Fritz Carbon 7 SE MKII
AS an owner of the Carbontse mk2s I can second all the aforementioned. If truly interested in these speakers give John (Fritz) a call.  I drive mine with both a tube and a SS amplifier in rotation, each rated at 20wpc.  
Looking for recommendations for integrated with a more “organic” sound.
Another hybrid amplifier you might consider it the Pathos Classic Model One MKIII.  I once owned one and wish I never sold it. It would be in my living room system driving my Tannoy Sterlings now.   
Started with $1k speakers … what now?
Well your room is similar in size to my own. In that size room I would think your amp at 150wpc would drive the Pulsars fine. They are not as easy to drive as the Fritz however.  
Amp upgrade, speaker cables or both
I drive my tannoy Sterlings with tube amplification. Based on the Cheviots specs I believe your A23+ provides enough power. You might want to consider a tube preamp. There are several threads here on AG requesting suggestions for them.

@audioguy85 I don't believe you stated what amplification you use. You mentioned a small room, what is LXWxH?  Would make a difference when choosing between Pulsars or Carbon7s.  
Legacy Focus 20/20 Speakers AMP/Pre Amp
I now stand with @soix  regarding use of a SS amplifier I should have done more of my own research prior to answering.  Aric's preamps mate well with either tube or SS amps. Can be had with variable output gain or fixed gain based on sensitivity ... 
Legacy Focus 20/20 Speakers AMP/Pre Amp
Well 1st you must decide on the speakers. If you choose to go the the 20/20s and are interested in tube amplification a suggest you contact Aric of Aric Audio. He has a great website and is very responsive via that or a phone call.  I own one of ... 
What do you think is the best integrated amplifier under 1000
If a small footprint is sought the PS Audio Sprout is on sale for $500. Has an internal DAC and headphone amp.  Otherwise I support the recommendation for a used Rogue Audio Sphinx V3. I own both integrateds.   
Is more amp power always better...?
My thinking, a speaker having a true 89dB sensitivity to be used in a 10'x11' room can easily be by served by an amplifier providing 50wpc at 8ohms and 100wpc at 4ohms.  My advice, search for an amplifier that mates best towards the presentation ... 
Amp, Preamp, two volume pots, there can be only one!
Try backing off on the amp volume control to where you can use the preamps volume between 9 and 12 o'clock.  That may eliminate the noise while not influencing the sonics. Another approach might be to have the preamp modified to reduce the gain if... 
Accurate Sibilants: The Ultimate Audio Challenge?
SometimesI believe it is in the recording due to vocalists or instrument (piano often) being too closely miked. A bright room accentuates this. Also a particular problem with those having tinnitus.     
Rogue Audio hard to resell, has it fallen out of favor ?
The Sphinx is a great 2 channel integrated amplifier at the price point, with the power for most systems and offered by a company that supports their products. It is a hybrid having tubes in the preamp stage, some want to avoid tubes. It has featu... 
Recommendations on integrated amps
Might look into the PS Audio Sprout 100. On sale for $500. A sealed box class D amplifier with DAC. I drive a pair of B&W 685s with one.

Also I might recommend getting the book "The complete guide to high end audio" by Robert Harley.
