Hifi-fine-tuning / some little thoughts / external 5V – XMOS-bridges (“Skysong” here)

so,  😉

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” !! 😉

essabre-90xx-rpi.sfb2.com / registering not possible at present..

so folks, 😉
sorry about it; but “registering” is not possible at present; but u can still leave some comments via the comment-“button”..
by that i/we have a great “hack-attack” and so i have to delete a really great amount of “false-user”; it could be possible that your account will be deleted too..
i inform u if registering is functional again..
by that, outgoing mail is also not possible at present (for password-resetting and so on)..i work on it, but it can last a little bit longer..
kindly excuse any inconvenience !!

greets for now !! 😉

The AD797BRZ arrived -> more “dark”-sound, more in the back/laid-back..

so, 😉
finally the AD797BRZ arrived here (all following is under the “premise” that i´ve got original (or near to) ones and not cheap “crap”)->absolutely more “dark sound”, absolutely more push in the lows/middle-lows..
(as presumed->”the BRZ were the ANZ with all the advantages of an OPA627AU..”,”its like going from digital to vinyl”..)..
absolutely okay, high THD+N, very “exactly” , very good Op-Amp, but for me absolutely too dark, not soo much presence (at all and in the middle-highs/highs..)..


(but also said: i have got not the time (and fun) at present to get more in-depth with the BRZs)
after replacing them with the ANZs:->thats for me the right direction..
get so a better idea of the “true/right” sound..(for me)
(i really miss the “brilliance” of the AD797ANZ (in any case from the ones i have here)(although, as said, i also miss the “push” in the low/middle-lows))..
but all this depends very much on your other “gear”, speaker, amplifier, room-size, listen-preferences and so on..
so, conclusion:
i will stuck here with the AD797ANZ for now (on the “blue” ES9038Q2M)(all according to, as said, that i´ve got the original (or near to) OP-Amps..; i would prefer them over the NE5532,LME47920,OPA2134,LME47910,Muses8920,OPA627AU->(in this order)(see this post in the forum->LINK)
but again: it really depends on your personal listen-affections and so on..
in optimizing the ES9038Q2M the next steps will be (without some hw-modding;its too complicated for me at present): connect a -+15V toroidal transformer, buy some (as last op-amp-step) Burson V5/6 and maybe use an AK4137 (see earlier posts)..
and (“quelle surprise”): buy finally some new speaker+amplifier 😉

but many greets for now (+ more to come)!! 😉
