Pass Labs XP-30 vs Krell Evo 202


Hi,
I am considering upgrading my preamp and would appreciate your help in comparing the Pass Labs XP-30 and the Krell Evo 202. I am also interested in finding out how much of an upgrade each of these will be over my current Classe CP-50.


My current setup is,
Thiel 7.2 Speakers
Krell FPB 400cx Amp
Classe CP-50 Preamp
Esoteric X-03 SACD Player

Note: I have already tried a Conrad Johnson 16 LSII. I preferred the sound of my Classe to this unit in my system. The Conrad Johnson reduced the amount of detail at all frequencies compared to the Classe. The Conrad Johnson also produced images that are big and somewhat smeared together where as the Classe has space between the images. The Classe soundstage also had more depth and width.

Thanks for the input so far everyone.

teajay,
Based on price I would hope the Pass Labs to have the best overall performance. For each option, I am looking to compare the amount of performance improvement I would get vs the cost.You mentioned that you had heard the Classe, Krell, and Pass units. On a scale of 1 to 100, if you were to give the Pass Labs XP30 a 100, what would you rank the Classe CP50 and the Krell EVO 202?

randy-11,
I actually considered the Ayre KXR and from what I have gathered it has good performance. I am a bit concerned about trying it in this specific application with the Thiels based on what I have heard about its tonal balance. The Thiels are right at the edge of being to hot on the top end and from what I have read I gathered that the Ayre is pretty hot on the top end also so I am a bit concerned that It would not be a synergistic match for the Thiels. However this is just a hunch, If anyone has actual experience with Ayre and Thiel I would like to hear your input on this combo?

I am open to tube options. My last venture into tubes described in my original post ended up with me keeping the solid state Classe. One of the things i like about the Classe is that the images come out of a completely black back ground where as the tube pre I tried had a higher noise floor which could be heard throughout the soundstage. Also, I lost a lot of detail and the images smeared together with the tube pre I tried. If there are some tube options that can produce this black background, not loose the detail, and keep space between the instruments in the soundstage I am open to considering them.

lancelock,
I looked up the Liner Tube Audio MZ2-s and i did not see an option for balanced output. My amp only has balanced and cast inputs so I don’t think it will work in this application.

erik_squires,
What preamp does moves you to tears?

charles1dad,
I agree with you comment about listening. I would say one of the purposes of this tread is to narrow the choices to those most likely to be successful in my system and then step two would be to buy used the one that seems like it is most likely to get the desired result and listen to it as you have described.

4425,
Tell me more about what you like about the Phantom. My understanding is that the Phantom is the updated version of the EVO 202 i am considering. From what I have read here these units are supposed to sound pretty similar with the Phantom being slightly more refined.
