New additions to my 10 year old system includes Luxman amp, Audio Research SE upgrade to REF 150, Linear Tube Audio headphone amp and Focal Utopia headphones and Audioquest Niagara 5000 power conditioner
SME turntable has new Clearaudio Stradivari cartridge as well.
One can never know unless being there, but those speakers appear space constricted.
I would push them out into the room more, and away from the side walls, a wee bit closer together. Looks like a hot room with lots of reflective surface?
Rack in the middle with speakers so close looks like a deal breaker, sonic wise. Just observation- If it sounds great to YOU, you're done! Maybe one more G1 on the other side, 3 more for ultimo, audio nirvana.
