Is this upgrade worth it?

OTOH, a ML-333.5 is a true upgrade path from the #333 to the #336 although not
identical. IF THIS IS WHAT HE'S SELLING, it might be worth consideration- supposedly the ".5" upgrade was a serious attempt by levinson to add life/musicality to their austere (read- somewhat analytical-sounding) 331/332/333 series of amplifiers, using much better circuit boards and parts. in addition you'll be getting 300W/channel. again, just be sure that's the "upgrade" your friend is referring to, and not just new caps.

Having heard both, I'd have a hard time going ahead with the trade. I like Electrocompaniet, and have nothing against ML, but this sounds like a sideways move.

electros are great

Thanks for allyour replies,I'm not to sure on this upgrade either.Is it really an upgrade,the big thing for me, is it going to sound BETTER??.I think i need more power(current)and maybe thats why i'm thinking of this.It seems like the electrocompanient's don't give me the volume that i would like sometimes.They sound great, but when i turn it up they seem to get drained.Almost like a soft clipping noise.My speakers(Artemis EOS sig/large bass module) can play very loud and I would love get full potential from these speakers.

Hmmm, from yr Electros' spec'd ~220W/8ohm, 1kHz, medium damping you'd be going to ~300W/8ohm, 1kHz, low damping with the MLs. Not much of a power/energy difference, I'm afraid.

Have you ever tried a very powerful amp on these spkrs -- just to compare & contrast "ease of drive" etc. Say a big Crown pro amp -- on loan of course??
I strongly suggest you try this, just to confirm it's the energy that's lacking (or not, as it were).
