Thank you all for your input. I have been close to buying a pair of Guarneri's but eventually ended up buying a pair of Harbeth's Super HL-5. Unfortunately I did not have a chance to test the Guarneri's and relied on some trusted friends' mixed feelings about them -- stunningly beautiful speaker, but probably overrated in terms of its musicality and acoustic performance. Let's put it this way. I have two close friends who are professional reviewers for Italian sound magazines. Both of them recommended enthusiastically the Harbeth's I bought -- just go ahead and get them, especially if you're used to Quads ESL 57. Both of them recommended that I take a good listening to the Guarneri's before buying them...I followed their advice.
SF Guarneri Homage vs Harbeth 7ES3
I am considering either one of these two speakers. A used Guarneri does not cost much more than a new Harbeth 7ES3. I listen to a lot of Jazz, vocal, strings, country. All of my electronics is EAR (except for a Shindo preamp). Any recommendations from people who've tried both? Thanks.
