Most consumer level surge protectors have MOV or zener in parallel to the current. Which ones have thyristors in line?

Probably, as you imply, that thyristors are used (with zeners) in industrial applications.

I would take the benefits of protecting my expensive gear from power surges over whatever slight differences in dynamics are claimed to exist.

I don't disagree. My computer is staying on my surge protector even tho it powers my dac. But it was noticeable enough that I don't have my amp plugged into it anymore. But my amp is significantly cheaper than my computer lol.

Well I’m not an electrical engineer but with amp connected directly to wall I feel at the time of surge it will enter Amp first then via RCA cable to your DAC and then via USB to your computer unless you are using optical from your computers or USB in the DAC is galvanically isolated. So if you keep one component connected directly to wall there is a loophole for lightning or other unwarranted cause to do damage.
I may be wrong but someone with good electrical background can chime in

Not an engineer either, I'm pretty sure nothing can save your equipment from a direct lightning strike, but other surges caused from things like blown powerline transformers and the like can wreak all kinds of havoc.

I'm not an engineer either, but I'm pretty sure if you get a direct lightning strike you'd be dead so I'd probably not worry about your equipment LOLLL jk jk.

On a more serious note, I tried to switch to a non surge protection power power bar. I didn't notice too much difference, or at least if there is difference it's probably too small for me to notice between the changes.

So I'd imagine this could vary from power bar to power bar. Maybe some influence more heavily some a bit less. Let the power bar rolling commence!

Oh what I did notice is that I've been using the ES9028 card, so I got an iFi Zen Air Dac as gift over Christmas. So I'm like hey why not, so I plugged it in to the PMax through RCA. I think I might actually like this more than the ES9028 card, need to test more. Only thing is I find the Zen Air Dac has smaller soundstage for some reason. Will test more....

Through another random turn of event, I picked up a MMB2 because someone was selling it so cheap that I can't refuse. So will update you guys next week once it arrives.

Now I started using RCA input, I noticed the volume knob hum when my hand is touching it. Using the dac card it was completely fine.

Anyone know how to get rid of it?

Oh lord, please no.

I just can't see how it makes any difference, because most power bars put nothing in series with the mains current. And the dynamic current draw on the mains voltage side of a headphone amp is incredibly low - especially when you consider energy stored in the transformer, reservoir caps, regulator drop-out, and quiescent current through the output stage.

So what sources and headphones is everybody using?

Yea, I do hear a difference. But it's probably not a good idea either way. The rewards are not worth the risk. A lightning strike would kill it, surge protector or not tho I think.

 

[Rattle]

I'm using the following with this amazing amp. Bifrost 2 and PI2AES/PI4 using coax/BNC. Playing all lossless files. Headphones are JAR650, Atticus, HD6XX, HD600, need to try Elex when I have more time. Also have the ess card on order.

I plug it all into the same Furman EMI/RFI/Surge protector. No hums no buzzes or vibrating knobs.

I'm anxiously awaiting my Audio Note DAC 2.1 signature I just bought. Will replace Modius E.

Oh! Do let us know!

Thanks I will. Tube output stage and
tube rectified. Anyone wanna buy a Modius?

I have the Audio Note kit version of the same DAC. Very nice it is too.

However, my Modi Multibit has its own strengths.

Yeah I had a BF2/64 that I had to sell earlier this year. I really thought about getting the Yggy gs2 for about the same price. But the AN appeared in the classifieds and figured I'd try it out. What tubes are you using? Mine is coming with stock and tung sols.
