As long as they are the “best” to you is all that matters. But I have heard many systems and I can tell yours is up there. The frequency response in your thread is right on target with the slight tilt of the Harman House curve. I know what the GRS planar can do and I know Tang Band paper cone full ranges works well as a mid. I know you have got a great amp! 😂
You have a system to be proud of and can enjoy now. So spend some time relaxing and listening to music for a long time. Until the itch to build the XSD creeps in.
Speaking of Pearl 3, I am listening to Jhofland’s version and it sounds fantastic. I have a much more basic TT though but nice cartridge.
Cheers,
X

Many thanks for the kind words, X!
It's great to read this from someone who is light years ahead of me in speaker design!
Yes, now I enjoy the music, I listen to it since many hours now and it's just beautiful.
However... I have so much itch when it comes to building... HyperSET, Pearl 3, some linear PSUs...
And of course I have to finish the xo of The Open Baffle (currently it's a lump of components with point-to-point soldering) and the birch ply baffles will also arrive soon (instead of the MDF ones)... so, very much to do
But that's fun
Many thanks again!

I have the A40 Class A amp coming out soon. It sounds amazing - full time SE push pull Class A Alpha Nirvana topology with 250 damping factor for bass so unbelievable woofer cone control.
I will also be developing a hybrid tube buffer Class D amp with 350wpc for a client as a commercial amp. Still early stages.

Thanks for the reply. My concern with Class A amps is the behavior at "weird" speakers on terms of strange impedance curve. It's mostly not in the bass range, rather in the mids, and it can cause a shouty midrange without control.
Your Class D plan is great - but being a commercial thingie, no chance

You could just build the Alpha Nirvana. Same amp. Add the SFPP and SSR speaker protects. Add the SLB power supply if you want to go all out.

Here is an example of the Alpha Nirvana in an exquisite build by Sledwards:

His build is also very impressive but I can’t find the thread off the top of my head.
The amp itself is quite simple all through hole parts.

Wow. Thanks X, I have to think about it, but it looks really great.
What's the difference between A40 and Alpha Nirvana, if any (if it's not a secret, which of course I would understand)?
The boards are in the shop; there is an SFPP with lot of SMD (no go for me), and an SFP with soldered SMDs - would it be okay too?
I fear a new project is born... 🙈

Hi X - or anyone familiar with both
How do the original xrk TPA3255 Reference amps sound, compared with the newer version with PFFB?
more so in terms of tonality. I highlight that, as it’s probably the last good attribute you might not expect from class D
Don't forget that the system response also improves a little.
I am mostly talking about the peak you can get from the LC filter at higher impedances.
I have seen cases where this has quite an effect already around 10-20kHz.
