A life sentence!!!

I would have to say my speakers. DALI Mentor 6s I’ve had for several years now.  I’ve changed out/upgraded sources, preamps, amps and cables over the years but have never really been tempted to change out the speakers. I bought them after hearing the Epicon 6s and I believe I’d have to spend far more than I want to in order to gain a significant improvement. I have DALI speakers in my office system (Menuet SEs) and my tv system (Opticon), so I’m pretty locked in to the DALI house sound. 

My accuphase e470 with dac card and phono section. It’s sublime. 

My music.

Conrad Johnson Premier 17 LS pre amp ...my sweetie.

For me, it would be everything I own! It performs as 1 seamless entity.
