Basic surge protection with some noise filtering without strangling the amplifier?

I’m looking to get a basic multi-outlet surge protector that has some basic noise filtering and that has at least a few outlets for high-voltage equipment (amp in my case) that will not kill the sound of the amp.

Do those of you with practical experience and/or technical know-how think that that the Furman Elite -15 PF i fits this description?  (From its own write-up, it does.) Are there other devices in roughly the same price range (<$1k), that I should consider?

The amps in question are a JRDG 625 V2 and a CODA CSib.

For one data point of comparison, I tried plugging the 625 V2 into a Torus RM-20 and while the sound floor did seem improved (from already very quiet to even blacker), the sound quality immediately suffered a lack of vitality and dynamism. So, the amp is not connected that way any more.  The other upstream components (pre-amp, Roon Nucleus One, streamer & DAC) do seem to like the Torus though.

"Isn't "voltage regulation" one of the three pretty critical components to proper system protection and filtering/performance?
I only mention because the OP mentioned "....without strangling my amp"
Wouldn't stabilized voltage delivery be critical?
I have a neighbor who welds quite a bit, and my lights will dim a little when he's doing a fair bit of plasma cutting and welding."

The amp's power supply handles all that.

What ever device you choose make sure it is stated as a non- current limiting design.

I agree, @triton20trx. Certainly the Furman and AQ 707 discussed above make that claim.  i guess what i am asking is whether one should trust the manufacturer when they claim that?

Having good voltage is critical, but I find this really variable in terms of how many really need it.  Personally I use a Furman voltage regulator to keep my system within 5V all year long and regardless of how hard the AC is running.   I first got it because I was in a San Francisco high rise with 130V coming out of the wall!  Within spec but a little worrisome for me. 

While Furman AR (automatic voltage regulation)  is a lot more cost effective than say a PS Audio power plant, it’s still not cheap.  If you find your lights dimming from another home’s usage though you may have other issues.  I’d suggest getting a plug in AC volt meter and measuring how bad it gets.  If it’s bad enough your first call should be to the power company or an electrician. 

If it’s within spec then yes, a Furman with AR is a fabulous device which keeps your gear behaving optimally.

@kirkwallace I don’t know how you validate their claim except to research reviews to see if anyone has had problems.  If you don’t trust that claim in the product specifications how do you trust any claims.
