Hardware or source materail

Hello –

The following is for context.

I am an old guy. I grew up in the days a Mac 225, AR3a, EPI, Phase Linear. I have only recently stopped working full time so I bought the following for my small office listening area, about 12x12.

Debut Carbon/Ortofon Blue

CA AXR100

Denon 600NE

KEF LS50

B&W 8” 300 watt Sub (sealed)

I mostly listen to orchestral, Steely Dan, Miles, Brubeck, Krall, Botti – you get the idea. I also am season holder for LA Phil and Hollywood Bowl so I know what “real” music sounds like.

My little system may not be to everyone’s taste but I find it fills my little space well.

Here is the quandary:

Like most, I am always thinking about the next “upgrade” for improved fidelity. Don’t need loud or to fill big space. However, I just purchased a half-speed (45 RPM) Brubeck and was absolutely astonished at the dynamic range and sound quality. I believe that what it is telling me is that with the right input the hardware I have is maximized.

Obviously, a $7K amp and equally expensive supporting components would be even better. But how much better? Is the investment in better source material a better use of funds? After all, that will always be available if the hardware is improved. You can buy a lot of $60-150 vinyl records (or CDs made from masters) for the 15 to $20K hardware cost.
