List of the best sounding amplifiers

[tommy1000]

Maybe this is a better view. The white film works as a dielectric.

 

[ontoaba]

Missing from the list are Threshold STASIS S/150 or S/300 etc.?

OK I'll picks up more careful at next list

The Soulution amplifier uses a "home made" capacitor across the output terminals. I suppose the benefit of this design is to have a non inductive capacitor and to stabilize the amplifier under different load conditions.

Looks like the dielectric has low permittivity. If it teflon or PP or PE, it should not reach 10nF, may be around 1nF.
That configuration is also not work as zobel, but work if they using current based error correction (voltage NFB need zobel that using resistor as voltage damper but current NFB may not). May be they has current sense at the OPS inputs, or it is really open loop as measured output impedance is around 0.06ohm. I am going to try with correcting input current.

Edit: I forgot that it has zobel output, There may a feedback applied as in D400, or not?

That looks like it's for insulation between the output bars, looks like delrin insulators. how would using such work as an shunting cap..? high frequencies..?

If so the thickness would make a difference ...? yes..?

 

[tommy1000]

Yes, I see what you mean. But I don't think that the thickness of the film/distance between the plates complies with the minimum creepage requirements, If there is such requirements in this position of the amp.

Class D switcher? If so, this technology has come a long way. I hope the weeping part is not due to burst ear drums!

No, Antoinel....the FM amps aren't switching amps.
However, keep watching for ever improving Class D over the next few years and see the world's high end amp makers go to switching amps as the regulations regarding efficiency get tighter and tighter.

Already we see top names such as:-

Genesis, Audio Research, Anthem and DeVialet all using Class D.

No

Me think Antoinel should have been referring to the Linn oldy.

 

[Antoinel]

Thank you acousticimagery for the info. I'll Google the names of the amp makers you wrote to learn more about them.

 

[jacco vermeulen]

You think John will weep if i show him some inside pictures of a six feet Sovereign monaural ?

 

[Antoinel]

Please do. Can this be the mother of all amps?

Love to see the pix....
I've been to a website....... Aaron Audio and a guy standing next to silver boxes with what looks like a gold ribbon driver. If these are amps, they are indeed quite large but, if they are 6 feet high then the guy is over 7 feet tall!!

 

[jacco vermeulen]

Hey, had i said other than 6 feet, it could not have been a coffin.
Merely had the impression you're heavily into numbers.

The 1811 has 6 pairs of FM17418/FM17420 output devices per channel.
They are 350W Pd each, 12 times 350 makes 4200W.
Mr Huber can turn the Papst fan in the 1811 as fast as he wants, the output stage RETs will still have to be derated.
So don't get hooked on impressive figures, a 5000CD still is an Audi 100.

(they're 4'10" high, each twice as heavy as an FM1811. case made of solid 1/2" aluminum panels that serve as heatsinks, no fans. 3-phase power transformer, output stage with about a hundred TO3 Motorolas. last time i stood next to Thomas Höhne, he was 20 years younger and could also barely get his head across)

 

[acousticimagery]

Just teasing Jacco....

Would still love to see more pix, the website is not very good.

Cheers

Contraindicated for home use without a legal document from the amp maker declaring the audiophile shall not sue for damage to hearing and to body from launched woofer cones; for self, family members and pets alike. Inclusive is damage to loudspeakers, and potential damage from irrate neighbours.

Harman Kardon Citation Sixteen 16, can add it to list of vintage amplifiers....

 

[Charles Darwin]

And my favourite QUAD amp is the 520 in BBC spec.

Basically a 606 with a pair of output transistors missing but in return it got a much larger PSU, a ground-lift switch and transformer-balanced inputs (the latter two are the 'BBC spec' part).

I agree, the list should collects vintage amps in vintage list. I also planned to add famous/infamous tags, but I am just too busy right now, with prototyping my new N3 buffer and my friend at BSN also demanding low ripple HV generators for his measurement tool.

@Tommy1000
Sorry I don't have time right now to simulate AR D400 with soulution OPS. May be another time.


N3 buffer: (taken at last night, I work with it until nightdays, happily it perform right with no problem at 1st run)

Fugly.........

Don't know but the heatsink has some problem with dust. I think it is better using helical bubble/sunflower style than radial needle.



It is my sim of soulution inspired d400, non swiching, no feedback, 0.01% THD, @ 770mA bias (enriched).
May be different with the original but it is good achievement for nonswitching mechanism.

 

[ontoaba]

I've collected some of them, and there some similarities like crown dc300 with PL700B.
I also try to buffer some opamps and old 5534 has the best sound when driving loudspeakers.
