Paul, the Furman reference series (as well as some of the similar Audioquest Niagara’s ) stores energy to deliver more current than available from the wall for short times for increased transient response. I was putting together a small system with a Hegel H190 and bought a used Furman Reference 15. It does store some energy, though not nearly as much as my Niagara 7000 in my main system , but the very old Furman did help most aspects of the Hegel integrated. Cleaner power can sound less exciting or lower in volume, but adding back some gain fixes it and reveals a more precise presentation with added micro and macro dynamics.
Power conditioner some say yes and some say no.
Depending on who I ask a power transformer conditioner can have a good effect on the sound while others claim they inhibit the dynamics of an amp. I don’t have serious power problems as far as I know but I enjoy my sound most of the time. I currently use a Hydra 6 for my entire system except for my amp where I use a Hydra 2. Would it make sense to invest thousands on a power transformer conditioner or would my Hydras be enough by isolating the components from each other. I was waiting for a Keces IQRP 3600 to try but the dealer I was to get it from died from Covid-19 before arranging my Keces to be shipped. I am out $4000 and am not so fast to drop another $4000 on the Keces. Perhaps in the future if it makes sense. I find that not many use transformer conditioners due to the dynamics limitations of the amp. Any help would be appreciated.
