Thanks for all these suggestions
Those HO Super 3's look terrific.
To be clear, I'm currently using my SET 120 and RB10 with the aforementioned Omega's (Super 7's) and my Magnepans.

In both cases, the results are super!
That said, because of the Omegas high sensitivity, I do get a little bit of noise floor and currently one of the tubes in my RB10 is a little whooshy.
So I'm thinking something in mid 80 db's in terms of speaker sense might make sense.
I'm seriously considering getting one of the new SET 400 or 500 or whatever is about to be released to use with my LRS's in a different space.
Anyone one else using an ls5/3a variant?
Or...for something completely different , has anyone tried the new LSA Signature 50 from Underwood with their SET 120?
