I'll try 1000 ohms, along with a few others, over the next few days, but I've now switched back to 10 ohms and am loving it. I hear more details, many of which I've never heard before, and the 'electronic sound' has largely disappeared. Now, would the dynamics be compromised by the cartridge itself or the electronics trying to amplify the signal? If it's the latter, that may not be a problem, but please correct me if I'm wrong, as both my preamp (Spectral DMC-20) and amp (Spectral DMA-180) are capable of very high currents.
