Post Subject: it is rather my negative prejudges...Posted by Romy the Cat on: 3/13/2007

Yes, you are right it is rather my negative prejudges and I should not proud about it. It perfectly possible that Bend is a fine performer…. Still, it is a transformer and no mater what you do is a band-pass filter. It is still inductance at the bottom and capacitance at top. It is still not pure respective load despite that actually all that be need it to have a regular voltage divider as the function of this thing is juts to attenuate. (in fact a whole active stage of buffer also ridicules from purity perspective).

Do not get me wrong I do not question to Bent performance but I learned that over my years that as soon I see people claim an “absolute transparency for passive preamps” then I eventually recognize people with bookshelf speakers. 

Regardless, any other considerations (constant impedance, bass, HF, granularity override and many other) there is one that were I feel an good active is more interesting then any passive: dynamics.  From what I have seen the Hummel’s buffer supersede a dynamics of “straight wire” and it made me “converted”. I do not really “promote” Guy’s here but I rather promote the idea and since it is free to try I think it might be beneficial to try.

I have to admit I did see in my life a transformer that overage and increase dynamics of “straight wire”. It was not the B&S transformer and it was a different application.  In fact the B&S transformer in the very same application did very fine job but DID NOT increased dynamics. If THIS line-level B&S transformer does the “straight wire decompression tricks” then it is very good. If not then it should be looks further. Eventually you will be the one who judge…..
