Raquel raises an interesting point about the problems associated with both types of pre-amps and power amps when frequent electrical storms, i.e., outages as well as possible strikes by lightning, occur in your location. Is that reason enough to choose tubes vs SS? Is it true that tubes come up to an optimal operating status quicker than SS devices after power is turned off and then back on? With more power problems, especially in summer peak demand periods, as happens with increasing frequency in the D.C. suburbs here in the Mid-Atlantic region, should this consideration be given more weight in choosing tubes vs SS? I do not have hours to wait before I can listen to an optimal sound after a long day at work.
