Extension cord advice
There are two major features of a Furman I recommend:  LiFT and SMP.  This unit has both in the smallest possible form factor.   https://www.amazon.com/Furman-PST-8-Electrical-Extension-Connector/dp/B07GRCMT37    
Your system struck by lightning? What did you learn?
Re-upping this since the south is  going to suffer severe storms today and tomorrow.

My thoughts are that you are not describing the problem nearly well enough.  
Dc voltage sent to my speakers
@atmasphere  My experience with tube preamps is very limited, but the one or two that I played with had a tiny bit of DC on the output.  In the range of 5mV or less.  
What news in 2023 struck you?
@phusis - I mostly agree with you.  Given how inexpensive the internet and disk storage has become a super high compression algorithm for music seems like a waste of effort. The one area where I believe we do have a need for something like this i... 
Eliminated my preamp with amazing results
This brings up the question..."what is the function of a preamp?"   A very good question, @gdaddy1 which you almost answer completely, but I’d say a little off. Besides source selection, a preamp’s jobs are: Level MATCHING Impedance MATCH... 
It's attention, not money, we should budget
@waytoomuchstuff    Kind of.  The thing is though, if we open ourselves to DIY then that calculation does change a little.  I don't mean just speaker building, but say, DIY your room and acoustics, or cables, etc.  We may spend more money on ou... 
AV Processor Conundrum
My experience with the recent crop of Anthem gear has been mixed. It doesn’t do Dolby Surround correctly, it has noisy outputs and lacks the ability to manually dial in EQ curves fully. Also, the room correction just doesn’t work that great for me... 
Is toeing speakers a bad idea?
The off-axis response of the tweeter + the room are the balancing acts. I do think the idea that all speakers need to be laser calibrated to point to the listener is a myth we should deal with more. The correct answer IMHO is balancing your prefe...

Should also note that SS amps also may suffer from small imbalances, usually under 0.1 V though.  
Dc voltage sent to my speakers
@ketchup - Even with the best caps there can be some leackage, but usually in the microvolts ( < 1 millivolt ). Yes, it's very common for the output caps to leak DC and need to be replaced.  Not saying everyone's caps will fail, but that this ... 
Dc voltage sent to my speakers
If you want fancy amplifier output protection you need to stick to Class D.  Not really joking but looking at the Hypex and ICEpower spec sheets they have a lot of fault detection and shut down circuitry built in that most linear amps never even ... 
Dc voltage sent to my speakers
Oh, forgot one, often BJT amps will also have some sort of thermal runaway protection.  Otherwise, no I haven't seen a lot of SS amplifier schematics with "turn off on DC" on the outputs. But, I'm not a tech, just a hobbyist who stopped pouring o... 
Eliminated my preamp with amazing results
I'm always amused when members ask if they should/should not pull out a preamp because the answer is always a personal one. It's been a very long time since I've seen an impedance mismatch so large a DAC with a volume control could not directly d... 
Dc voltage sent to my speakers
Most solid state amps have a protection circuit to prevent damage to the speaker in case of output section failure Um, not the one's I've seen especially "high end" amplifiers that pride themselves on not having any. It varies a lot by make an...
