preamp for dartzeel amp?

...i have had many preamps and my current 'first sound'.preamp..linestage only..paramount mk ii ..designed by emanual go ..is ..by far..the best i have had..he makes 9..i think..models from about $6k new to $28k ..they are tubed with separate outboard power supplies and completely separate internal rt and lt channel hardware.go to their website...good luck

get a rowland consummate. i know it's old and cheap, but it sounds beautiful as well as detailed. it just doesn't thrust the music at you. just make sure it has the upgraded (most recent) line stage modules, which are far superior to the originals. also, you can pop the lid and adjust input and output impedences, gain, etc. without tools or solder. plus it's fully balanced from input to output.
if that isn't quite good enough you could get a synergy 2i,
with a third of the features and flexibility, but an aircraft aluminum case.
otoh, i am so opinionated these days maybe i shouldn't even suggest this considering the dartzeel is an $18K amplifier. but from EVERYTHING i've heard and read, the dart and the older rowland gear seem to be designed to do very similar things.
if the dartzeel preamp came two ways- with and without the phono stage you could probably afford it. but they make two products and are probably not going to make a third in the forseable future. which must be very frustrating for those who want monoblocks with at least 200W into 8ohms, or
a linestage, or a standalone phono stage. with all due respect to the musicality of their stuff, perhaps way to much ink is being spilled about them while other companies are making components that are just as good...hell, you could buy an old pass aleph amplifier and go nuts over how tubelike it sounds (couldn't you??)
...just my 2 euro's worth...

I tested darTZeel with NAGRA PL-P. It was so amazing.
