When I saw that Grover was making a power cord I had to give it a try. I'm using a Modwright LS36.5 preamp, but at the moment can't afford the additional cost or hassle of a second box for its add-on external power supply. With the beefier power supply out of the picture, I was thinking that maybe the Grover power cord could improve the power and take the performance of the LS36.5 up a notch.
After the obligatory burn-in period on a different system, I swapped in the Grover PC and heard improvements in (1) bass response (stronger transients), (2) definition (voices already fantastic with the LS36.5, but now instruments popped out with greater definition), and (3) speed (the whole system is more dynamic and fun to listen to).
I don't know how power cords make a difference, but for some reason they do even with my dedicated lines and running springs power conditioner. I have made some comparisons between the Grover, Audience Powerchord, TG Audio 688, and Wasatch Cable Works (split off from Kimber Kable).
I love the Audience on CD players as it significantly broadens the soundstage and improves definition, but on the LS36.5 it made everything sound etched and less musical. The TG Audio gives extra zip to power amps, but didn't have much impact on the preamp. The Wasatch Cable PC is very good on the preamp offering up a very balanced sound, but by far the Grover is my favorite on the preamp because of the extra life it breathes into the system.
So, I'd say the Grover PC is a winner and recommend giving it a try. The power cord itself is easy to work with, not stiff, but not a noodle either. And it is terminated with some very nice Furutech ends.
