New Bel Canto Gear at RMAF

Hello Tvad,

"H20 Class D amplifiers use very robust torroid/capacitor power supplies"

..and its probably one of the reason why they have a good reputation.

To know exactly what they are capable of (in power department) I would like to know
their peak power (Spectron 7000 watts)
their peak voltage (Spectron +/- 240 volts)
duration (Spectron - 0.4 second)
Distortions - AT FULL OUTPUT and at 20 kHz, I don;t remember that of Spectron but you can find it on their web site.
Most other manufacturers show their distortion levels at 10 watts and 1 kHz - which is not highly relevant to real music

Good capability do not translate automatucally into good performance, obviously. However, poor or mediocre capability CANNOT be transpated into good performance.

Again, the "power" of Krell is not in its rms but in its massive power supplies

Note, most class D manufacturers include in their specs words "soft clipping" and why? ...because they clip but if you are semi-deaf it will not hurt your hearing!

I have nothing against H2O - in its price range its one of the best (as I understand).

All The Best

Rafael, while there is moderate correlation -- at least in principle -- between price and performance, I prefer not to venture too many prognostications. By the way, JRDG 312 uses twin swwitching power supplies, rather than linear/toroidals. See the sidebar on 312 on issue 188 of TAS--I believe around page 80.
My general philosophy on the subject of power supplies is best summarized by the words of Igor Stravinsky in the Poetics Of Music: "By its fruit we judge the tree. Judge the tree by its fruit then, and do not meddle with the roots. Function justifies an organ, no matter how strange the organ may appear in the eyes of those who are not accustomed to see it functioning."
For the time being, I can only state that I really liked what little I heard of the Bel Canto Mk.2 series, and that they are currently somewhere towards the top of my preferencial non-integrated amplifying heap, together with the class D JRDG 312 stereo, the class A/B Theta Citadel monos, and the class D Spectron. .

Hello Tvad,

"I was just correcting your statement with a pertinent example" - unless you state that H2O amplifier is in the same class as Jeff Rowland 312 you dod not correct or in-correct anything but thank you for your kind thoughts.

Guido,
I know that Jeff Rowland 312 and Continium (I believe) uses swithing power supplies and also power correction which help regulate this power supply (but not to 100%!!) and so what?

With this exception (and I believe I stated it in my post above and if not I am bitterly sorry) - every class D amplifier which uses switching power supplies provides inferior performance IN MY OPINION.

We talked, however, about Bel Canto Mk2 - I don't know if they use witching power supplies (I suspect so) and if so is it with power correction or not.

Where I strongly disagree with you - its only in one thing. I cannot make final judgment on the piece of equipment based only on its sonics during audio show with imperfect acoustic, thousands of people etc.
If you can - fine, just please don;t force me too.
its possible that I will investigate seriously Bel Canto and I will agree with you - and I will state so publicly and until that time let me stay with the opinion that Bel Canto was very good and worth investigating but... no more.
You recommend this amp for people to buy to spent big money and I can't (yet..).

I hope it clarifies things. Sometimes, I feel on this forum as in the court of low - you say a word incorrectly or correctly and word has more then one meaning - you are "attacked". Its OK, I can live with it, rather happily (I have my Spectrons!!!!!)

All The Best
Rafael
P.S. I am out of this "discussion"

Guido my friend, what's the issue # of that TAS?
