I little manual EQ will tame the pronounced mids of the Klipsch speakers which makes them sound more forward.
For movies I use Ausyssey (Denon 3310) but for music, I prefer a more laid back sound and at the same time I want it loud. Manual EQ will get me there. Even though I lose a lot of db (volume) as I am cutting down some frequencies as mush as 4 db, I can still play at high volume due to the high sensitivity. I can listen for a long time at high volume with manual EQ as the laid back sound is not fatiguing. I cant stand the forward sound for music even for a short time at high volumes. BTW I use a sub for 2ch music also and use Antomode 8033 to EQ the sub.
I had speakers like B&W 602 S2, PSB T65, Magnepan MG12 which are more laid back. But I just could not play them very loud with the AVR as a pre-pro as the pre-out voltage in the AVR's is just not high enough to get full power from my amp (Rotel RB-1080) or any amp. I have tried Emotiva USP-1 analog pre-amp. Emotiva claims a max of 9V but I doubt if it gives that high a voltage. It is an unverified claim, always with some caveat.
When I listened to the Magnepan's at the dealer store, they were driving it using a tube amp. He said the tube amp only delivers some 15W! But I was able to drive the same Magnepans to a much higher volume. I have to go back to that store and review my options for 2ch music.
Polk, Pioneer, Infinity etc are ok. They are affordable speakers but nothing impressive about their sound. They are budget speakers and that's it..
I am not a big fan of the Klipsch Icon series nor buying speakers online without hearing. I have used the Reference series RC-62, RB81, RF-82. I sold them and now I have the older Klipsch KG series (KG 3.2, 4.2, 4.5, 5.2). Yes I have 1 pair of all of them and I find them smoother than the Reference series. I only bought them for a couple of $100/pair but they are a great value for the money. I wish Klipsch made those again. They may have the slender look of the Reference series and so may not have the WAF. But I dont care. You can see the KG3.2 in my avatar.
Klipch KG3.2 (I did some refinishing and also made that stand myself)
This big guy is the Kipsch KG 5.2. No Polk or Pioneer or Infinity or Energy can beat this guy or even the smaller KG3.2. You will be amazed how much bass you get even from the smaller KG3.2. They dont make speakers like them anymore. If you want good speakers but not used, get the Reference series. I suggest RF-62 or RF-82, RC-62. Call sounddistributors or acoustic sound design
