at the end I explode the budget ;-)
after hearing:
Audio Research CD7 (very nice musicality)
Krell 505 (with newest preamp and monos with Magico V3 ... a catastrophy!)
Wadia 581 ( on the same system, more musical but the cable wasn't obviously a cast ... very slow mechanism!!)
Esoteric combi 03 (incredibly analitical with Viola preamp, Manley monos & Amati Palldium)
MBL combi (beautifull sound but too expensive, with Pass pream & monos with MBL 101 ... what a mistake! the bass desastrous)
EMM Labs single box ( maybe a little slow? Pass integrated with Avalon Sentinel ... waouh what a loudspeaker!!!)
Emm Labs combi (same system, incredible details coming out)
DCS P8 (very good with JR Capri + monos 501+ Avalon ascendant)
finally I decided to buy the ...
DCS Puccini ... analitical and very musical ... the perfect combination for my sytem
before having it home, I could listen to it on the Avalon Indra & Sentinel
