Best Sounding Passive Preamp

I bought 20 kits of parts from luminous after trying their pre-amp. Used with a Naim NAP250 & AVI Monoblocks.
Inside there are just two Caddock resistors & one 10K Noble Pot. The resistors are 2k87 ohms. The rest is a box, wire & 4 phono plugs. ( Must use Caddocks for best sound, we tried all the others, as was the case with the Noble pot)
Cost to buil DIY is about £20 max. Only suitable for line level, CD etc. Just perfect, clear, deep bass but controlled & beats active pre-amps if driving direct from a CD.

Deradave, try buying or building an LSA DIY - no pot better than no pot. Not the killer value of your DIY, but I think you will find even better performance if you can believe it.

I notice the consensus in the Agon chattering class is the TVC/AVC "kill" resitor based passives. Not my eperience, but I do wonder what a TVC/AVC would be the better approach, there obvioulsy some systems that would be better served by some impedance matching provided by them.

Bent Audio Tap-X

BENT was the best of all I tried, till I tried the LSA, but certainly at the pinnacle of passive options, and likely the best TVC (like the AVC even better), plus a lot more flexibility than the LSA which is a little hairshirt, but....

Pubul57,

Interesting. I purchased the LSA recently and have been A/B'ing it against the Tap-X. It is very close but in my opinion I find the Tap-X has slightly better drive in my system at least and produces a more open soundstage.

Are you running very short interconnects between the LSA and your source and between LSA and amp? Would be interested to hear your thoughts on how to get the best out of the LSA.

Thanks
