I koji su utisci nakon detaljnog slušanja?

Misljenja su podeljena.

Meni to lepo zvuci ali nisam zainteresovan za otkup. Ucestvovao sam u GBu iz drigih razloga. 

Nisam bas nesto spretan u testiranju i opisivanju, mogu da kazem da nisam uocio da bilo sta fali.

NOS 24/192... DDDAC2. Jes malo skuplja vatijanta....

Jeste skupo, još je i poskupelo, a Kinezi prete sve jeftinijim DAC-ovima. Kad sam ja to započeo, ima već  više od 3 godine, boljeg nije bilo za DIY, danas nisam siguran. Jedino ako baš želi NOS DAC koji daje mekši i fluidniji zvuk od ovih sa filterima i oversamplingom. Tamo su ga reklamirali da svira kao gramofon, naravno to nije tačno jer ništa ne svira kao gramofon, ni mnogi gramofoni ne sviraju kao pravi gramofon nego kao mp3. I gramofon ne može nikako da ima bas kao dobar DAC zbog poznaih ograničenja.

Sa hi-res materijalom 24/192khz preporucujem non oversampling dac, sto manje digitalnog procesiranja dac ima bolji timing (ispravna ritmicnost i brzina izvodjenja podseca na gramofon) ali je i dalje tesko izvuci tonalno izbalansiran zvuk (tu je dobar gramofon bolji od vecine dacova). Cak i stari 16bit dac cipovi podrzavaju ovaj i visi sempling rate, jedino sto ce odseci deo bitova sto cujno nije neki problem jer je jako tesko iscediti toliko dinamike u analognom delu. 

Izabrani dac cip je vazan (koliko i izabrana lampa u ampu) ali je uvek presudna realizacija. Sa istim cipovima sam slusao nebo i zemlja realizacije, od konfekcijskog nivoa do ozbiljnog audiofilskog uredjaja.

ja trosim wolfsona8741 vec neko izvesno vreme, odlican dac converter, u diy varijanti naravno, sa izlazom se igram malo, stavio  sam burbrown operacione, dosta boljitka u zvukusam dobio ,  u planu su sparcosi ili bursoni.U prvih par meseci mi je bio spojen sa kompom preko usb -a, ali....kad sam presao na spdif konekciju, tek tada sam dobio pravi zvuk, ja imam m2techhiface, i tu se ima mesta za napredak, sto boljo usb to spdif konverter, to bolji zvuk....sve u svemu, ja sam u mom sistemu resio pitanje zvuka sto se tice dac convertera......WOLFI !!!!!

Ja se (ponovo) vratio na Cambridge Audio CD 3. 

Dakle, 16 bit x 16 oversampling - na mesto ubiva sve ostalo u vezi digitalije do xyz k+ evara. :jump:

Nema dalje. :)

 it's close enough to the analog source to confuse me as to which is which. You sit on the couch, stroking your beard, musing that what looks like and prices out for the Pro Audio market, is really anything but.

There is little on the DIY or Pro forums about modifying the unit. The DECware mod addresses just the DAC section. Lampizator tried converting the DA-3000 ADC section to tubes, but doesn't appear to have productized the modifications. In any case, the above mods are within the reach of anyone with good soldering skills and a spare afternoon.
