Mid-fi tube vs high-end SS

I had some speakers designed by Murphy for Salk (SS6M) and then I bought other speakers that are more like the BMR speakers you have now (with RAAL tweeter). Your speakers, by the way, seem like excellent ones and excellent values.

In my experience, the best sound was attained in both sets of speakers with lower power tubes -- KT77’s are the best, to my ear.

Your tube amp cannot run KT77s. That raises the possibility that you might get a different tube amp.

The question becomes, what does the impedance curve on those BMR speakers look like? If it’s mostly flat, you’re good with lower power tubes, I think.

As for SS, like @wolf_garcia I have a Pass XA-25 and it’s going in my casket with me. It’s unbelievably smooth, intimate, warm, great soundstage.

Why don’t you borrow of purchase a high quality Class A SS amp and do an AB comparison with your tube amp.  You should notice that the SS will sound more accurate which might lead you to believe it’s more transparent but take notice to which design engages you more and which draws you into the the music better. See which gives you a more 3D dimensional soundstage and which design throws the soundstage out further in the room, not just behind the speakers but out towards you and even behind your listening position.

This is exactly the kind of wise, experienced, helpful comment that keeps this forum vital and worth reading. Thank you, lowtubes!
