There's now a ton of Class D amps. I am waiting on getting a new Aguilar Tonehammer TH500 from BassGear which looks to suit my needs best, although - as I've said in other threads - I would dearly love an integrated lightweight Sansamp/Class D head (can't understand why Tech 21 haven't gone down this route ....)
It amazes me how the various Class D heads differ. For example, Markbass have a pretty warm sound but they're (in relative terms) starting to look big and they don't have a headphone socket. The SWR Headlite is a nifty little package but tries too hard to be clever (too many controls IMHO) and the dial settings are very hard to see. The Shuttle is quite marmite according to reviews I've seen, with some criticising the overdrive tone and the (over?) bright LEDs etc etc ...
So if you were spec'ing out a Class D amp from scratch, what key features would you include .... and exclude?
