Preamp... Solid State or Tube

I am looking for 2-ch preamp that must have HT bypass option to mate with my existing HT processor.  

My budget is 10K for this upgrade.  Couple of preamps comes to mind but I have no experience with these components.  

Ayre KX-5 Twenty
Aesthetix Calypso 
 
My system consist of following components, 

Speakers - B&W 800D2
Source - Aurender N10,  Modwright Elyse DAC, Raysonic CD-128
Amps - Modwright KWA150SE (Pair of them being used in bridge mode)
Processor - Krell 707
Cables - Verastarr Grand Illusion Statement and Signature series

Any recommendations will be highly appreciated.

Back to preamp, I am looking for fully balanced circuitry from input to output.
You've not mentioned if you need a phono section.

Our MP-3 (which is fully balanced-differential and all-tube) would fit the bill and is known to work quite well with the Modwright amps. There is no HT bypass; you merely set the volume control to a particular position (which is essentially what the HT bypass does) and you are good to go.

Lalit, a point to keep in mind is that the input impedance of your Modwright amps is specified as "Min. 15K at 50Hz; 23K at 1Khz."  While it's not made clear in the manual if that applies to the unbalanced input or the balanced input or both, some tube preamps will not perform at their best when driving impedances that low.  Including the Calypso you mentioned in your initial post.

Atmasphere preamps, however, will certainly have no trouble dealing with such an impedance.

Good luck.  Regards,

Are your plans to pick a preamp sight un heard and never look back ? If not just start the process . If you are going used the market availability will decide your options . One full proof way of getting a match is to first go with same brand as your amp . Or just see if one brand comes up more than others here ? Great way to pick a component !

Almarg: Can you describe the impact on the sound of using a higher input impedance amp such as the Modwright and a linestage that would like to see less impedance?
