I started with Kenwood, Realistic, Yamaha. Onkyo, and Marantz ....with cheap Bose or Advent speakers.
Then I graduated to a Luxman 505 UxII and some Epos Elan speakers. The sound was not all that much superior.
I then decluttered my room and treated with GIK products.
Quite a vast change and likely the biggest improvement.
However I since have went tube gear with McIntosh C2500 and MC75 monoblocks---mated to Sonus Faber Oly 1s. I also changed my streaming products from a Node 2i to a sonore rendu, Small Green Machine Roon device and a Mytek DAC+.
Nearly everything has made an improvement. But the Luxman I still have as a backup. I will say I FAR prefer my McGear to the Luxman.
I checked out that guy’s "store". Yeah he states buyers need to convince him to sell to them. Yeah right---I did not see one thing in his place I’d want. I checked out his super room vid too. Well I’ll just say I don’t care for this Jay either that he says states his system is the best ever---much prefer the Jay that used to work with Adrian and Villup.
So far I seem to be the only thumbs down on his most recent you tubes.
LIkely wont be visiting his channel in the future,
Im not a huge fan of dealman or ask paul or darko either but these guys are saints compared to this dude, jay labs, the SR magic props Denby (whatever his nam eis--who cares) guy, and the audio circle guy (ASR-Amir?) that hates just about everything. Frankly, IMO, we need more Audiofiliac and Gene Della Sala types.
