Having spoken to Both Mark & David I decided to upgrade my Cary pre amp,Lector 4 box DAC& CD transport as I really wanted the convenience of being able to listen to a wide variety of music not just what I had in my collection.Having firstly upgraded my Cary Pre amp to the W4S STP WITH STAGE 2 upgrade as Mark said is was a cracker plus ideal to use with my existing SX1000R mono’s which I loved. First impressions was it was in a completely different league to the Cary both in terms of detail and overall sounding more realistic with greater seperation. Next came the SOtM Ultra bundle along with the Aqua La Scala DAC, firstly love the fact I can use my Ipad to access my playlists using the SOtM which offers not only incredible convenience but more importantly I’m now listening to music I’ve never heard of because of the superb Tidal App which is a joy to use . Next the La Scala which without mixing my words is simply mind blowing in every aspect from seperation which is just stunning, to the overall sound which is as if a filter has been removed from the music as it’s been allowed to breath naturally- although it does need lots of burn in which I was advised , everything just sounds breathtaking in its presentation. It’s always a real pleasure dealing with Elite Audio as they know exactly what they are talking about & just as important to me how to construct synergy with my existing system so it works as it’s best. Highly recommended
