Just wanted to give a thumbs up to the Nordost System Solution set-up and tuning discs. Unlike many other such discs that I have tried, the Nordost product has allowed me to fine tune my speakers to the point where they disappear completely, regardless of whether the lights are on or off. I’m really pleased with the results and highly recommend these discs. I have no relationship with the company, just a very satisfied customer.
Found it on eBay uk from Analogue Seduction, just listening to the music tracks and enjoying rather than any set up or tuning up this evening… disc 1 track 28 your colour sung by calypso has blown me away and I can’t find her on google
