I am upgrading my 501 this week.
@agisthos I agree. |
@celtic66 Thanks for that. There is only one upgrade and that includes the "4 channel part". I don't like the name because it's confusing and you still end up with stereo outputs. What they are referring to are additional internal DAC chips. So you have it all. I've heard the same from others with the "4 channel" version; not a huge improvement but definitely audible. |
Yes. I did upgrade. Not for the 4 channel part, but for the upgraded chip and upgrade of the analogue section. Installed by Tom at Big Ear Stereo who liked the upgrades from a technical point and correctly predicted improvement. I hear improvements in definition and dynamics. Not outrageous improvement, but palpable. I do not know if it would be discernable if not for a high threshold of a system. Hope that helps. |
