Upgrading from Thiel 2.7 to Sonus Faber or Focal???

For my smallish room, I demoed the Magico A3 and was also considering the Kanata 2 because of the ease of placement (never demoed it). However, I went with a used Thiel CS3.7 (that I completely rebuilt), I think it is still a great choice and definitely not a step down from any of the speakers I demoed. It is rather difficult to drive though. Maybe your 2.7 needs more power. I have no clue about your amp or the specs on the 2.7. I am just going by my experience with the 3.7.

I demoed the following:

Magico A3
Vivid Kaya 90
TAD ME1
Paradigm Persona 3F/5F
Vandersteen Treo CT
Yamaha NS5000*

*The Yamaha is the only one that I liked as much as the 3.7. I need to navigate some house politics before I can buy the Yamaha for another room. It has more bass than the 3.7 and is a little warmer (maybe). You can get home demos of the Yamaha from the online seller.

Definitely not Focals if you want warm, though they are warmER than Thiels.

I think the 2.7 has the same COAX as the 3.7. If so, the Focal is definitely not as warm as the Thiel.

Might be worth getting REW, a UMIK-1 calibrated USB microphone, and doing a frequency sweep of your room.

This is a great suggestion. I did the same to get my large speakers to fit into my small room (plus some other things with the data).

Magico A3 needs good SS power. I tried with 100 watt AHB2 and it was pretty bad. Today, I am actually using 2 AHB2's for a speaker even more demanding than the A3. The A3 did sound great with the Mark Levinson 585 integrated and the $20K each ML separates.

The A5 is supposed to be a much bigger step up from the A3. 

My favorite Magico is the S3 MKII.
