thoughts on Fet Valve CF RB preamp?
« on: 23 Jun 2023, 02:29 am »
Greetings
I noticed this preamp currently on offer via eBay and I'm just curious to learn more about it.
https://www.ebay.com/itm/204372965843?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5338381866&toolid=10001&customid=60947028-1167-11ee-ba0d-376563653364
I have read the VA Audio Circle and there's not too much info about it specifically...the RB version that is.

I assume that this is just a RB version on the current Fet Valve CFR pre that is available from VA ... so the same audio circuits but no tone, filters, remote input switching, low/hi gain, etc.
Is that a correct assumption?

I'm curious how this pre would compare to the current RB10 that is available from VA and which I also own.
Is this audio circuit specifically a different sound presentation that the single 6922 per side equipped RB10? 
Is it a lower noise circuit?  Is the main benefit of a  cathode follower a very low output impedance which would be better equipped to drive the next stage in the power amp?

thanks

Yes, same audio circuits as the CFR but without all the bells and whistles.

A little bit more resolution and a little bit less “tube sound”.

Excellent value.  It is a couple years old.
