High end Class D amps?


Just an observation and a question. Are there 'high end' Class D amps out there that are just as good as Class A, A/B amps? I realize that's a sensitive question to some and I mean no disrespect---but whenever I see others' hifi systems on social media, all of the amps are A or A/B. There's always Pass, McIntosh, Moon, Luxman, Accuphase, etc. Where are the Class Ds? For folks out there that want more power for less efficient speakers and can't afford the uber expensive Class As, A/Bs, what is there to choose from that's close to those brands? Thanks

Dont forget the Dark Horse AGD PRODUCTION ... Class D certainly is in a higher level of performance than ever before. Many of the old issues with class D are gone. Something to realize is class D is the leading amplifier technology when compared to A and AB for HiFi.

Heres what makes AGD my top choice by a good amount when it comes to Class D. First off my personal opinion is Alberto Guerra is a better designer than Bruno Putzey. why ? well for one his products sound better to me. Next Alberto designs all the way down to the GaN device itself. Yes, that means not only does AGD not use someone elses class D module, it means AGD has thier own GaN device that is not available to anyone else. Why on earth ?  because the GaN devices on the market that are most plentiful and best from a supply standpoint and least expensive to spec into your amp design are made to be used in battery rechargers. If you are lucky you get the milspec devices used for LIDAR in the military. The AGD output device is the first and only GanFet to be designed ground up for HiFi. So when we start with that , we start at the Pinnacle of GanFet and Class D design. Forget all the others this one is different and its clear to hear. These amps are made in USA. The "Baby" of the family is a monoblock called "Audion" can be held in an outstretched hand is made from Gorgeous custom milled aluminum  with a mirror polish offered as an option. It has both RCA and XLR Inputs and WBT NextGen binding posts . Its output is 80W at 8 Ohms, but do not be deceived, it can deliver 32A of current . Thats right one reviewer powered Apogee Scintilla with this mighty mite. Why have you not heard of it ? Because it is a brand of attraction not a brand of promotion. The best brands in the world for anything are not on the fast track to push product. They steep in the market and people find out about them if they are the right buyer. Prime example Viola Labs. Most have never heard of it nor understand that it stems from the brand of HiFi considered by many to represent the most extreme example of sonic quality ever made in our industry, which was Cello, which came from the man Mark Levinson. Well AGD sounds better than Cello, Ive compared to Duet. My first buyers have been my S.E.T guys... the most hardcore of audiophiles. I have a return policy mind you and NOT ONE pair has come back. One of my guys in California has Berning 300B monos that are built to the hilt, Silver Would transformers and original Western Electric 300B tubes.. The tubes cost more then the pair of monos does. And AGD Took the cake. So I know that hearing is subjective , but if one of these amps is to be considered most innovative and most unique its the AGD for sure,  hands down,  no questions asked . Anyone want to challenge ? I am available to back my mouth up with proof in the form of shootout and recording . Do yourself a favor check out the AGD Audion , its only $7500 per pair and is 100% proprietary, sounds line no other, comes in a flght case with die cut internal foam and 2 5 foot audiophile power cables, no molded crap cord. The amp is guaranteed to overjoy you or your money back , no restock fees.  
Most toroid transformer manufacturers supply mounting hardware, and if you use it the transformer will run hotter than it should. This is because the mounting bolt is steel
A least that’s one you got right and we can agree on, this has been known btw forever since toroidal’s were first released, and especially when the bolt is in contact with the chassis earth, sorry but you did not discover it. (so no self back pats) My Hungarian EE boss (rip Steve De’Ratz) back it the 80’s told me about this, as his family tree had something to do with the first ones. And it also applies to any air core chokes, in speakers, amps, anything.
i have Nuprime MCH-K38 and MCX-4 which use the same proprietary power boards, class A and D hybrid, the former can be bridged and in that mode has more control, detail and punch. Next week I will be comparing these family offerings to the Starke Sound AD.320, which can also be bridged and is starting to get great reviews but is new. The construction quality is excellent and it too uses proprietary power boards, again not ICEPower or Hypex Ncore, and is a class AB and D hybrid. All amps should be considered for muti channel high end class d systems.
Actually, you do not want any conductive material at all for a transformer bolt.  Even a brass or non magnetic stainless steel bolt will degrade the sound compared to no bolt or plastic bolt.  You want nothing conductive above, below or in the middle of a toroid.  Again, mount the toroid off the chassis on wood and use glue and tie wraps or wooden plate on top with plastic nut and bolt.  Likewise shielding a toroid with copper, etc. will close down the sound.  If you want to shield then do it a couple of inches away from the toroid......let the toroid radiate its field.  I also do not generally like shielded wires.
Huge thread...can’t read it all.  Not sure if the AVM Evolution A5.2 was mentioned.  Incredible integrated with tube input stage for $6500 and has optional phono-stage and DAC cards.  185w of awesome power.

I hope the Rogues were mentioned, Sphinx and Pharaoh integrated amps along with the Hydra and DragoN power amps.
