Guys and gals:
I have finally decided to upgrade (but keep) my beloved old Heybrook HB1s (bought at the end of 1984 from the old Sound Org shop at London Bridge).
With £1,500 to spend (including stands) a visit to my dealer earlier yielded the suggestion of ATC SCM11s. Nice and compact, decent WAF scores and rave reviews. I've heard them in another context and was pretty wowed by them.
I've got a listening room demo booked for next week, with the option of taking them home for a week or two before buying. I don't really want to spend weeks faffing about comparing speakers and I don't have a penny more than £1,500 to spend. Once I hear something that has the qualities of the HB1s - fun, speed, leanness etc - but better, that's what I'll buy. (And if the ATCs don't offer a massive improvement on what I've already got, I might replace my Lingo 2 with a Lingo 4 instead...)
However if anyone has any suggestions (my dealer also stocks B&W - I have to say I'm not a huge fan of the B&Ws I've heard, I think they're boring - Rega, PMC, Neat, Dynaudio, Focal - not a fan - and Linn speakers) that I might audition within my budget, they'll be gratefully received.
