Berning ZH-270 Replacement
pubul57, there were many factors that contributed to David's decision to stop making the ZH-270, which was in high demand and close to 3 years out of production still is, he gets about 2 inquires a day asking for a "last special ZH-270", just one ... 
Berning ZH-270 Replacement
Ever thought of just breaking down and going with an active pre!the other option is we can talk you through a resistor/divider network design, that would drop the gain say 20-30db and sum both channels, then you can run that to the low level of th... 
Berning ZH-270 Replacement
bpinder, why don't you contact Sonus Faber and see what they say, I don't know how much input Franco has anymore but he still owns a ZH-270 and the first introduction of the Stradivarius was done using the modest ZH-270, I think it was Fremer what... 
Berning ZH-270 Replacement
With the exception of a small input DC blocking cap, the ZH-270 is DC coupled, so how is this possible with a output transformer ?? I tell you how, it's not !!We've gone down this road time and time again, it's obvious it's beyond comprehension fo... 
Duelund Capacitors??
The copper foil is well worth the extra cost, the Duelund's are exceptional components, the resistors being a no brainer best buy for sure.The caps may seem a little costly but once you compare them to others and understand the type of Machinery a... 
Replace my Berning ZH-270?
Audiofeil is absolutely correct, I use silver myself but the big BP does not recommend silver with his speakers. It takes careful selection of cables for these speakers, BP likes Cardas.A note here on this, it's not silver or copper but how the ca... 
Replace my Berning ZH-270?
Just a couple things to check, if your attenuator clicks when you turn it, make sure your attenuator is set to about 4pm when using a pre-amp, the manual says 12 or 1 but that's for the unit that does not click when you turn it.Also, carefully loo... 
I have just purchased the latest Sound Lab M1
A transformer is a transformer, a audio output transformer is something else, As I said before Ralph, there are over 2 dozen transformers in these amps and not one even comes close to being a audio output transformer, if you can't understand that,...

Oh Ralph.We're not making up stories, we're telling it like it is, our patent is available for all to see on our website.There are those that understand it and those that don't, simple. 
I have just purchased the latest Sound Lab M1
Yo Ralph.Dave did say something like that but what was meant was that the least this amp is, is an OTL, the least it is! So that people can get a little grasp, because it's not output transformer coupled, so then what is it???Having a transformer ... 
I have just purchased the latest Sound Lab M1
"If you removed the aircore transformers from your amp it wouldn't work."This is not true, it will work, but it will have to work like a regular OTL, unable to handle low impedances, as well as power requirements without a zillion smoking hot tube... 
I have just purchased the latest Sound Lab M1
Hi Ralph.So, let me get this right, it's now a transformer couple Solid state amp :) what ever happen to it being a Digital amp.Ralph, it's obvious that you don't understand the technology and that's okay man, it's a long way from the 50's type ci... 
Tube amplifiers that really drive MBL 101E's
Oh, I thought they dropped off somewhat in the lower frequencies in the 20hz and lower region but I could be wrong. Depending on the output impedance of the OTL, the flatter the speaker impedance, the better for the amp, any swings can cause some ... 
Tube amplifiers that really drive MBL 101E's
I'm not sure if he's tried those other amps, I know he's tried the big MBL amps, Krell and many other solid state amps, I would think the impedance swing on these speakers would give some regular OTL's a challenge, especially for accuracy.As well,... 
Tube amplifiers that really drive MBL 101E's
Exlibris.We are have been designing and currently building a pair of mono blocks with the intention of having great capabilities of driving MBL's, these will be 250 watts per channel, 450 watt peak, the first pair will be delivered to vetterone sh...
