The pair you may be ready to buy (or have already bought) may be my old ones if they are currently on the Gon'. I cannot comment about the Jolida other than they make great bang-for-buck components, several of which I've enjoyed very much over the years. I have not heard the 707A, but have owned a pair of Wright 3.5's. The Wrights are all about midrange magic. They have that in spades and I doubt, if you are pairing the Wrights off with one of George's preamps and some good high-efficiency horns, that you will come close to that with a Jolida integrated. What the 3.5's didn't do, which ultimately had me looking elsewhere, is bass. Granted, one is so entranced with those wonderful, palpable mids, and tremendous soundstage, that the lack of a substantial low end becomes a minor issue for some. But when I went back to my 300B SET amp, there were those magic mids along with a very realistic low end to boot. The Wright Mono-10's are a push-pull variant using a pair of 2a3 tubes and, to my ears, give you 90% of the midrange magic of the 3.5's while adding a bit more power (10 watts) and a great low end as well. I'd go that direction (and did) myself. My favorite is still the 300b SETs I own, though the Mono 10's pull a close second. I'm wanting to look closely at OTL next. Oh, and as far as the fixed cords on the 3.5's they never seemed to hold them back from doing what they do best. I suppose you may be able to tweak them to some extent with aftermarket cords if they did offer that option, but I'd say that was not to the detrement of an overall outstanding pair of amps. If you are way into the mids and wide, deep palpable image you will like the 3.5's. Sorry I can't comment on the Jolida you have in comparison.
Hope that helps.
