Hifi-fine-tuning / some little thoughts / external 5V – XMOS-bridges (“Skysong” here)
today some little thoughts about hifi-fine-tuning here..
as i´ve ordered again some “green” “SMPCB V1.07” (its the fourth meanwhile, burnt one as testing out some dual dc ;-( ) and as i´m stuck now to buy some new bluray-player (for hdmi to i2S) i´ve reactivated my Skysong XMOS-bridge (http://essabre-90xx-rpi.sfb2.com/?p=1883) ->I2S->ES9038Q2M (green V1.07) to get some hifi “with ease” (from PC)..
cause i´ve got a little trouble at higher-resolutions (24/192) i´ve feeded the xmos-bridge (think its the same with all of them) again with an external 5V power-source, et voilá, again such a great difference to the usb-powered thing (said a lot about it in the above mentioned blogpost)->really again 10-15% better tune, hifi-began 😉 , means the music “disengages” from the speaker..
okay, and as i think my new Mission LX-2 are very “roomy” + “light”, i´ve got sometimes the feel that the old Mission 780 sound a little bit more “hifi” in some cases; they seem to be more “vocal”-focussed..
to “compensate” this i thought i change the standard NE5532 to my “heavenly” AD797ANZ (http://essabre-90xx-rpi.sfb2.com/?p=1693) as they have these unbelievable room, and some 3D-ish at their own and correspondent absolutely perfect with the sabre-chip-characteristica->”..i think the speciality on these Sabre-Chips is this digitally room/3D-feeling + also with the great soundstage..so i stay, as said, with the AD797ANZ“
(we had a schematic of the recommended op-amps for the ES9038Q2M, also with greater dynamic + thd/dnr etc..))->
so, i´m listening right now to these “combo” with the “heavenly” AD797ANZ (although i think they sound also a little bit “distorted”) and try to get the best out these special (what i like so much) roomy/3D-ish ess-sabre “hyperstream” technology (and to find the right speaker + amplifier for it)..
will post more in future, stay tuned and have a nice “happy new year” !! 😉
