To keep costs down, this modification is done to the RCA, single-ended side of the player only. We can do it balanced for an additional $400
Adding a DEXA clock will run an additional $480.00
The 12-month factory warranty is covered on all modified players if they are purchased new. Modified customer units will have a one year warranty on all mod work performed.
Sonic improvementsThe unit is quieter. Black are blacker, resolving more low-level detail for better ambiance retrieval. The tube stage is now smoother with a more liquid midrange and more inner detail while at the same time being more dynamic. Transparency is much improved and you can now look farther into the soundstage. Images are sized better and more defined. Stage width and depth are both improved. Bass slam and extension are dramatically improved, with fuller weight and authority. The tube output stage sounds more like solid-state in this area now.
