviewer who has lots and lots of high end and expensive equipment for review.and I wouldn't swap this for another amp without MOSFET output devices, in fact my replacement amplifier has these devices and it was not easy finding it, but so pleased that I have.

The front panel is a beautiful solid chrome plated steel item with the power switch to the left and another switch to the right hand side which disables the bar graph LED power meters, which is behind the perspex panel.  It has RCA signal inputs (no balanced inputs) and the speaker outlets only have provision for 4mm banana plugs.  The original feet are also missing, but will supply a set of sorbothane pads which also improves the sound quality as a bonus.

Amp Dimensions: 18-1/4 w x 17-1/2 d x 6h (Inches)  Potential to handle difficult loads. Back panel has outputs for 1/2- to -16ohms. I believe the reported power rating at 8ohms is 68 watts, but let me tell you this amp never ever sounds short of power.

The fan on the left hand side of the unit works, but there is the sound of bearing rumble, so depending on how intrusive it is, it is up to you whether you replace it or not.  My listening position is less than 4 feet away and the rumble has never bothered me at all, so I do not want requests for a refund as it is sold with this small issue, .

Collection from near Callington in East Cornwall, or I can deliver within 25 miles for the cost of fuel.

Shipping by courier is available but it won't be cheap as the amp is very heavy.  Cost will be £22.50 or you can book your own courior at your own risk.
