Genzler Magellan MG800

I've been using bass amps for decades and the poor old bass player has always had the heaviest and bulkiest setup in the band!
Not any more!
This class D (switch mode) amp is light weight, mega powerful, and looks absolutely pristine.
Oh dear! - it's got a fan! - I didn't realise before it arrived! - but it is VERY quiet - truly madly deeply honestly!
There is a simple trade off. With no fan (and I was seriously considering one) then if it overheats it has to shut down! - Silence! - in the middle of a gig! - do you really want to risk that ?
The controls are simple and straightforward - and I am used to a graphic EQ and a parametric on the same amp! However, these controls are more than adequate. With everything set at 12-o-clock (and this is a very good test) the amp sounds clean and powerful. I suppose I'd better add NOT the contour control - set this to minimum. I don't like either of the contours, but that is entirely personal preference.
What's with the 2.67 Ohm setting ? Well if you do the maths, that's 3x 8 Ohm speakers or cabinets together.
I was originally intending to use an 8 Ohm cabinet, but couldn't get the right speakers at the right impedance. No 16's with the right frequency response, no 4's in stock, or not at the power rating I really wanted.
Eventually I opted for a pair of 8 Ohm 500 Watt Eminence Kappa Pro-10A. That means I could theoretically hit them with 800 Watts into their combined 4 Ohms. All theoretically within their limits. There is more than enough EQ available with the controls on the front panel to get just about any sound and I'm not one for turning everything up to "Number eleven".
Not really given much time to the Drive channel.
The 2.67 Ohm setting on the back means that I can add one more 8 Ohm cabinet - A 15 inch LF driver! - without any instability. The sound on 2x 10 inch Eminence is perfectly ok to me, with DI to the main desk.
Update:
I have now tried adding a 1x15 bass cabinet, and as expected, the low frequency response has increased. The overall perception is that it is "Louder" although the physics suggests that 800 Watts is still 800 Watts.

I use this amp for all styles of music and it is so dynamic. I you want a nice tight round bass sound, then this is the amp for you. It's very powerful, so is great for big & small venues. If you like a nice tone as well as a strong bass thump behind it, again - look no further. The drive section I don't really use all that much, it's not really there for distortion, it's seems to give you that vintage tube sound more, if you like that sort of thing. I'm really pleased with this amp, it's light, looks great and solid too.

Der Amp ist absolut TOP verarbeitet, das bin ich schon von den Genz Benz Amps her gewöhnt, die hatten auch schon höchste Fertigungsqualität.

Die Bedienung mit den 2 Kanälen, dem parametrischen EQ und vor allem dem Contourregler (mit 2 Modis) machen die Bedienung sehr flexibel, aber trotzdem einfach und übersichtlich. Mir ist es wichtig, nicht zu viele Knöpfe zu haben.
Der Overdrive Kanal ist sehr musikalisch und im (Live-)Sound mal echt zu gebrauchen.

Der Sound könnte im Grundsound vielleicht etwas mehr Bässe vertragen, weswegen ich hier 1 Stern abziehe. Aber gut, das kann man locker mit dem EQ nachregeln... und ich hatte davor nen Mesa M6 - vielleicht bin ich da etwas taub geworden :-)
