Speakers (and system) for a small-ish room


I bought a pair of KEF LS50 wireless for my study/home office a few months ago. First off, I am absolutely in love with the speakers. After integrating a REL sub (T9i), I moved them to the game room (20 x 25), where they are doing everything I hoped they would. So now, back to the study/home office :)

The room is about 10 x 13 ft with 12-foot ceilings. Given the way the furniture is laid out, and of course WAF considerations (she shares the office), I have very little flexibility in terms of placement. The biggest problem is that I cannot place them more than 1 foot from the wall and 4 feet apart. My desk chair is about 6 feet away from where the speakers would be eventually set up. The speakers would be flanked by two bookshelves on both sides.

My initial thought is to just get another pair of KEF LS50 wireless since I like their sound in the game room. This way I don't have to worry about getting a separate amp (integrated) and streamer. This setup has the highest WAF score :)

But then a little voice inside my head is telling me "why have the same sound everywhere?" It'll be nice to have a bit of variety. Hence this post. Given that I can get the LS50 wireless for about $2400 (including custom stands and taxes), I  want to put together a system which is around the same price. I don't intend to play anything loud in the study. Genres: jazz, vocals, some classical, some R&B and soft rock. Don't care much for metal, rap, EDM type of music.

There is an almost new pair of Harbeth P3esr for sale in my vicinity (craigslist) listed for around $1100. I'm seriously thinking of buying them. That leaves me with around $1300-1400 to spare. Does this sound feasible?

If possible I would like to experiment with tubes. But I have no idea as to how they would (a) pair with the Harbeths (always heard that they do better with SS), and (b) the cost, since tubes generally tend to be more expensive.

I am open to ideas as long as the total budget does not exceed $2500. I am willing to spend a little extra for used stands.

I cannot recommend highly enough that you grab those Harbeths....now!
More than a fair price if they're in good shape.
I similarly use Harbeth P3ESRs in my study and they are truly excellent - The best small speakers I have ever heard. Since they are a sealed system they can be placed relatively close to the wall (a foot is fine). They like a bit of power, and I would concur with their designer Alan Shaw that solid state would be best. In my case, I use my desktop computer as my only source, and an ODAC usb DAC into an Emotiva Control Freak volume control/passive pre amp into a refurbished 2x100 watt Quad 405-2 power amplfier (with some additional attenuators because the Quad has such a high input sensitivity). That is the kind of amplifier power and quality that they like. Alan Shaw recently used a 2x100 watt Yamaha AS701 to demonstrate them at the Bristol Hifi Show.
Have a look at the Harbeth Users Group, with many excellent no nonsense contributions by Alan Shaw himself. These little beauties are glorious.
