What to upgrade from Totem Forrest?

agree with chayro.

Forests are a terrific speaker, I ran them with 200w of solid state very happily. I upgraded to Kharma and was surprised how much more the Kharma's had to offer, quite a bit more expensive and a good deal more speaker. S/h mine would likely be in reach, 3.2s are said to be good but don't offer the bass depth 2.3s are capable of. I had a friends Lavardin IS in my system and it did a great job, didn't offer up anything like what my amps can but drove them easily enough and I'd guess an IT might work very well indeed.

Forrests are unique speakers that can show advantages with any kind of amplification from mid-powered tube amps to high-powered SS amps. Stable 8Ohm impedance makes it drivable by any amp. Transperency, clarity tone or speed, control and punch is up to you to decide.
I've swapped them for Aerial 10T and paid almost nothing for that fantastic upgrade. Aerial 10t need minimum 250Wpc.

Many speakers can show any amp upgrade,not unusual.

I would consider upgrading everything except the analog front end. Your room is not really small and your budget can be pretty good to get a great sound.
