Hi all. I thought I would try a passive pre as my TT does not get any use.
Totally puzzled on how I determine the log value needed
Any ideas??

SS amps generally have lower input impedances, perhaps 22K or 10K on some.
Valve amps generally have higher input impedances, perhaps 100K or even going as high as 1M.
I usually opt for something in the middle that will work with either, so 50K for me.

Thanks Alan, the Sirius is 10k so it should be OK

I have the marvellous freya passive which seems excellent. Be happy to pop round one day and try in your system
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down

Excellent , nearly got a khozmo recently but not enough inputs . The freya has loads and several for too. Let me know when arrives and we can compare

Please note that when passives work well, they're transparent to the source as long as the source output impedance is low and the amp input impedance fairly high, but some power amps don't like them and response errors and HUM can become an issue. Fancy attenuators tend to look and feel nice, but I'd check with a standard film pot first before shelling out hundreds on a posh Khozmo. It's not quite as cut-n-dried as it would seem and the pot value can make a difference to either source or the amp it's used with.

Hi David, so if enjoyed the sound of my Tisbury Passive much more than a recent active tube preamp I acquired and quickly moved on I might not necessarily enjoy the sound from my new BTE preamp? I've given Mr Cresswell details of my source and power amp equipment and he seemed to think it would work nicely. I must say I will be mightily disappointed if it doesn't at least match the Tizzy. My guess is that it will or at least I hope it will.

Thanks for those salient bits of advice . Not had passive amps for some years while using modwright. However rather attracted by the freya as has valve and passive options . There is not huge differences but the passive is deadly silent and valve stage occassionaly gives a small bit of hiss or noise depending on which system I am using it in
