Nisu skupi i lako se nabave preko mouser. Jedino je lemljenje smd komplikovano.

Meni su obavezni shift registri. Nisu skupi, već sam ih poručio i hoću da imam I2S vezu zbog SPDIF i TOSLINK ulaza. Ako tako bolje zvuči (sumjam u to) još i bolje.

SMD lemljenje komponenti ove veličine nije mnogo komlikovano sa lemilicom, puno fluksa i malo pažnje. One sitnije bi ipak teško zalemio. Morao bi prvo malo da vežbam.

Da nisi i ti poludeo da praviš ovo ili mi se priviđa ? :msn-rofl:

sta mogu kad me oce, ene stize poklon iz Amerika sledece nedelje

:smesna:

ono, to cu crtam kad sam zaludan, zabave radi

a sto rece nixie za shiftere, a sto mene ne pade na pamet - ako ocu vise ulaza (USB + nesto + nesto) onda mora da koristim shiftere

iskoristicu Pavouk PCM1702 za pamet, a ostalo cemo slazemo okolo sve na jedan pcb, milijardu shunt regova malihmalecnih

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.

Ne mozes uzimati tudji tier list za tako nesto :) Ja volim rakiju od sljive vise nego viski, gomila voli viski vise nego rakiju, a ima i onih koji se tripuju da je viski superiornije pice pa se loze da ga vise vole 😂 Suma sumarum, retko sta moze objektivno da se gleda :)

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. :drinking-2:

Pa i za PCM63P  imam potvrdu u sobi. :loleverybody:

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.  :sarcastic_hand:

Imam malo i iskustva u tom segmentu, pravim svoju medovinu, vino i rakiju 😁 Ali i dalje mogu da kazem da sam probao bolju medovinu (schramm), kao i da je artisani sljivovica premium ukusnija. Sve je stvar ukusa, i treba biti objektivan u subjektivi 😁 Dok ne cujem i jedan i drugi necu moci reci sta mi je bolje.
