Leave an amp "on" permanetly

Mrtennis,
The Shunyata Hydra-2 is a good conditioner that also regulates voltage anomalies...which you seem to be experiencing. Many audiophiles also use the Richard Grey RGPC 600S and pole pig.

I have a dedicated power line with hospital grade outlets for my Threshold T-200 amplifier. This Class A amplifier runs hot, and the soundstage grows dramatically within the first two hours it is turned on. Same with the Audion and EAR859 tube amps. Even the old (1975)solid state Marantz 2252 improved after a couple of hours, although less dramatically than the aforementioned amps. On the other hand, I heard little difference from the lower end NAD and Rotel products.

Mcpody, Hydras do not regulate voltage anomalies. These conditioners are passive.To regulate voltage fluctuations you need a power regenerator. Hydra can be used with some amps as a conditioner only. But know that it won't regulate voltage.

i use ps audio noise harvesters. at night 4 of them are blinking. when the temparture is over 80 degrees, i really have a problem. air conditioners are in use,their is a greater demand for electricity and the sound often degrades.

perhaps a hydra or richard grey may help. thanks for your suggestion.

I tend to leave mine on, but have noticed the amps (jungson JA1/99C) sound slightly faster, but perhaps less warm if I don't leave them on overnight. My concern is the life of the capacitors may be reduced by the constant heat. Is this an issue to be considered?
