Speaker Suggestions for Next Move

@mijostyn -- Sir, I like the way you think. To the vast, VAST, majority of music lovers, the Klipsch Cornwall IV’s are an endgame, end of the search, speaker. I know the deal with Klipsch -- they are either revered or despised by members of this Forum. I love them.  I have Forte II's, Heresy II's, and (soon) La Scalla's.  But be honest. The community on this Forum are a mere fraction of 1% of the listening public and consumers of audio gear. I’m a "To Each His Own" and "Live And Let Live" kind of guy, always have been. Spend your money how you and your conscious want to spend it. But I still shake my head at times at the threads on this site and the debates they create: "No don’t buy XYZ integrated amp (at $60,000), buy LMNOP separates (at $80,000)" or "I’m looking for new speakers. My Magico S7’s just don’t have the soundstage I’m looking for."

Your suggestion is the most reasonable idea I’ve seen. Again, you’ve got Cornwall IV’s and you’ve done some awesome modifications on an already awesome speaker. Maybe, just maybe, some modifications (Room Correction, EQ Processors) to the signal and you will find the Nirvana (not the band) you are looking for. Sounds a lot more sane and less expensive than chasing an entire new speaker system that you may or may not like. Try your suggestion first, and if the desired sound can’t be achieved by the signal modifications, then start looking at new speakers. Just adding my nickel to your 2 cents worth.

No mention of the recent release of one of the PS Audio Aspen speakers. Worth considering. FR10 or FR20 

You mentioned Vandersteen in your list and at the price point you're looking at with your room size, I'd recommend a pair of Quattro Wood CTs. They might press your budget a little bit but if what your looking for is imaging and depth they'll have it in spades. They are not too fiddly with set up, if you buy them from a reputable dealer then they'll usually come set them up. They have built in room tunable subs as well so bass management is not udally an issue. Also, since the bass is not in the picture for your amps, despite a sensitivity I the high 80s, they're really quite an easy load. They're not trendy or the newest greatest thing but what they are is excelle t loudspeakers. I've had mine for 8 years now and have no interest in upgrading unless I can go up their line to the Kento or maybe a used 5. I've changed every other component and with each upgrade the speakers just get better. 

I do like my aspen fr 30 all aspens are hard to find used but I did find a pair.they sound great.i run them with bhk 600 found it used as well.they do have a trade in program.check thier web site. I have some klipsch ps takes alot more watts.enjoy the hint.you can visit ps audio and listen 

@allenf1963 The thing is, I have rescued several systems this way, just by inserting one of these digital preamps. People do not realize how much their room and channel deviation interferes with a proper image and impulse response. I have never heard a system that could not be improved and in terms of satisfaction, it is off the charts. it is an easy recommendation because it works 100% of the time.
