Good speaker match for Sim Audio W5

Hi Arkio, I'm a Simaudio owner, but not of the big boy W5.

I'm running a pair of ProAc Tablette 50 Signatures mini monitors with a Simaudio Moon I-5 integrated, and I'm pretty darn happy. I also have a pair of Sonus Faber Concertinos, but mostly listen to the ProAcs. The scale of my sound is smaller than what you're looking to build, but I'll comment on the overall sonic character.

My I-5 can be a bit on the lean side, but I've counteracted that with Cardas Golden Cross interconnect and Analysis Plus Oval 9 speaker cable, both of which are very full sounding.

The ProAcs image wonderfully and precisely, and throw a huge soundstage. Overall, the sound is detailed, lifelike, with an enjoyable warmth.

The Sonus Fabers are warmer and fuller sounding than the Tab50s but present a vague soundstage in comparison. Also the Concertinos don't delineate the nuances of instruments and voices as well, but I still enjoy them very much. In my setup, the SFs accentuate the woodiness of acoustic instrument such as guitars.

I hope this helps you some. Good luck!

Oh yeah, the ProAcs DISAPPEAR too.

The best combination of transparency, good bass and disappearing I've ever heard was the Totem Mani 2. It is Isobarik, so it really draws a lot of current and makes stupendous bass for its small size. And it completely disappears. But it's a tough load for all but the beefiest of amps, like the W-5. I heard the Mani 2 driven by a Classe 300 series, and it was excellent. Huge soundstage, very deep. If that's beyond budget (about $4k plus stands, new), the Totem Forest is also a very nice speaker ($3k, floorstanding). I also once heard the Audio Physic Virgo driven by a Sim Celeste 4150 and that was also excellent, but leaner and punchier.
