All audios journeys are tied to dollars and rooms
My room is huge volumetrically speaking: ~ 20 x 40 x 12ft peak in open beam ceiling, front wall is 70% glass floor to ceiling, while the back wall is actually 3 sided all glass from floor to ceiling, plus up/down stairwell in the middle of one long wall, all of which add up to needing more umph to load this room.
Approximately 3-4 years ago I purchased Emerald Physics KCIIs knowing they would be out of their depth, BUT, they came with a BOM (bass management) and I already had 2 @ 12" SVS powered subs, whose volume controls are the WORST, driving the amps to play WAY too loud when barely cracked, and was hoping the BOM would solve it, but no bueno. I even have an pair of EVS attenuators, which I tried on the SVS sub inputs running their built in VC at full volume, but adjusting the attenuators starting low, again no bueno.
Various Class D amps included Emerald Physics 100.2 SE monos with upgraded fuses, but they didn’t do it for me, followed by Audio Alchemy DPA-1, followed by PS Audio M700s, which did a very good job, and I would have kept them longer, BUT, they are stock, AND, at that time (a year ago?) Ric introduced the EVS 1200, which was only a couple hundred dollars more then what I knew I could sell the M700s for. For me that was a no brainer, whether I need all that power or not, it is a hot rod of Rics tweaking abilities. And, I totally agree that bigger power supplies can be HUGE on smaller wattage amps
The 1200 combined with the 3.4s is quite magical on quality recordings, but lower bass is still missing IN THIS ROOM. I have been impatiently waiting for EP 2.8s which are 97db when single amped. The speakers are arranged in D’Apolito each with 2 @ 15" carbon fiber woofers in addition to the same 12" carbon fiber concentric driver/ polyester tweeter as in my 3.4s. Once they’re in the system, I could evaluate your Purifi amp, and am still in line for the LSA Voyager GaN amp MSRP $3000 for 200/400wpc: I am told it has a bigger PS than needed for the same reasons Ric mentioned. It is possible that the EVS 1200 could eventually be used for the bass and one of these amps for the mids/tweeters (be still my beating heart). In this case possible likely means probable
