Anything you want, of course. It is your money and your taste — this is a place with a lot of people whose taste is neutral and transparent, but anything is accepted, as long as one does not necessary equate subjective or looks with quality. This said I recommend either nothing or something...

Yup. They say “there may be new modules and who knows how they sound so we wait and they decide” spiced with a bit of wrong information.

That’s one of the many reasons I decided to have a preamp anyway. Topping Pre90. As transparent as it gets.

There is nothing wrong for that. It is when the price for the nice casework is then sold along with some mumbo jumbo as for some sonic superiority thing that there’s the problem.

If your great amp has a low input impedance, yes.

Power supplies: they are doing that. I held a Purifi power supply in my hand a few days ago. However, it is a new design, and it takes AGES for a new design to be approved by trade commissions and safety bodies in all relevant markets. So they are bringing it to the market, but the date is not...

And at those power levels THD+N is dominated by noise, not distortion, as distortion starts to pick up only after 10-20W depending on the load. They also told me “10Db better than the 1ET400A” and this fits with the latter’s 12μV (A) residual noise value. W O W.

Yep. “A” means Amplifier

I may have heard wrong, but the Topping LA90 I think achieves 2μV.

Yeah I know but it is still crazy.

NINETY-NINE opamps in parallel?!?

I am sure they will. And these amps will allow proper inclusion of the speaker in the feedback loop. Give them time: they are still a small shop at the moment, they do not have a huge R&D department.

One year of dreaming and we are finally getting closer to release!

Yeah but for what purpose?

Claus told me 4μV (IIUC) noise (A weighted), and I saw the THD+N diagram. I told him the proper adjective was “ludicrous” and, well, he admitted it sort of was… I am attaching the THD+N diagram to this post.

Sorry I do not understand what you are saying. We were talking about the “1” in the module name referring to the number of channels.

Well, you notice that I put the word elliptical in quotation marks. I meant both elliptical and 2 profile, actually, as alternatives, and mentioned both to them. In my hand-wavy report on my conversation I just used out to describe anything flatter than a disc, and a flattened disc is an...

At exactly 20Khz it is about 80° if not slightly more, but we are splitting hair here! In fact I suggested to Claus and Bruno to try also with a more “elliptic” waveguide, to increase a bit more the horizontal dispersion and reduce the vertical one - this would make it fit better in normal...

Yes, but how spectacular!
