What to add or change for my system?

Not to start a heated debate, but what about changing the fuses in the Plinius?  Pretty easy as all fuses are accessible from the back of the unit.  I've read pros and cons on this, as I'm sure all of you have too?

You should check out the thread on the Synergistic Research quantum black fuses. They seem to get tons of raves. 

You have a very nice system and the next upgrade is going to be expensive. Separate components with mono-block amps is the next level and if it was me the mono-blocks would be tube amps. Keep the integraded amp in case you need a spare when equipment goes out of service. The next level will provide significant improvements.

Thanks russ69, that's what I was afraid of. :)

I did add Synergistic research Black fuses to the Plinius integrated.  My daughter is staying with us and she is my help to make sure I'm not hearing improvement when it's not really there.  She has no dog in the hunt.  She's been listening to my system with me for about two months now.  She helped with the Clear day speaker cables.  As soon as I turned on the Plinius with new fuses, she looked at me and said "WOW!"  I heard the difference too, but usually doubt myself.  She is also very sure there is a significant difference.  I feel the money for the fuses was very well spent.  

Bryston told me not to bother upgrading the fuse in the BDP-1 because there are no fuses in the signal path, and the fuse in the OPPO is soldered to the board.  The DAC has no fuse, so I guess I'm done until I get the urge for those mono-blocks.

Thanks everyone!!!
