Bingo - When I bought my VTV Purifi with Sparkos buffers the parts were about the same cost and the power supplies were out of stock at Hypex. It’s a no brainer. 

I'm interested in the VTV monoblocks, but wonder if the sound improvements are essentially the same between Class D monos vs. stereo and A/B monos vs. stereo?

I have a Lyngdorf amp. I didn't think much of Class D or digital (I know D doesn't mean digital before we go there) but I went through a series of amps that I did an A-B comparison in my system, in my home, with several folks used as judges and a couple of different speakers.  I was the only one that had any idea what was what. The Lyngdorf bested all comers to my amazement. Including contenders like Liner Tube Audio and Odyssey to name a couple. The only thing I found that was am equal was a Pass amp. But not better and far more expensive especially when you also have to have an external DAC with the Pass. And this includes a digital stream and analog from a pretty high quality TT, phono pre and cartridge. It's quite amazing. No... it doesn't have tube transformer warmth (distortion) if that's what you like. It simply seems to be a wire with gain adding nothing to the system except amplification with an impossibly low noise floor. It will certainly pass though anything you do upstream of it. My wife, without any knowledge of the change, immediately noticed a difference in sound when I swapped one USB cable upstream of it. What does that tell you?

   Yeah, I have a few (and have sold quite a few) very nice sounding amps. I've put them into my system at times and I do find things that I like about each of them, but after listening to them for a while I keep putting the Cherry Megaschino class D amplifier back in and leaving it there for a long time. I have a sensitivity to the harsh upper midrange which gives me listening fatigue, but I do not get that fatigue from the Cherry amp. I am also a stickler for details and I have irritated my wife by playing tracks over and over again while I listen for subtle differences and details. I no longer irritate her with the monotony of repeatedly playing the same song, but now, for the first time in the forty plus years we've been married she turns on the system and plays the music she likes. She says it has never sounded as good as it does now. I think my  amplifier quest has ended. Now I'll direct my efforts on improving other parts of my system.

I agree totally.
I've owned way more than 100 good amps over a half century, including about 20 class D contenders of various topologies as they've advanced the technology.
I now own 2 sets of Maraschino Kings and a TDSS modded Nuprime IDA-8 for my 3 mature systems. The little Nuprime DAC/integrated is very nice within its power limits, but the Maraschino Kings are giant killers, and very reliable to boot. They've taken me off the amp market, perhaps for good.
I'll add that I'm driving the Maraschinos with TDSS modded Nuprime DAC10H DAC/preamps and the music just flows, as it does live. Lovely. The TDSS mods are inexpensive and well worth it for the Nuprimes, imo.

Jonbee,
Do you use the King in line monos or the STM?

Lygdorf is a co-founder if Purifi. This group is like a who’s who of interesting audio of the last 20 years.

Hypex NCore has the best value today (MP series is killer), and Purifi for the highest performance.
Orchard is also interesting.

ICEpower is catching up with ICEedge (in 1200AS only so far), but their other amp models (as well as Pascal, Crown, and others) are still behind.

Several manufacturers to choose from: Nord, Apollon, March, Audiophonics, VTV, boXem, Vera, etc.

This year I bought my 4th class D amp (had and sold 2 ICEpower based amps, now on my 2nd NCore).

Hi Guys,

In the early 2000's I regularly listened to a pair of Bel Canto tripath amplifiers and I totally loved the sound.  They then changed to I think ice power modules and whilst very transparent the amplifier sounded boring. On a whim I bought a ps audio hca2 due to the great reviews and I remember at the time reading one bad review from 10 audio.  Well guess what he was right the amplifier sound really bad.

Anyway, as I am stubborn I found a guy in the USA who modded the living daylights out of the amplifier. i.e you name black gate caps, nichicon gold caps, v caps and special silver harness wiring.  On return it sounded great but gee the cost :(.  I still the amplifier this day after 15 years. It sounds very good.

I had a peachtree audio nova 150 which is a digital amplifier and I thought it was a terrific buy.

Good luck with your decision.

Cheers Rod

The Orchard Audio BOSC, now called Starkrimson monoblocks sound excellent on my planar mids and tweeter in my system. 

Leo was shipping them for demo's, so that might still be possible to hear it in your system.  The really short speaker cables do sound much better if you can.

Good luck with the search.

I've heard many digital amps, and the latest Purifi stuff is lots better than the prior generations.  But for my tastes, nothing is as good as the Digital Audio Company (DAC) amps.

Very ironic I saw this post. I am literally talking to Tommy right now about GAME ENDING amps for my system and new custom ZU Audio Dirty Weekends. I am going with a pair of MEGAschino MK2 monoblocks.

I am right there with you Tyson. I have heard a lot of CLASS D amps and they are very good. No reason not to go with CLASS D. But Tommy's amps over at (DAC) are by far superior to anything I've ever owned or heard in my systems. Not just CLASS D, but all Classes whether that be CLASS A, A/B, tube, SS. They're a great amp regardless. Never realized the full potential of my current ZU's until I paired them with (DAC) amps. I am on my 4th pair of amps. I just keep climbing that ladder!  :D

Great to hear!!  You're about to purchase my dream amps. They're well beyond my budget right now. Enjoy!
