Post Subject: Not completely conclusive but the demonstrably convincingPosted by Romy the Cat on: 11/11/2021
Fully armed with my new knowledge I made today an interesting experiment. I listen Remedios as is this amplifiers running for 35 minutes and then re-listen them again in 2 hours. It was very very convincing, very self-evident but slightly not what I anticipated. I anticipated that I will see difference in compression but I did not and I actually was very surprised as initially, stone cold amplifier, did not sound like a compressed. It did not sound good at all but I very fast realized that it is not a compression a normal sense. Compression implies shrinkage of dynamic range but I did not detect that the call dynamic range was compromised. It was rather not the whole dynamic range was the problem but the problem was with any sustained note of any amplitude did not allowed another note to elevate over itself dynamically. It's means if I have some kind of pedal point at 75 decibel and then above it I have some event unfold which should go to 20 decibel up, then those seventh decibels were fine but the events which unfold above pedal point where not at 95 decibel but at 80 decibel. I certainly did not do any measuring I'm just talking about my feeling of what I heard. It was almost like an amplifier ran automatic microphone volume control. Ass amplifier begin to warm up this effect begin to minimize very dramatically and approximately in hour and a half this dynamic plato over sustained notes become converted into the very animated randomness. Also, all those spooky sounds spooky sounds, hallucinogenic sounds, side vision sounds, unexpectedly beautiful sounds and the rest of the Bermuda triangle crap did not show up until the amp was fully hot.
I do not know if it is a property of solid state amplifiers, this specific model or specific quality of older capacitors but this is certainly the case. I kind of experience bipolar disorder with this news. From one prospective I am very glad that I found primer which looks like might be manageable. From another perspective one of the advantages, I thought, would be that I can just flip a switch and run my audio. I do not think it will happening with those amplifiers. I was told that it is okay to run solid state AB amplifiers all time. I was also told by the people who use SIT amplifier for a long time that it is not good idea to leave them on all time as they have a tendency overheat and faile output transistors. I certainly have a lot of options on table...
