I wouldn't say it's hot per say... But if you compare them to a very nice class a or class ab amp... It just doesn't come close in fleshing out the same experience- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Tom, My current setup vs previous...but there are other D amps that are highly praised for their smooth sound.
Trey, I have to disagree. It is all about synergy and you can find the right match with Class D. I'll admit a good single ended amp usually sounds better to my ears, but I live in the deep South and I don't like to add heat to my room. It's a trade-off I'll make...those usually don't make enough power for my needs anyway unless you get into a 50000 BTU Krell KSA or similar. -
What I found in my little experiment is my tiny amps were light in the bass but I couldn't find a problem with their top end. I really was amazed they had the control over all the drivers that they did. I let them play all afternoon and for one side of Joe Bonamassa's live at Royal Albert Hall I played them as loud as they'd go. They imaged 3' to the sides of the boxes. forward of the speakers at times, weren't fatiguing, showed no sign of stress or any other issues and didn't get hot. No the kick drums didn't have the impact they normally do but I didn't expect they would. In their defense these puny amps cost me less than $200, drive a much easier load daily and sound very good in the process. Class d 3255 chip amps have come a long way quickly.
With that being said the brutish Mac's with their 200 amps of current are still secure in their position and I won't be revisiting this comparison. This was nothing more than an experiment out of boredom. In all honesty I was hoping the little amps would fail the experiment but alas they did not. -
Class d is great for bass
Everything else? Meh... Especially high frequencies... Yowza
So true, especially when you compare Class D (Purifi Eigentakt) back to back with a good 300B amp! -

Nice, are those Fosi's PFFB-3255 amps?Don't take experimental gene therapies from known eugenicists. -

Yes they are the PFFB v3's. They also have upgraded op amps (not Sparkos) and share the same 48 volt ps with the Fosi dc blocker.
I was really hoping they'd be as far apart soundwise from the Mac's as their difference in size and basic specs would suggest. -
That is a saying something. And I was worried if they would push a set of 3.1TL's.
Also, do you have them hooked up with a Dreadnaught IC?Don't take experimental gene therapies from known eugenicists. -

Yes the dreadnaught is in place. The Fosi's normal load is 2 pair of IMF supercompacts wired in parallel which they are a great match for. I figured for sure they'd puke out driving the 1.2tls and maybe even go into protection mode at max volume. I was wrong; not a hint of distress or bad sound all afternoon. But now that I know that there's no need to revisit that experiment. The Mac's are safe in their spot especially since I can no longer lift them alone -
One more important note is those monoblocks can take their own separate 48V,5A power supplies. Should give more bottom end oomph. Still impressive results none the less.Don't take experimental gene therapies from known eugenicists.

Added this Emotiva XPR-5 to my home theater.

I will never use gear with those letters. I would be worried about something blowing up or a Boxter driven by ladybois in skinny jeans pulling in my driveway...

Two weeks ago I picked up a pair of Red Dragon Audio M500’s. I still have the Aric Audio Motherlode II,and they are driving my Nola Boxer 2’s. This is my first taste of class D. They are older ice technology,but I’m really enjoying them. Yesterday I ordered a pair of SVS 3000 Micros. I’ll see if they will stay in the main listening room,or go into the Pit,the secondary system.

If at all possible, you may want to entertain losing the loop(s), as you have created an antenna that attracts both EMI and RFI.
I.E. - Unwanted noise.
Other than that, looks like you are having some fun! Enjoy.

Thanks for the advice Tom. At some point, I need to pick up some shorter PC’s, unless I move the amps farther away.See my profile for list of gear.

I'll say, especially when you have that nice of a cartridge! Enjoy! -
We recently got my favorite chair back from being refurbished. Fresh upholstery and had the internal frame rebuilt. Glad to have it back in the primary listening position.

Yesterday, replaced the two Input Attenuator's on the Clair Bros Phase Linear 700's.
Today, going in to the Balance Pot Control to get some static out. Some Deox & Lube.
If that doesn't cure the static noise and dropping out it's time for a replacement. -
Trying out a Memory Player (on loan from a friend). So far, pretty impressive with simply plugging it in and hitting play.

The Laufer Teknic one or something else? -
I could use a memory player, can you set the date and time of the memory to play?

I moved my mono amps off of a common stand,and stretched out the power cables to unloop them. I like the way it’s more open between the speakers. That is until I put the J2 back in the system.

Sold my ps audio perfect wave with bridge 2
And considering a hifi rose rs151or a eversolo dmp a10 . -
Have the week off, decided to pull out my Van Halen inspired Monitor 7’s and give them a workout for a few days.😎
Sent those pics to Alex!See my profile for list of gear. -
I ended up purchasing the Memory Player. It was a deal that was too good to pass up. Now I have 4 sources. Physical CD and LP sources, and with this, streaming through the Lumin as well as playing the collection (and currently loaded music) through the Memory Player.
The memory has only just been started, yet I could load my entire collection onto it, and it still wouldn't make a dent. There is already enough music on it to not even listen to everything on it well into the end of the new year if I listened constantly.
I still have some things to set up, but the next test will be to rip a CD and see if the claims for physical music are bested by a copy on a different player. That has never been the case before, so we shall see.
I have heard things on a copy that weren't as prevalent or noticeable on the original CD, but at the same time, I have always been able to detect the difference between the two and there was no clear winner as to which sounded better/worse. There were simply differences between the two, and that was it.
This should be interesting and quite a bit of fun!

The one thing that sucks? Managing the cables and doing the human pretzel in order to do so.....or even hook things up or disconnect.
I need more real estate for the rig, period.

There were a few cds back in the day that actually had Easter eggs when you ripped it and it wasn't audible on the disc originally- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
