Joseph Audio RM 25si vs Sonus Faber Grand Piano

I Own the Joseph Audio RM7 Monitors and Have Listened to the Grand Pianos at Tweeters (Probably SetUp Way Wrong)
These are 2 Completely Different Sounding Speakers... I Would Venture to Say at Opposites of the Listening Spectrum.
The Joseph Audios are So Detailed (Not Very Warm) But the Timbre is so realistic. Guess Thats why I've Heard Reviewers Say This Is a Reference Speaker, One If You Really Want to Know What the Music Is Supposed to Sound Like. Great for Tubes & Warmer Equipment Matches
The Grand Pianos when I heard them were Mellow and Fairly Lifeless Very Little resolution (Great for Bright detailed Equipment I Presume) I heard them with B&Kamp &Dennon-CD, Cables?BetterQuality?
By the Way The "Home"Pianos are the Fabers lowest end line ... even though you hear all the raves about Sonus Fabers these are speakers costing Many Times More Mula.

I heard the Joseph audio line with CJ tube gear and it sounded plenty warm. I heard the Sonus Faber Grand Piano Homes with a Plinius SA250 MkIV. IMO, these are both fine speakers, will both give you detail, etc. I would *not* say they are at *opposite* ends of the spectrum. For me, the Joseph's were a tad laid back and ultra smooth, while the Homes were a little more dynamic. But, you know what all of this proves? That
different ears hear these speakers differently -- and that's why you need to get out and listen to everything in that price range. Sonus Faber, Revel F-30, Monitor Audio GR 60, B & W...everything. Every set of speakers sound different. And, you might want to consider buying used so you get more for your money.

I just got the Grand PIanos today and have listened to it for more than 3 hours. I am using the CLasse CAP-100 to drive them.

However,I think a more powerful upfront amp would do more justice to these speakers since it's rather laidback in nature. It depends on your preference anyway and I find my 100W Classe integrated driving them reasonably well!

I own the Sonus Faber Grand Piano speakers (older model) and they need power to make them sound great. I recently upgraded my 50wpc BOW Wazoo Integrated amp to the 200wpc McIntosh MA6900 Integrated amp. The Grand Piano speakers sound much better with the increased power and the McIntosh equipment. I am enjoying them very much. cheers...
