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

There's a Nord Acoustics One Up on audiogon for $1050 (with discrete op amp input stage, loaded with Sparkos op amps).

Otherwise, the Nord Acoustics stereo amps start at 479 Euro ($540 USD).  200 watts per channel into 8 ohms:

@vinylrecord61, I purchased 2 different class D power amplifiers and, in my opinion, NEITHER Class D amplifier was ready for prime time. I was not happy with the way they sounded, they were not musical and I eventually took the loss and sold them. As per many other Audiogon posts, it seems, everyone has an opinion about the sound quality of class D amplifiers. For me, class D amplifiers do NOT have the sound I was looking for at ANY price level. I give Class D amplifiers a F (my opinion) at any price range. I am sure that other people will disagree with me and that is okay. Everyone has a different opinion when it come to audio equipment and what sounds great.

I eventually purchased a SimAudio 700i V2 integrated amplifier and like it very much. Based on my experience, I suggest you audition some class D amplifiers and also some other class A/B amplifiers. I also own the SimAudio 340i amplifier and it is excellent. Please continue your research into class D vs. Class AB amplifiers.

Several retailers will offer you a home demo so you can listen to the amplifier in your system and then make your decision. The more important thing is maybe you NEED to find an excellent retailer (local, if possible) for advice and consult with them on what amplifier you should purchase. Based on your above comments, I strongly suggest a home demo is your best option to help you make a decision. Please remember it is your system, your environment, your budget, your other equipment and listening that decides what to purchase. It is not an easy process.

Please take your time and do not rush the process. I hope this helps.
You didn't mention a price. NAD M33 looks like a good all in one. If you just want an amp. March Audio in Australia has good Class D amps based on NCore or purifi. Nord, Apollon are others to check out.
