Needed a better stereo pre, the pt100 is good but still an entry level & on the brighter side.
Was looking at parasound P6, which has great reviews , price was high, at the same time got hold of a pre used emotiva XSP-1 (differential reference analog stereo pre) for a very reasonable price along with an ERC 2 cdp.
The difference in SQ is way higher now. The xsp-1 is absolutely smooth & in a different league. Matches the sonodynes perfectly.
Xsp1 & Erc 2 being both differential refference are going to stay in the main set up
