Integrated Jolida, Xindak, Doge, MF


I currently have NAD separates c272 and c162. I am considering going with an integrated amplifier. Would the following be an improvement or would you take a different route (stay with separates)?

Jolida 502
Doge 6130
Musical Fidelity
Xindak v30

I have listened to the Jungson now for 2 months, fully broken in. It is not cold and lifeless nor harsh like some solid state amps. It is warm and detailed with an incredible midrange. For those searching for experienced insight, Google Troels Gravesen. He is a craftsman who hand crafts speakers, and tube amplifiers. Look under his section called Amps Turntables/Auxiliary Equipment. Aside from his insightful critique of the integrated, he also disassembles the unit with annotation.

Note: I purchased the 220v version from Cattylink for $1300 less than the North American authorized retailer. Then I acquired a quality step-down transformer for $145. My total cost was $1200 US.
Agree with Mcgarick. I was recently in a similar position as yourself, and decided to try an ARC tube-hybrid pre-amp. It worked beautifully with my Citation SS power amp!
