I can pipe in here and offer some insight as I've been using Yorkville/Traynor gear on and off for years. Yorkville as a company has recently re-branded all their instrument amps and cabs with the Traynor name - why I'm not sure .... brand recognition perhaps? Right now, they've got a standard line-up of cabs including 2x10, 4x10, 1x12, 1x15, 8x8, 8x10 and a 1x15/2x10. Heads are available in a 400W hybrid, 800W hybrid (both with tube pre's) and the all-tube 200W already mentioned. Then there's the combos which range from 10W up to 400W with various speaker configurations. All cabs and combos are loaded with Eminence drivers.
From personal experience I'll say this: Yorkville/Traynor gear is built like a tank and they offer an unmatched warranty. In fact, the last I heard, they'll even go beyond their standard 2 year warranty to keep customers happy. As far as the tones ...... the cabs can't be beaten. I've played everything from SWR to Trace to Eden and I keep going back to Yorkville/Traynor. They bury ANYTHING at this price-point. I can't offer much on the heads as I haven't owned one in several years but I will say that the hybrids (in particular the 800W beast) are loaded with all the bells and whistles you'd see in a much more expensive amp and sound pretty damn good to me (when demo-ing them or hearing them onstage with other bands). When I demoed the 200W all-tube head, I was impressed but not blown-away. It's good but it ain't no SVT. All in all though, I think Yorkville/Traynor is one of the great undiscovered secrets in the bass world. If I wasn't so completely hooked on Ampeg heads, I'd probably have a Traynor to match my 1x15 and 1x12 Yorkies.
Anyway - good luck. Try them all but don't get too overly hooked on the 200W all-tube head. The 800W Dynabass smokes it in terms of power, features and overall tone ...... it's surprisingly "tuby".
