Class D Purifi Eigentakt / Mark Levinson 333 / Benchmark AHB2 - Listening & Conclusion
Great A/B/C subjective review of the three amps, would have I believe been my choice. 50-150hz that’s where the 802’s nasties lay, low EPDR, (low impedance with high negative phase angle), "should?" have suited the ML333 and ABH2 better as well. h... 
Thoughts on VAC preamplifiers to drive D’Agostino power amplifiers? Thoughts?
What is you source and speakers?Cheers George 
Class D amps seem poised to take over. Then what?
Well..george has an MO of trying to cherry pick items to bolster his view. You really need to get educated on this.Look at the paragraph direct above your last post, even he back down on the flagship Wilsons I mentioned that a Class-D can't d... 
Schiit CD Transport on the way soon.
More info on the Schiit transport, starts at the 27min https://www.youtube.com/watch?v=VFt8u9stoKQCheers George

It’s like Jaguar and their XK-E back in the days. Enzo Ferrari said it was the most beautiful car ever designed and they only fetch a fraction of what a used Ferrari would, due to so many being made compared to the relative scarcity of Ferraris. X... 
Worlds best amp (for 276 MHz)
Got’a be an ac mains "fuser"You going to transmit RF 😉? Maybe a Russian spy😵

Even the big high bias amps built with BJT's can't do it. Oh dear🤦‍♂️, to say that an amp doubles, is just a "saying", maybe it should read "close to doubling", but hey, I didn't make up the saying.No! amp can  perfectly double it wattage from...

These companies that claim double wattage when impedence is halved don’t give the actual 8ohm measurementUsually if they don’t, they are hiding something. Stereophile does for Class-D if you read the Lab Tests on them and that’s usually is in the ...

You keep mentioning Wilson’s as being hard to drive, where does this come from? For someone who "says" they’ve owned Wilsons, you are not very au fait or even interested in how they measure or behave, in particular the loading they present for...

Output Power: 2 x 70 W @ 8 Ohm, 2 x 130 W @ 4 Ohm It wasn’t mentionedLet see what happens into 2ohm un-bridged. (bet they can’t handle it) and those Wilson’s mentioned hit 0.9ohm!!!.Cheers George

georgehifi Next you’ll say an OTL of Ralphs can drive those Wilsons to their best properly, because they too will stay stable into them and not oscillate.🤷‍♂️ atmasphere The sales manager of Wilson had our amps for many years. FWIW our OTLs are i...

Everyone has an opinion - which is good - not everyone agrees with another persons opinion Difference is, these are measured facts, and not my opinion. And if one dismisses them then this is what they believe,  https://i.dailymail.co.uk/i/pix/scal...

They can come close if good, like the BJT ones I mentioned.,Where many Class-D go backwards! instead of trying to double, if independently measured into 2ohm from the 4ohm wattage, that shows just how current limited they are.

It amazes me how someone can say a Class-D like the AGD has no limitations into one of the hardest know speakers to drive, and for it to sound it's best.

@georgehifi - wouldn’t it depend on the original rating at 8ohms, the power supply rating that feeds the class D modules? No, although it to needs to be beefy, look at any Class-D that has been independently wattage tested into 8ohm 4ohm 2ohm rega...
