Very handy (even if the Power unit is kind of the same size than the unit itself), but a little weak
80W Solid State per channel are not enough for live performance ( at least to me )
On top of that the pairing with my Atomic Amplifire is not easy.
Despite of my efforts, I couldn't achieve a credible replacement for a Valve unit

The rucksack

Christoph6128, 11.09.2016
With 50+ you have as a hobby-musician, who haul his stuff himself, has to build up and dismantle besides the sound a decisive criterion in the equipment selection, namely the weight. This small power amplifier has replaced a Koch ART4502 in my live rack (Marshall JMP1, G-Major2 and an amplifier). As with the cooking product, you have the choice between stereo and mono operation and the weight savings is a real argument. The live sound on the stage is not worse, the power is there and reserves are still without end. In normal setup with 2 guitars, drums, bass and vocals, both volume controls (JMP1 master and power amplifier) ??are still clearly before 12am and thus the volume - even with loud drummer - is completely OK. I usually use a small Thiele box with a 1x12 Jensen Alnico Speaker (weight! :-) The option of a second box I have so far also not needed with larger occupation (with keyboards, more singers) or in larger halls or outside. A real sound difference to the Art4502 or a Marshall power amp (Valvestate 8008) I can not determine. Tube amplifiers fall out for me because of the weight anyway. In direct comparison with the Art4502, the small ISP is clearly ahead. Above all, the unpleasantly loud fans of the Art4502 are completely eliminated. More than one volume knob is not needed on the power amp.

I would only wish that there was a version with an internal power supply in the full 19 "range, which would make the rack installation again much easier, but the accommodation of the external power supply is by the side mounted rack mounts no problem.

A reasonable attachment of the power supply to the rackmounts might be a useful compromise. So it's just with cable ties or Velcro. OK - an ON / OFF switch might not be bad, but I simply switch the power with the switch of the Rack PDU.

I am very happy with the little thing. The total weight of my 3HE gig rack is 12kg (Gator Case, with all cables, PDU and covers) and the sound is top!
