Allo all, finally got it working so I thought id add a few of my own, whilst not up to the hi-fi standard and cost of many posted above it sounds pretty good to my ears, New forum user but have had a financially ruinous appreciation for that "perfect" sound since the late 80's after saving up my minuscule pay from first job to buy a walkman DC-2 paired with Koss-Porta pro headphones, That's how it started.....pics below show how its going 31years later
2020 iMac/iPad Pro with 500gb ish Flac files running Roon/Tidal hifi - Cambridge Audio CXN V2 - KRK 10s sub - KRK G4 Rocket 7, Audioquest Cinnamon usb cables, Audioquest Pearl Ethernet cables to iMac/CXN V2, balanced Neutrik XLR cables to sub/speakers with isoacoustic 155 speaker stands and isoacoustic 200 subwoofer stands. Quite a few GIK Acoustics room treatment panels, 4 of Tri corner bass traps (corners of front wall), 2 of 244 bass traps with flex range limiter (front wall), 2 of 4A Alpha pro diffusers (front/rear wall), 2 of 2A alpha pro diffusers (side walls), 7 of 242 acoustic panels (2 @ first reflection, 5 still to fit to ceiling), 2 of Monster bass traps with flex range (rear wall). You'd think that'd be enough in a 3.3m x 4.2 m room right?.....Nah - not quite........I have a spike at 70khz and 100-125khz (I love the visceral thump of my sub) so I'm also buying 2 monster bass traps with flex range to sit on floor/against front wall behind desk and 2 of scopus tuned membrane T70/T100 bass traps for far rear corner.
It sounds pretty bloody good as it is and an unimaginable difference compared to the non treated room beforehand but I do like my electronic music at a healthy volume so needs must, waiting on a floor to get laid but covid restrictions have put that on the back burner for the foreseeable future so there's nothing left to do apart from sit down and enjoy the music.
Fortunately sitting down is one of the things im rather good at due to secondary progressive multiple sclerosis and a good sounding room to sit in is well worth the effort to treat, Ive spent far more on the room acoustics than my hifi system and from my perspective, currently sat on my arse listening to what surprises roon radio throws at me it is fantastic value.
