Here's my response to a similar post in AC......
"IME, one thing that stood out between Bolder's SB3 digital only mod versus stock SB3 digital out is details are presented without glare & because of this, more of it can be heard as well. As I start to break in the Bolder's SB3 unit, the perceived soundstage began to widen, has greater depth & the LF tightens considerably.
FYI, I was using a modded Rotel 1070 CDP (Superclock II, DBE digital output, Rubycon's caps, deadening damping sheets & diodes upgrades) before it got replaced by the SB3s feeding digits to a DPA DAC. Based on a scaling of 1 to 10 (10 for best), I would rate the stock SB3 to be 4, my modded Rotel CDP/transport 5 & Bolder's SB3 digit only mod to be 7. The SB3s are being powered by Bolder's Basic Rev.1 PS for this comparison.
The Ulitmate MKII PS are more of "macro" improvements ie: providing more life to the finer/"micro" improvements of the SB3 unit digtial mods.
Hope this helps & make sense......"
