Hello! For most of my life, I’ve been involved in the medical imaging (think x-ray, CT, MRI, etc.) world…first as a user/operator, now in sales. One thing I learned from being in those environments is that Tripp-Lite makes a damn fine, no non-sense product; a lot of imaging systems came with their stuff to protect computer consoles, servers, etc.
I’ve been using a Tripp-Lite LCR2400 for the past 7 years and have been very happy with it. It provides voltage regulation, monitoring and line protection…nothing more, nothing less. I haven’t noticed any sound difference between having it in my system versus direct into the outlets (a good thing!), but feel much better knowing it’s there protection-wise. It gets great reviews, is pretty much bullet-proof and just plain does what it’s supposed to. The other thing going for it is it’s very cost effective…I bought mine from Office Depot for under $400.
Only negative for me is that this unit is known to have a very faint buzz to it…in a totally quiet room, you can barely hear it, but it is there. Obviously, once the music plays, one doesn’t hear it.
If I ever get the itch, I may get a true-audiophile unit from Shunyata, PS Audio, AudioQuest, etc…but, really, the Tripp-Lite meets my needs perfectly.
