Lifestyle choice, and familiarity with the sound through the whole audio system is important for me.
So personally sound quality and keeping the same CD player, amp and speakers for over two decades has given me high end sound for one major spend, twenty plus years ago.
Consequently its worked out cost effective to have my music in this way. Which is important for me.
A few years ago I was able to have the CD player serviced and upgraded . I found the sound more detailed, but lost something in the delivery. Although it is nice to have HDCD, as I live on a supplemented diet of Grateful dead gigs, and "I'm putting on weight".
I liken this to an old Lp 12 compared to modern Lp12, in sound presentation.
What I appreciate about this concept of audio ownership was I was able to have a very well made product tweaked whilst keeping the main body of the player, ie CDM9 pro transport and the overall build quality of the player the same.
I then purchased the same companies outboad DAC.
Even more detail, but the sound signature of the product is still there, but well fleshed out.
I am also convinced we will continue to extract more information off a CD disk.
I have tried recently to enjoy a music server in an expensive Naim system, whilst it was lovely, it isn't the same sound that I have been able to create at home , in my system .
I'm sure this says more about my preferences on every level, and less about whats best etc.
I didn't like using a tablet either.
However I sometimes look at my shelves of CD'S and say, "I cannot keep purchasing CD's much longer." Well at least until the next live, "Dead gig gets released".
