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

The more I have researched, the less interested I am in tube amplification. The sound quality of tubes are appealing. However, I just am not committed to the hands-on maintenance of the equipment. Someone had recommended the Jungson JA-88D integrated.

I listed primarily to classical (light classical, sonatas, chamber), big band.

My equipment: VPI TNT jr, 12.5 tonearm, Jasmine 2.0 Se (just acquired), DIY Orca Designed TMM Focal speakers (ported with a pair of 7" W-cone mids, and Focal Audiom TLR tweeter). They are floor standing models. They seem to be efficient and very balanced, soundwise. Room is carpeted, 19 feet x 29 feet (listening space is across the short side).
I acquired the Jungson JA-88D. What a great integrated for a reasonable price. It is extremely smooth, detailed and powerful, with a deep soundstage.
i owned a jungson 88 integrated. traded it for a 50wpc el34 based tube integrated, the result wasn't even close. tube all the way.
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.
