Curious what people think is the best "value" high end speaker (~5K to 15K)

Hi gene3x,
I had B&W 802s until I purchased an MC352 with a C2500 pre to match. Several people’s comments are correct about those tweeters, they were too bright and fatiguing for me, so I sold them. They were ok with my Parasound A21 Halo amp, but McIntosh pushes a much more pure and cleaner signal than the Parasound. So, after reading about JBLs Array line of speakers, I purchased the 1400s. They look like droids to me, but the cabinets are beautiful and wow, what real and unfatiguing mids and highs the compression driver horns put out! They also have a 14” woofer so bass is thundering and plentiful if so desired. There is a large port at the rear, so simply moving them closer or farther from the wall like a sub works great for adjusting the bass to your room, as JBL states in the manual. I also like the idea of having unlimited capability of replacing or repairing the drivers if necessary in the future at a decent price. Buying American is good for that. So as several people mentioned, JBL is a good suggestion and I can vouch for it being a very nice match with McIntosh power. Hope this helps!

Within the last year and half I had 3 different pairs of Tekton speakers in my dedicated audio room.  I started with the DI, progressed to DI SE and now I have a pair of the Encores.  If you're looking for the best speakers within a reasonable price, I can't imagine anything else that would fit the bill.  If you're looking for "bling" speakers to impress..., yes there are speakers out there that look nicer.  BTW, my last pair of speakers before the Tektons were the Kef Blade 2.  Great speakers, way more expensive and not sounding as good as the Tektons in my room.

B&w 800 d-2 ,having just sold my 802 d’s because they where not quite large enough,I have the focal 1038 be for a temporary fix on the way to either the 800 d2 or focal sopra 3.driven by McIntosh 601 mono blocks .skip the 100’s ,you can get the xr 200 used for around 8 k.the Mac xr200’s sound really good at low and medium volume levels and they also will go as high spl as you can take.

If buying used, I believe the best sounding and best value speaker is the Tannoy Kensington SE.  If you've never heard a Tannoy, you owe it to yourself to have the experience.  

Get a used Thiel CS3.6. Excellent bargain!!
