Update.
Did some A/B testing today, between the Quilter and the DG 900 head. I plugged in various Dunwich distortion and fuzz boxes (DA120, ODB, VT, Wizard, HM2), and most of my basses, but primarily the Spector Euro 5 and Ric 4003 (jeez, my collection expanded last year).
I bought both amps, planning to keep the one I liked best. I’m pretty attached to my basses and pedals, so the amp interplay is a big factor. After today’s test, the Quilter might be getting flipped. It’s not a bad amp by any measure, but it just isn’t the best fit for my style and gear.
The Quilter clean tone is thick and lovely, but lacks a bit of top end sheen that I like in other amps. The DG has that sheen, but isn’t quite as thick and doesn’t compress as nicely (not counting the Microtubes engine, just the dry amp). However, a little EQ on the DG can get me close enough to what I like in the Quilter, but the Quilter doesn’t quite mimic the DG. I think I just like a slightly more solid-state sounding amp, in most cases.
This sound difference particularly shows itself when using distortion, fuzz, or overdrive. The DG stays pretty aggressive sounding, with a sharper attack. The Quilter sounds like there’s a layer of politeness over it. It isn’t like a when a piece of gear makes it sound like there’s a blanket over your speaker, but it might be more like a doily. There are some pedals and settings where the DG gets overly harsh, while the Quilter stays more musical. However, more often than not, I found the DG feeling like a more comfortable fit.
If I wasn’t so attached to this certain snap/attack/sheen quality, I’m sure the Quilter would be a nice workhorse amp, particularly if I was just looking to plug my bass straight into a conveniently-sized (and nicely priced) amp, and go. What I’m attached to, sonically, may very well by barely noticeable by an audience, but I mostly play for my own enjoyment. If I wasn’t able to A/B the two, I’d probably still notice the difference, but being able to play each one side by side helped me hear and feel what I thought I was hearing and feeling.
As small as the Quilter is, it isn’t enough of a size and weight savings over the DG to make that a consideration. Particularly when you take into consideration the Microtubes engine and EQ section. Both will do 2 Ohms, though the Quilter is a bit cautionary with their rating. Both have fans, and post-Master DI Out. I’ve already stayed my position on the detentes

All things considered, its not a no-contest type of choice, but it’s looking like I’ve found what works better for me.
