Good Inexpensive Multi Plug

Seeking some power advice...

Ive recently been adding some power options to my set up. Moved from a cheapo 12 outlet multi plug with filtering/surge protection to a Tripp Lite Isobar 6, and found some definite sonic improvement. Experimented by removing everything other than amp, dac and source...marginally better still. Then moved to plugging my amp directly into the wall. No contest. Taking away the current clamp really opened everything up. Sonic improvement was so good that trusting the amp’s own power supply filtration far exceeds the current compromise. But I don’t trust leaving it plugged straight in..lightning, surges, spikes etc.

Question is, what multi’s our there with a power switch do not (Significantly) clamp current? Or do I just keep doing squats until I save enough shekels for a power supply (or house panel protection) that costs more than my amp?

Thanks ahead of time 🙏🏼

System:

Creek Evolution 50A
AlloDigione Player/Transport
Airist Audio R2R dac
Harmon Kardon CD player/transport
Totem Arro speakers
Wirewolrd power cable (amp)

What is a "current clamp?"
What makes you think the Isobar has one?

I recommend running a ZeroSurge 2 outlet into Waber PS-615-HospitalGrade's
I put a 10 ga. PC and a Hospital Grade outlet in my Zero, since I had already installed an Outside in the wall dedicated line.

It was actually your article here that inspired me to try separating components! So let me thank you to begin with (should have mentioned it from the start). 
What I noticed, was that when I didn’t “filter” the power on my amp  it sounded so much better. Even with it plugged into a decent filtered strip by itself (I had tried that too), it was not “quite right”. And I found it fatiguing. But when placed into the wall with Most everything else In the filtered strip, magical, sweet, dynamic, even more detailed, natural, balanced, etc. 

Do you feel the Furman’s filtering will not inhibit tone and clamp the amp? It does seem better than the isobar...

Thanks again!

Sorry...that probably was in no way accurate. Some here have suggested that lower quality power filtering strips can inhibit those moments when an amp needs a quick burst of amperage. Not that the strip doesn’t make it available, but not at the immediacy, or overall designed with the intent to deliver that without gate. My little amp would never require some huge amount that would come close to or exceed what even a cheap strip could deliver, just that the filtering (even with just a filter strip and the amp vs just in the wall) Really does hold back/inhibit the dynamics and overall sound. Wether this is due completely to filtration? My specific amp? Or just cheap filtration? Still wondering.
