I am building a F5V3 and would like to know whether a passive volume control shunt series type will work well with it. Source is a DVD player.
Thank you.
Thank you.
Yes I will have it right next to the amp input and in my usual loud listening position I plan on keeping the total of series and shunt resistance around 10k. Just wondering whether a buffer will sound better than a simple passive with an F5V3 based on the experience of those who have already tried it? Thanks.
no problem regarding F5 an pot ;
will that be better with buffer in front of pot is more source issue - how's your DVD happy to drive 10K

I've used an LDR type attenuator followed by a Salas DCB1 with the V2 turbo and it did sound good.
I'm currently enjoying an Aleph J though.

Presently I use the passive with 6.8K series and around 1k to 3k shunts at my commonly used positions to drive a Hafler 9505 which has 29db gain. I find myself listening between -17db attenuation to -11db attenuation. The DVP is a Sony DVPS9000es and the resultant sound is excellent. I am planning on building the F5V3 with 26db gain bumping up from NP's 22db gain in the schematic.
I recall reading NP saying something about the capacitances of the output devices having an effect and thats why he cautions against using passives with the VFET design. I will be using Toshiba 2SK1530/201 in the F5V3. The Hafler 9505 has Hitachi 2SK1058/SJ162. Dont know whether output device capacitance is an issue here? That's why the original question whether a passive will work.
Thanks.
How would you say it sounded with just the LDR passive vs. LDR plus the Salas DCB1? What was the input impedance of the LDR? Thanks
there is F5's input stage to take care of it ;
attenuator value and position is completely different issue
