If you own a Sony TA-E9000ES processor/pre-amp, then you need the latest version 2.01 software. My kit arrived today from USA, installed and working perfectly, certainly improved the sound, especially with 2 channel digital sources. Adds 'virtual' EX 6.1 modes etc. You have to pay for this upgrade, as it includes a new 'simple' remote with the kit. Price is about $100 US + delivery.
