Next upgrade options

Hello all,

So, I have invested quite a bit and reached this audio chain (listed below). I also upgraded power cables, interconnects and speaker cables. So far, I am pretty happy and found noticeable difference with every step of the way.

I am seeking advise/opinion from fellow audiophiles on what can be the next upgrade.. I am seeking more body, fullness and perhaps a little more analog sound.

Option 1 - speakers (not sure what . I love bookshelf)

Option 2 - separates on Amp ( perhaps Gryphon or M10x with a pre-amp)

Chain -

Aurender N20 --> DCS Rossini DAC + master Clock --> Luxman 509z --> b&W 805D4 + dual Rel s510

I love and hate this hobby ..
