Tuning/Upgrade of my old Philips CD 650 Player | ||||
Zusammenfassung meines Upgrades:![]() ![]() ![]() PH CD650 - DAC & 1st filter PH CD650 - PSU & 1st filter DAC & Filter ![]() ![]() ![]() ![]() ![]() ![]() My current WNA MK II Headphone Amp project und reduziere die Last (Poti 10 kOHM entfallt) für den DAC Filter OP AMP. In Audio 09/2006 audio.de - Philips CD-650 wurde unter "Alte Helden" der Philips CD-650 beschrieben. Durch meine Modifikationen spielt er sicherlich in der nächst höheren Klasse! ![]() Die Veränderungen sind nicht spektakulär, aber in den leisen Hintergrundpassagen ist plötzlich eine Feinzeichnung vorhanden die ich so noch nie gehört habe. So z.B. bei Pink Floyd "Final Cut" hört man die Hintergrundgeräusche (in Q-Sound aufgenommen) trotz Kopfhörer einfach plastischer. |
||||
First Tuning/Upgrade: |
||||
Hearing test (with new cinch cable too) - WOW" its much more better than the original headphone output. With Eva Cassidy "Live At Blues Alley" and some other music all my hairs stand up, I have never heared this so before. The change of the cable resulted in much more detail, more air between the musical instruments; trap-brass detail - it sounds tststs as tszszs before (quick, short beats) - I feel the brass in front of me! Some of the special music I
heared too: |
||||
Second Tuning/Upgrade:
|
||||
Hearing test (short with
OPA2134 little more detailed) with OP275 - the problem I had (before bypass the 2358/2364/2359/2365 with 100nF it probable oscillate) is solved. The sound of the OP275 is analytic till to the highest tones (the OPA2134 sounds warmer, more musical). I hope for
feedback from other DIY's |
