    Any suggestions for a Class D power amp? I'm putting together a rig using a Sarno V8 as the preamp and am thinking something Class D for the amp.

    I've got my eye on the Demeter Minnie 800 and GSS Sumo, and possibly a Quilter of some sort. The Sumo is the most intriguing at the moment.

    Those are all fine choices. Genzler, Mesa, and Aguilar are also always worth a look.

    Has anyone tried the Seymour Duncan Powestage 700 for the same purpose?

    Maybe it's just me, but I have used a few power/pre rigs. I'm wondering why you would want to spend $800 on a power amp to use with a bass pre?

    If you get your tone 100% from the preamp, the PowerStage 700 would be a great choice. I'd think most people would want the interaction/coloration a tube poweramp provides with those kinds of preamps, though.

    I don't get the question. I need some sort of power amp to use with the pre, so I can run some speaker cabs. Are you asking why spend $800, when there less expensive power amp options?

    That looks interesting. I can't quite figure out what it is...a power amp that has an eq?

    Much less expensive.

    Valid point. Marketing and internet forums would lead you to believe that they are all not created equally...and the more expensive ones are better?

    I have no idea...this is my first venture into class D.

    It's just power. Plenty of clean power amps that are light. No need to be bass centric.

    Yes, so you can tailor it to the room without having to go diving into your preamp or pedals to adjust for a different setting. It really works, too.

    I would get a Crown or Crest/Peavey PA amp. It's a commodity and while you enjoy your new, used, cheap PA amp you can test out other alternatives, flipping it when you pounce on something better. (Though if you're not clipping it I'm not sure there is "better.")

    I love my Genz-Benz Shuttle 6.0 (one of the first of the class D amp heads), so anything by Jeff Genzler gets my vote. Crown makes great power amps, although I have no idea about their class D offerings.

    I'm using a Genz Benz Shuttle 6.2 head, works well into a Rumble 2x10 cab. I did a session in the studio with an Arkham Octling tube preamp plugged into the power amp of the GB (bypassing the pre). I think it's better for an old school tone than the tube preamp that's built into the GB, but not necessarily worth dragging it to every bar gig.

    I've heard the Sumo power amp is nice, but have no experience with it.

    Carvin has good deals on power amps right now.

    The thing with Class D power amps is that they require a lot of limiting as they will sound really nasty if run beyond their limits. Manufacturers are all over the place with unrealistic power ratings. You need a really good module to deliver the goods and bass frequencies require the most power. A power amp that might work great for a lead guitar application may let you down if you're using it to power a 410 bass cab pumping a low B string.

    The old rule of thumb for sound reinforcement was to double the wattage rating of your power amp relative to your speaker system. The sound tech for our band prefers the old lead sled power amps but everything is pretty much going class D. He told me with class D he uses 3 times the power. I guess when you're running 6000-9000 watts with big subs and line arrays for an outdoor show the difference in headroom between various power amps becomes quite apparent. YMMV

    If it is a good quality reputable brand class D amp, you should get RMS watts as per label.
    If you are needing 3 x the power, he must be using BEHRINGER amps :bonk

    I built myself a little compact 500watt (RMS) 4 x 6.5" combo practice bass amp, using a 500 watt SMPS and 500 watts class D amp module from eBay/China, with a Fender/Alembic style tube preamp.

    For a gigging class D amp, 800 Watts into 4/2 ohms seems about the "run of the mill" type these days.
    I have been recently looking at the MESA Subway D800+ amp and lightweight cabs, wanting to replace my 2 (back breaking) Marshall VB400 all tubers and 8x10 fridges.
