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.

You might want to consider some Vandersteen VLR.  Simply amazing sound and can be positioned close to the wall behind them.  In fact, they're designed to do just that.  Incredible for the price and incredible regardless of price.  Best of luck...
How about a something like the iFi Retro system that Music Direct sells for 1995.00?  That system would meet your requirements and give you an opportunity to explore tube sound.  The el84 output tubes are cheap and don’t make much heat so should have no problem playing all day.
I had the same issue. Give me a reason not to buy another KEF for the office since it would be the same sound. I would have 3 KEF systems. If you are interested in my KEF less journey take a look at some of my posts regarding a new office system.
Thanks for the suggestions. I had not considered Vandersteen before, but the VLR surely looks promising. For some reason, I always thought that Vandersteens were better as floorstanders. The only problem is that I don't see any used ones for sale. And I don't want to buy new. Which also rules out the iFi Retro system.

@yogiboy  Would you mind telling me which tube amp (or integrated) you're using with your harbeths?

@yyzsantabarbara  Sorry for being dense, but I'm not able to comprehend your answer. Are you making a case in favor of KEF or against them? Lol, sorry for being dense. 

As of today, the p3esr's are available locally, and the seller is willing to part with them for $1150. He is claiming that they are only about a year old and pretty much flawless. The only thing is that once I buy them, I have to look for stands and an integrated amp, etc.

Part of me is saying that I should just get another KEF LS50 wireless and be done with it. No need to match it with another amp or streamer. I already know, and like, the sound characteristics.

Tough decision. But I guess I need to move fast before those Harbeths are gone. The good thing is that if I get them at this price, I don't think I'll have any problems moving them without incurring a loss if I'm not satisfied.
@schubert  I did some research on Totems and Silverline. 
Based on reviews, it seems that the Totems might be a bit forward sounding compared to the Harbeth. That's not necessarily a bad thing, but I don't know how this would play out if I'm only seated about 6 feet from them.

I'll look into Silverlines, maybe there's a used pair available for sale somewhere.
