Advice on pre-amps needed


Just bought some new stuff (Audio Aero Capitole II; Ayre V-5X evolution and Electraglide power cords). Now I need a very good pre-amp with phono option. Which one should I take?

Nagra PL-P / Aesthetix Janus / Ayre K-1X evolution / CAT Ultimate SL-1 MK II / Cello Encore 1 Ohm ?

Any hints are welcome..Thanks!!

Just for the last few posts, hope you all realize this was a thread from 2005.

Your Aero has 5v!! output at 100ohms output impenance with it’s own analogue volume control with the remote, this is by far enough to drive any power amp direct (most only need around 1.5v for full output!!), and you’ll have far better transparency and dynamics and less colouration than any preamp could hope to have.

Go direct and save fortune and get a better sound by not having an expensive preamp in the signal path.

If you need to have multiple input switching the get one of these

And get a separate phono stage with it’s own level control, like these or better, depending on your love of vinyl. And put it through the Goldpoint switchbox as well.

 I would not suggest limiting yourself only to preamps with the onboard phono stage.  Your options open up a lot more if you go with separates.

It does and a very good one, read my post above yours.
