I’d go with Cullen too, although I recently heard about Audio Envy that also sounds very intriguing. Most of these guys offer a return period so you can give one a shot with very little risk. Given the quality of your preamp I’d recommend you at least try a better power cable as it could potentially make a big difference for relatively little extra cost. Best of luck.
I wouod like a power cord recomendation that's in the budget category
I have just purchased a new to me from Audiogon an Aesthetix Calypso pre-amp and would like to see some power cord recommendations. Something not too expensive that is known to work well this this piece. $350.00 budget, spent my stash on the new pre.
