I agree with adg101 - digital is now as good as the best analog. If you want to spend $1,500 for an upgrade - please boost it to $2,000 and buy a LUMIN D2. I have been streaming a LUMIN D1 for over 4 years. I use Tidal HiFi as my source - once MQA encoding came out I am amazed at the sound quality. I control Tidal on my I pad mini and the available music is overwhelming. My Tidal subscription is $25 per month.
i have just upgraded my CD player to a Yamaha CD S2100 - a great improvement on my Marantz UD 7006. I have a large CD collection and it sounds better. The Yahama has a better DAC and great build quality.
please try streaming! LUMIN has mated the DAC to a computer and done all the hard work for you. MQA digital files will amaze!
Happy listening!
