@pinwa,
The W/P 7 doesn't sound terribly similar to the Sophia II (the OP id'ed the series in a later post). I auditioned a used pair of 7's when I auditioned my Sophia II's. The W/P is more dynamic for sure (the OP would almost certainly like them better than he did the Sophias) but is, to my ears, hollow sounding in the mids and highs, and as one poster cited, a bit shouty. Works great on select music, but doesn't suit my taste on most. The Sophia II has none of these characteristics and I've been very happy with mine for a dozen years now (replaced B&W Matrix 802 S2's now in my office). Never heard any Tektons and don't really care to because unlike MC, I find them to be fugly and a half, and I'm satisfied with my system as is.
The OP wasn't happy with his Sophias so selling them makes sense to me. I just couldn't bring myself to buy speakers sound unheard as it were, they are just too idiosyncratic for that IMO. Yes the room makes a difference, but I've heard many speakers that couldn't sound good - to me - no matter what room they were in.
So good luck to the OP on his choice. If they make him happy then that's all that matters.
