I posted this elsewhere after watching Michael Nielson's video. My opinion hasn't changed after watching other videos including Jon's.
As an owner of the 100 watt Steve Morse, this baby version sounds puny by comparison. I know 2 EL84's aren't going to match the fullness of a 100 watt quad of EL34's, but this sounds like a joke. It's even more of a disappointment when you think about the Fireball 100 vs 25. Those both use big bottle tubes and in the comparison videos I've watched the 25 holds up well against the 100. The baby Morse doesn't hold up to it's big brother IMO.
The biggest draw for the 100 watt Steve Morse is channel 3's mid-matrix. Controls for both low & hi mids and independent frequency shifts on both. Then add in global tone frequency shift and there's not much that cannel alone can't cover. The 20 watter doesn't even have low and hi mid controls, just a single mid knob. If ENGL really wanted to do a simplified low watt version of the Steve Morse, they should have built it off cannel 3. Keep the low & hi mid controls and maybe cut out the frequency shift part. Then use big bottles like the Fireball 25 instead of the puny EL84's.
I guess a positive would be it seems like it stacks up fine against other EL84 low watt lunch box amps. But at $1600 list price, that's not much of a positive to stand on. Going for an ENGL at that price point I'm going to go for the less expensive Fireball 25. Or put up a few hundred more and buy the 100 watt Fireball. Both of those sound better and more full to my ears.
Overall, swing and a miss by ENGL on this one.
