Sorry Romy - I've no idea what you are on about. Did you link to the wrong post by chance?

What I am interested if you observe with your Berning amplifiers, since they have UHF pulses on filaments and in UHF modulator instead of output transformer, the “Super Texture” effect. I mention it in the post that linked:

and at:

I would also it you do not mine would like to learn want over 5kHz speakers you use and if you listen a lot of classical music.

Rectifiers
There is one thing I don´t understand:
Why is David Berning using masses of low voltage rectifiers instead of one vacuum diode rectifier?
By doing this he´s got semiconductors in the signal path.

Hi Romy,

No I really don't notice any strange treble effects - the Berning uses a simple low pass filter. The Siegfried is however noticably more susceptable to RFI and I have reason to suspect it puts out quite a bit of RF - although the bandwidth is quoted I believe as 2hz to 35khz. Subjectively though I find it to sound grainless and natural.

I crossover from the TD4003 to a TAD ET-703 at 8.5khz. As you know the ET-703 boasts extension out to 45khz but in my setup it is way down in level by then. I rarely listen to classical music I'm afraid - I suspect that may well change in years to come but, as I've only recently discovered the joys of Blue Note and Impulse I feel I have a lot of cultural catching up to do.

Berning's careing frequency?
Thanks, Merlin. Do you know what switching frequency Berning use for his pulse converter?

What is a "pulse converter" that you have a question about?
Are you talking about the carrier frequency?  What pulse converter are you talking about?  This is not a digital amp to have a pulse converter?
