Proac K6 Signature, Sonus Faber Amati Tradition,Verity Audio Amadis, Kharma DB-9

IMO it's a toss between the Proacs (as mentioned above) and the Kharma.
The Kharma look much nicer, but in my book the Proacs will rock better. They are also slightly more sensitive -- an important consideration as you only have 60W on tap.Good luck!

@garebear I understand your concern about S Tyler’s sad passing, but the speaker design is already completed and PROAC, the company, seems here to stay. More importantly, and no disrespect to Proac design, the K6 are not rocket science and you should be able to service them easily if needed -- which is unlikely!
As to the Verity Audio* model mentioned above (which i like) I don’t think they will take you to Fillmore East to listen to the Allmans as well as the Proacs:) or the Kharma for that matter.

That said, however, IIRC the Verities you like are much more efficient than the rest, so will play louder with your set-up. And they never disappoint -- but, I would add, they never enthralled (me) either!

*(The Verity model above yours (Lohengrin?) *will*, however, transport you to the Royal Albert Hall to hear Sir John Barbirollli conduct at the Proms in the 60s, AND take you to Montreux to listen to the Stones, Allmans at Fillmore, etc. They are fantastic speakers!)

@garebear IIRC: if I remember correctly
So you’re looking for a Lagavulin 25 years in a speaker... or similar!
Single malt wise, the Proac would be on the smooth side, but as they have lots of dynamics, they can bite. The Kharma are dryer and very elegant tasting, not as smooth and lush.The SF taste lush, plush, with the most elegant upper palate -- so much so they can become... unobtrusive

The Verities: it is the Lohengrin I was thinking of, I disctinctly remember three drivers in front. By the way, ribbon tweeters are nothing to worry about (the Proac has one too), at a mere 30W power (an easy load for modern drivers) you will be hitting around 105 dB which is very, very loud!

If british sound, etc, you might consider ATC 100s or even 200s. More bite than big Spendors (I had those). Subjectively speaking, Jimi Hendrix on big Proacs or big ATCs will sound like Jimi Hendrix, on (say) a Harbeth it will sound like the LSO is out of tune... (I actually like the big Harbeths)
