Thank You, the effort to write. V-Cap OIMP are wholly decent capacitors but I think its worth it to change with Mundorf. It seems that Mundorf Supreme is the cream on the cake..
These days I felt a real difference to the sound, very nice: an extension to the entire frequency spectrum, a better position depth of instruments (audio-layering), higher decay and obviously, a more refined texture of sound! The voice, the instruments have body and better stage presence than before. On the electrostatic headphone system, the transparent sound (life-like feeling) and details are outstanding!! I think this is due primarily running-capacitors and probably Shinkoh resistances have evolved inside the dac.
However, they do a very good game with Schottky diodes.
The R-Core transformer is on the way..
PS: To give Havana a
"high-end touch", after you finish with all the changes inside, I recommend you change the stock RCA connectors with WBT Ag (Ms Metal nut) pure silver and DH Labs silver hook up wire. Is also important the change of stock input SP/Dif with BNC conector, to get a slightly better impedance. The source and transport are again,
very important!! I am extremely pleased of the work done AR-T Legato and iMac Apple with audio player that runs on Macintosh.
Legato contribute decisively to articulate the bass, down to extremely low; low frequencies are so well controlled quantitatively and qualitatively, played convincingly. The sound is
very relaxed with Legato and has a similar play analog sources, beautiful and natural. But probably the decisive question of a transport capable of extremely low values of jitter is something that bears audition to another level of quality: is the natural expression and the unmistakable perception of audio-layering! Without doubt, Legato is capable of playing audio layerin's such a level.
I wish you pleasant listening!
