Legacy Audio Focus SE and rivals

I’m looking at either the Signature SE or Focus SE. I have a decent size room: 18’ x 24’ x 9’ and I sit about 10 feet back (dining room is behind me and opens to the kitchen as well), the tweeters will be about 8 feet between them. Back of speaker will 18 inches from the wall and side walls are about 3’ for the right and 6’ for the left. Is the 18” to the back wall suggesting the Signature SE is the better option?

I’m leaning to the SE vs XD because I’m concerned that the internal amp in the speaker is another thing that could go wrong and shipping off a speaker for that repair isn’t appealing.

Regarding the amp, obviously Legacy’s Power Block 2 would be a good option. Also looking at a Buckeye Purifi amp or a wild card I’m reading up on is the Tone Winner AD-1 PA+. Any thoughts ?

I have the Focus SE paired with Ayon Triton Evo and love them. Do recommend getting  at least 18 inches from the wall. 

I recently purchased a pair of Focus SE.  I auditioned the Signature and SE and although the Signature is a terrific speaker, I thought the additional mid range driver in the Focus SE brought a little more to the table.  I was concerned with speaker height but after getting them home and letting them settle in, the height is not an issue, they have a small footprint and they integrate well into my living room.  I'm powering my Focus SE with a McIntosh C2600 tube preamp and a McIntosh MC 462 solid state amp.  I would agree with the comments previously that these speakers will sound great with almost any amp.  I have 40 wpc tube monoblocks and also 90 wpc Class A tube monoblocks which I will also try.  These are terrific speakers and I find them to be relatively neutral, nice detail, great bass and non-fatiguing.  I listen to a variety of music and they play it all well.  My room is 20'-6" L x 13'-6" W with a 8' - 11' vaulted ceiling.  I sit about 10' from the face of the speakers.  My speakers are 8'-2" on center along the long wall and the back of the speaker is 18" from the wall behind them.  They are slightly toed in.  They do take a little while to break in and I prefer them bi-wired.  If you have a much smaller room, you might consider the Signatures due to potential bass overload from the Focus SE dual woofers

I've always been curious about these, for those that have experience I've got Focal Kanta 3s and have heard (and like) most of the brand. How does Legacy contrast?

No comparison to Focal. I sold my Electra 1038s for these (signature SE) and couldn't be happier. Could never (after 6 years ) get the Focals to loose the clinical, fatiguing presentation.. Legacy makes music.
