Thanks all mentioning valves:
Was tempted, but had to move reasonably rapidly before wife-approval window closed and because I could get a good deal on a Primare i32/MM30 ex-demo.
Works a treat for me, although a shame I wasn't able to compare with tube.
Hesitant to put too much faith into going tube route as I do like acoustic jazz, but also electric blues, pretty heavy rock and complex orchestral material.
Not sure how tube would cope across that perhaps ridiculously wide range - within a reasonable budget...
I'd still be tempted to try, but then again don't want to end up having second thoughts about a setup I'm now very happy with...
