Mora da pogledam po fijokama. Sigurno imam negde.

Pa i za PCM63P imam potvrdu u sobi. A uskoro će i još njih da ga ima u sobi. Jedno 8 njih. Pa nek upoređuju sa gornjim TIER list pa nek pišu utiske. Ene, da li sam se ja odjavio odavde ? p.s. Nemojte da mi šaljete više na Vajber da dolazim ovde molim Vas - nemam vremena - jedva stižem i Vajber poruke da vidim trenutno.

U krajnjem slučaju nije ni bitno - bitno je da piješ svoje piće - svojom rukom napravljeno. Za početak aparat za destilaciju napraviti. Pa svoju burad. Pa uzgajati voće....itd...itd... Svaki gore čip će da zvuči jako slično na Miro PCB. Sve vuče na istu aromu buradi.

TIER 1: PCM63 The best sounding DAC with the smooth in all frequency response, great depth, large soundstage, very good details and very intimate sound is only achieve with this one and the only PCM63 DAC. The music played from this DAC are full bodied, every stings stung and all musical instruments deliver with emotional and passion. No others DAC can achieve this top tier list except this PCM63. TIER 2: AD1862, AD1865 They are both have similar sound signature. Lots of details, great soundstage, good depth, very balanced sound quality and nice sounding vocal. The AD1862 slightly better on mid-range than AD1865, but you might hard to spot the difference when both DAC are test using ABX method in listening test. AD1865 is very easy to build and still easy to obtain these day. In contrast, AD1862 is one of the rarest DAC IC after the PCM63, yet very hard to build since it need 4 separate power supply for each IC. TIER 3: PCM1702, PCM1704, TDA1541 I put those DAC as the third tier because they have their own weaknesses compares to above tiers. Lets say the PCM1702 and PCM1704 shared the same sound signature. Both of them have very wide sound stage, great details and speed. But both of them sound more analytical, more dry and thin especially in the vocal. In contrast, the TDA1541 has very good midrange. Very forward midrange presentation (can be good or bad, depends of the listener preference) with multi dimensional, multi layer depth of vocal sounds. But TDA1541 lacks of details, narrow soundstage and mellow. It is very opposite to the PCM1702 and PCM1704. TIER 4: PCM56, PCM53 They are both the oldest R2R DAC from the same company. They also have similar sound signature. Both of them are sound good especially on the midrange, but of course not as good as TDA1541. This PCM56 and PCM53 have a good detail but narrow soundstage. Those DAC have many weakness especially on the sound presentation is lack of dynamic and the high frequency are slightly noisy. But they are both much better than any delta sigma DAC I've also mentioned above. For the PCM53 is slightly better than PCM56. TIER 5: TDA1543 Smooth midrange. That is the only strong points of this DAC. All frequency are dull and collapse. The soundstage very narrow. No detail. I still think that TDA1543 is a delta sigma DAC but in more simple/ less number of the current converter (Dynamic Element Matching) architecture. Those are my thought about the sound quality from each vintage multibit R2R DAC IC that I've ever built and experienced. Those are the most popular multibit DAC IC that have a good sound quality reputation among the audiophiles.

Opet me forum pretplatio na postove

Zato što je prodao Y

Mene samo zanima tvoj I/IV all jfet kosher kako izgleda. Odnosno Erno Borbely edition DAC.
-
Da nisi i ti poludeo da praviš ovo ili mi se priviđa ?

Nisu skupi i lako se nabave preko mouser. Jedino je lemljenje smd komplikovano. Meni je bila zamisao da svaki segment ima odvojeno napajanje i galvansko odvajanje. Xmos --- Xilinx ---- Sifteri + digitalni deo DAC ---- analogni deo DAC --- analogni izlaz. sve ukupno 5 napajanja i dva trafoa. možda je overkil i preterivanje ali to sam ja

I ne zaboravite da apdejtujete JLS odavde - ko je kupio pre August 2022 http://jlsounds.com/updates.html Čini mi se da još bolje peva sa novim firmware
-
Brži jesu šifteri ali čujno nema nikakve razlike. Niko živ ne čuje razliku između 3 i 20 nanosekundi. Miro kaže da je svejedno. Ja mislim da je bolje sa šifterima jer i oni imaju odvojeno napajanje.

Molio me @skrstic preko bibera da stavim ovo ovde https://www.diyaudio.com/community/threads/dac-ad1862-almost-tht-i2s-input-nos-r-2r.354078/page-27#post-6288946 https://www.diyaudio.com/community/threads/dac-ad1862-almost-tht-i2s-input-nos-r-2r.354078/page-127#post-6828113 https://www.diyaudio.com/community/threads/dac-ad1862-almost-tht-i2s-input-nos-r-2r.354078/page-112#post-6692625

ovo bre 09P-102J- paralelno sa Silver Micom
-
Jedino mi nije jasno na gornjem uredjaju sta ce mu Choke od 1mH paralelno sa onim otpornicima na izlazu

Pogledaj deda iz PS audio šta je stavio u njegov PCM63 DAC pumpaju trazijente kao nenormalni
-
Sviraju umilnije na uvo. Na merenjima je suprotno.

Pa nije mogao ni ćale da nabavi Y - možda za sebe samo
