Wilson Sophia III vs Sasha

Sounds_real_audio
Yes, the Densen is a Class A amp. The B-350 delivers 125W at 8 ohm, and 250W in 4 ohm. No local or global feedback. I would be required to spend significantly more money to improve the sound.

Peterayer: >>I learned that the room and isolation are just as important or even more so.<<

I agree 100%. Acoustic treatment, as called for by system setup within the room, and a decent rack for vibration isolation are key. I believe swapping gear is a waste of time (and possibly money) until you get these right.

If you can create a simple line drawing of your room with equipment and furniture placement (I used Visio) many of the acoustic treatment vendors will give you a complimentary consult on products and placement. Use a mirror or the reflective mylar strip from ASC Tube Traps (aka Optical Alignment Kit) to find reflection points. It is actually quite simple. This is fundamental 'aural infrastructure' stuff. PS: Don't forget the ceiling.

I went with RealTraps and SRA and they've paid huge dividends. Sorry don't mean to sidetrack yr thread. Fwiw, my pick was Sashas.

IMO It's best for you to listen to sasha first, then decide if it's worth the $15K upgrade, you can tune the room later if you have found your setup.

When auditioning speakers for my new system, I found that the Sashas paired with an Audio Research 200 wpc integrated amp sounded great - up until about 80 on the volume control, when the ARC just didn't have the power reserves to handle recordings with substantial bass. So I think your concern about adequate power is legitimate if you plan to play them loud, and that taking your gear to the dealer to see how well it drives the Sashas is an excellent idea.

But although I went with Revel Salon 2s due to my particular room circumstances that required a more forgiving speaker, I will say that the Sashas are outstanding speakers and I think noticeably better than Sophias, especially in a larger room.

Ricred,
Re my initial suggestion to getting speaker first is none other than that from previous experiences, different speakers usually do require different treatments--optimally.

If modular units--still ok, you might just need to add, subtract, or simply move them around. However, if fixed/built into room--then not so easy, more headache should you later decide to switch speakers. Hence for me, whenever possible, always better to get a fixed on designated speaker first, then specifically treat room around it. As in your case : what Sasha requires might differ from that of Sophia's.

But at the end, either ways, whether it be room/speaker first--some corner bass traps, front wall, and sides' first reflection absorb/diffusers are basic essentials which will definitely reap benefits in almost any room.

Also, if you go modular--your ears, with some dealer's help (basic measurements) can do, no need Rives etc. Only if you plan on built-in ones incorporating some sort of room re-design, then those pros will come in handy, ime.
