Imo, the HSU is much better value than the pb1000. The only place imo that svs is better is customer service. They are truly second to none(although RSL is close IME). My problem though, is that their great CS is baked into the premium of their products. Personally, I don’t want to pay for everybody else’s free shipping, and replacement amplifiers. FWIW, I am an svs owner, so don’t think I’m just hating on them, or anybody’s subs that happen to be theirs.
I’m just not their customer anymore. I don’t need the app, and bill of rights etc, and I feel there’s much better performance for the dollar with other companies.
However as a noob, svs is very appealing and may very well be the best option for you.
My window shopping includes Rythmik, PSA(the owner cofounded svs), HSU, monolith, starke, arendal, paradigm and of course RSL.
Just bringing a different perspective here. Truthfully, every sub mentioned will be an upgrade in every way, so you really can’t go wrong.
