Replacing my Martin Logan SL3 speakers.

Had the Sequel II from 1989 to 2005 when i decided to change to a different sonic flavour and got myself a pair of Verity Parsifal and never looked back.
The ML gave me years of musical enjoyment though but the panels and power supplies needed replacement which i did not not to invest the funds for the upgrade. Sold them for $700.00 i think. ML is a very good company indeed and NOT made in China.......yet.
Best of luck in your search.

Nebin,

How are the Harbeth's with classic rock? The OP list that as being a primary genera.

The Prodigy's are a different game altogether. Try them. I don't know about this lack of support from ML. I've never had any problem or issues with their support staff. I've owned Sequel IIs and currently own a pair of Monolith IIIXs for quite some time. I've replaced the panels, power supplies and crossover using ML service and I was very happy with their service. However, if you are convinced, then the fun begins anew. Tons of decent speakers out there in your price range.

enjoy

I have not tried the Prodigy but I did try the Ascent recently. The Ascents were less efficient and the panels did not seem to integrate as well with the woofers. I much prefer the sound of my SL3s. The other problem is that ML does not seem to support the older models very well. I have had the SL3s since 1997. I think that I want to try a box speaker for awhile.

Harbeth Compact Model 7 or or the larger Harbeth models

Why are you replacing the SL3s with box speakers? Why not grab a pair of Prodigy's used for less than $5,000?

I had the SL3's and liked them very much. A step up from there would be either a pair of Vandersteen 2's or 3's. They are just as coherent as your panels but offer more resolution and body. I highly recommend you listen to them first, though. They're not as forgiving as your SL-3's. If you listen to a lot of bad recordings, its something to keep in mind. If you can find a good pair of ProAc 2.5's, you will probably like them as well. They fall somewhere in between the ML's and the Vandersteens.
