The Bolder modded SB3 for me.
I could argue the old Magnavox amp, but my JVC EX-A1 backup does a credible job.
I could argue the DIY Visaton speakers, but I could build other speakers I am sure I could live with.
I could argue the Felicia I have, but dirty power wouldn't end my love of music.
I could argue the dedicated PC I have created for use with my audio system, but the truth is that I could always just load s/w on my work PC, and use an outboard drive.
In the end, it is the combination of fidelity, convenience, and simplicity (I use a single source system, so I was able to sell off pre, dac and source when I converted to the SB3).
