Thiel death do we part . . .

OK, stupid title, I know...but so is my question, probably. So in spite of years of owning lots of different gear - speakers (Maggies, B&W), preamps (Bottlehead,AR), amps (C&J, Bryston) and so on, I've never quite got "the magic" I often hear about. I sort of went the path of least resistance and settled on a small setup - Theil(1.6s) & Bryston(B60) with Rega front ends (analog & digital).

The other night, however, I set it up in a near field format for the first time. After playing with speaker placement a bit, everything suddenly snapped into place, and it all sounds amazing. Magic. I found myself digging into my record collection (maybe 4000 deep) for the 1st in years and now there's not enough hours in the day to listen to it all.

One thing I've noticed is that the system is just brutal with poorly recorded media. While well produced material (Patricia Barber, Cowboy Junkies, some Rickie Lee Jones, Stan Getz and so on) can be just stunning, detailed, spacious and even deep, lots of others just aren't pleasant to listen to. Things I used to enjoy can now sound lame and muffled. I understand this may be a Thiel "take no prisoners" issue. So, just as an experiment, I swapped out the Thiels for a pair of old B&W 802s that are passing thru on the way to eBay and was surprised that while good material sounds adequate, bad material doesn't sound too bad...at least not embarrassing.

So the question is, without swapping nice speakers for not as nice on a regular basis, is there something that I can do to get the set up to be more "forgiving", at times? I listen mostly to what you might call intimate music, small groups and individual singers, often in live recordings.

Listening area is 12x18 with a low ceiling (open joists) off a corridor.

So maybe alternate cables (Zu Julian now) or a subwoofer or an equalizer? Thanks for your patience.
