Hi Jeff,
but right off the bat, the sound is much more dynamic, with more bass weight and a wider soundstage. But the big bonus is the quiet background.
Thanks for posting your initial Black Lightning impressions!
You are certainly using it with some really high-end gear, and I'm glad you are using it with a phonostage:
A phonostage takes a very delicate, low-voltage signal and has to boost it to a line-level signal (so there is a lot of gain involved, 50dB or 60dB for MC is not uncommon) - so a clean supply is essential for this application in order to not boost power supply noise along with the low-voltage signal from your MM or MC cartridge.
So this is a good test for the Black Lightning! The BL also offers much higher output current (much lower output impedance), so better dynamics and bass weight you report are to be expected).
Also try it with that Wadia iTransport cable I sent you - I have, and BL clearly makes it a much better sounding transport. The stock switch mode supply for the Wadia is dirt cheap and very noisy - it does not do the iTransport justice...
I think I need another one for my Nagra LB digital recorder!
Your Series 10 Black Lightning will power your Nagra LB recorder for over 24 hours - I'll make you the cable (just let me know the required DC power plug). Clean power is very important for clean recordings - so this will be another great test of what the BL can do!
Looking forward to the full review, and thanks again for posting your initial impressions.
Have fun!
