Switch from AB to D

I have a Onkyo TX NR 3007 that eats up electricity because of 4 amps inside. I would like to switch to the Vidar class D from Schitt's. I really like what I've read about it and the reviews. I am handicapped and can't get out to listen to any class D units in my area so I'm going to depend on some people here give me a good idea where I'd be going from class A B to class D what's my sound. I will be using the Vidar with a Audio Experience Symphony preamp with three matching Telefunken tubes that have been in there since I bought it and it's serviced me well along with an Audio Experience Concerto Plus phono preamp. I have an older Soto Sapphire turntable with a clear audio virtuoso cartridge wooden body that has been rebuilt by the soundsmith what a great sound. Oh by the way I have an Oppo 103 Player for my digital along with PSB image five speakers which I got for a great deal of many years ago and they still sound good with my system.
So the bottom line here ladies and gentlemen what am I going to experience putting a Class D amp with a hundred watts per Channel in place of my Onkyo with 140 watts per Channel at class A B power?
Thank you much

Hey Ron,

I replaced an Edge M6 A/B amp with Nuforce Reference 9 SE V3 mono amps that are 175 watts/ channel class D.  I loved the sound--much more detail, more dynamic, and just better all round.  Later on,  I had TDSS do their level 3 upgrades to the power supply along with key other areas.  Suddenly, I had very near SOTA amps in SQ and they would be even more reliable--TDSS does not change any of the circuitry, but does change key elements in the amps.  These amps new were $5200 for the pair without the TDSS mods. 

I have VMPS RM40 BCSE w/ MLS cabinets and most all the upgrades in them.  These have 40" of ribbon drivers, along with 2 10" woofers and a 10" passive radiator per speaker and have just got better with each upgrade I've done.  The amps are very small, don't get hot, and drive the power hungry 40's with great drive.  There is absolutely NO problem anywhere in the sound with these amps in my system.   I paid $1400 for the amps used originally and the TDSS upgrades are $2400, but even if you started with just the Ref 9's without the TDSS upgrades, the SQ is still very good.  Later, you could add the upgrades and be in hog heaven.
