Upgraded Transport + Feet
This is a job for the professionals, so plan on sending the unit to your dealer (or the factory) for them to accomplish. The original feet were just some simple plastic jobbers found on any low-fi piece of equipment, but the new ones are obviously machined and have a non-resonant filler within them, and are more befitting a component of this quality. However, the discussion of feet pales in comparison to the discussion of the transport change. The original transport, an OEM from Philips, was replaced with a (more or less) drop in substitute of much better quality. While still not up to the heroic construction standards of a VRDS transport, the new unit is one for which no apologies need be made. It has the look and feel of a solid drawer, with much greater rigidity to any twisting or vibration.
The differences were not subtle, and I was not struggling to hear them. As I wrote in my original review, the CDSA got negative marks for bass depth and impact that was not up to state-of-the-art standards (as defined by the Esoteric XO1-D2 in my experience). Well, the new transport made significant improvements in just these parameters, allowing a drum kit to extend lower and with a greater percussive feel. Additionally, while I was very much pleased with the leading edge of the stock unit, feeling it defined the attack without the overemphasis often found in inferior players (a characteristic which, along with an elevated treble balance, gives rise to "digititis"), the upgraded transport gave a bit more snap to the leading edge. This is a point worth elaborating on. In comparing solid-state amps and tube amps, I've found the former to emphasize attack and linearity while the latter emphasized musicality, but it was seldom the two in equal measures within any component. Prior to the upgrade, if forced to I'd have categorized the CDSA more on the "tube amp" spectrum of the above continuum, but after the transport upgrade, it is now more evenly balanced, treading that rare ground that gives rise to both the attack and the musicality. In other words, the unit has seen its sense of PRAT (pace, rhythm, and timing) improve quite significantly, while still maintaining that tonal truthfulness that made the CDSA such a godsend for vinylphiles and others who abhor the sterile sound of digital audio.
An additional improvement that was easily predicted from the use of a sturdier (which can easily be read as "more resistant to vibration") transport was the ability of the unit to extract even more details than before. Given how good the original unit was in this regard, I was surprised to hear those additional low level details that were heretofore obscured to me. What was interesting was that the net effect of this was greatly improved imaging and soundstaging. And this makes sense when you think about it. When you add detail, you're really adding information both about the performance and the venue of the recording. The unit has always gotten the performance and the venue, but the lowest level details are in the reverberation of the studio / recording hall, and extracting this information helps place performers in space.
Taken as a whole, the upgrade to the transport has taken what is arguably the finest single-box digital player up another notch or two.
确实如此。转盘换过。
但我知道的就有不少cdsa转盘维修的案例，只是没注意是否黑牌。 |
