Is my Cal Audio Sigma II too old?

It seems like I have had my Cal Audio Sigma II DACs for 12 years or more. Is this too old? Have DACs come that much further since it was made? I always liked the warmth of this tube based DAC and currently have a Telefunken smooth plate in it and still enjoy the sound. Regardless of its age, it still sounds less harsh than the DAC built into the Sonos Connect I use for my digital listening. This is connected to a NAS drive with redbook cd flac files. I don’t really have the 2 grand at the moment for a Benchmark 3 or a Mytek Brooklyn but I’m not sure I need or want all that additional functionality. I just use it to decode the digital signal. Would a more modest DAC outshine this older unit?

The rest of the system consists of a McIntosh C712 preamp, McIntosh MC2102 tubed power amp and Magnepan 1.7i speakers.

The dac chip in the Cal Audio Sigma II is an old Cirrus Logic Delta Sigma, in my opinion not worth hanging on to.
If you play pcm "redbook cd flac files" as you said, then you should go with a R2R Multibit type dac, look at the Schiit Yaggdrasil.

Thanks for the input.  I realize the C712 is a weak link but I am someone who cannot live without tone controls, in this case the loudness knob.  I have been considering a C46 due to the 8 band EQ but I'm not sure how much of an upgrade it would be.  The C712 also has some sentimental value because I am the original owner since 1993 and it was my first decent piece of gear.

Note note to self: Count the number of posts someone asked for a suggestion for upgrading xxxx (fill in the blank with any audio gear) and georgehifi did not respond by including a link to Schiit website or not recommend one of their products.
Sorry just could not resist...Please carry on.

Schitt has already been in the back of my mind and whilst there may be shills on here, I'm actually thinking the Schitt Bifrost MultiDac may suit my current budget.

Yes too old. It might even benefit from a recap. Save up until you have the 2k you need and do it right. Dont compromise and buy sh-t.
