The Khozmo Mkii Stepped attenuator

[pankon]

The cheapest upgrade you could do is to change the pots in the Croft for conductive plastic pots, such as these :

Alan, thanks for the advice. However, I am not looking for the cheapest upgrade, but for the one that will take the sound quality to the max. As mentioned, I am considering either high-end attenuators or perhaps even altogether substituting the active preamp with a passive design. Hmmm, there are real-life problems

The Khozmo is a beast. Simply, stunning.

You may have to rejig the guts to get one to fit. I did ask Glenn Croft how much it would cost to buy a 25r pre with my Khozmo fitted but never got a reply.

Oliver, the dilemma for me would be whether it would be worthwhile to completely turn to a passive preamp, such as the Khozmo dual-mono box, and not just fit the attenuators within the Croft pre.

To be honest I don't think you would notice much difference between having Khozmo attenuators or conductive plastic track pots in the Croft.

The conductive plastic tracks have a very organic sound, quite different from standard carbon track pots. This opinion is from received wisdom, but from some very well respected individuals in audio industry.

Alan,

enclosed a photo of the pots in my Micro 25RSLS. Can you or any other forum member recognize them perhaps?

There's a lot of perceived wisdom about pots etc and to be honest, there are some very notable designers that use standard pots like Alps blue and some that use plastic pots like the ones Alan pictured. There is one I know of who uses a cheap £1 version in their gear and reports are that it's excellent.

All I can say is in my own experience, I have been able to get a higher level of transparency from better pots/attenuators like that of the Khozmo compared to the Alps blue. Some will say I am imaging it but when I offered to make a cheap as chips pre v my DCB1, There wasn't any enthusiasm.

Truth is, it's a matter of taste. When I had a totally passive preamp, I never felt they offered the grip on the bass I liked. When I built he DCB1 which is effectively an active pre by way of the DCB1 Buffer board, I lost nothing of the fluidity and expanse of the passive but gained authority and slam. It suits me but may not suit you.

I searched on the Internet and found that the pots used in my Croft 25RSLS are RV24YN20S A104...

Like I said, there are a fair few who swear off high end pots/attenuators. It's a "suck it and see" situation.

And by the way, what’s the verdict? Shunt or series attenuator for a passive preamp design?

Thanks

Mine is a 50k series.

My verdict is that it's exceptional.
