My System's Weakest Link - What Say You...

First off, McIntosh bashers need not respond.  The synergy of this system is outstanding.  

I think I have my system pretty well fleshed out now, and love what it is doing for me.  But, I have my eye on my weak link.  I have a few thoughts, but I'm Interested in objective, and somewhat random comments from some insightful folks here.

My Habits:  Love listening to vinyl most of all. Don't know exactly but have over 3000 LP, I think, and keep getting more.  Obviously do lots of streaming too via Tidal > Roon. Also on thousands of CDs of varying quality.

My Room: Open main floor Floor plan to the kitchen and formal dining room.  Open space has 9 foot ceilings, with fabric chairs and carpeting.  No need for any room enhancement identified.  Still sounds great.  Lucked out on that one.

Anyway, where is what I have:

• (1) McIntosh MT5 Turntable
• (2) Sumiko Palos Santos Cartridge
• (3) McIntosh MP1100 Phono PreAmp
• (4) McIntosh C1100 2-piece PreAmp
• (5) McIntosh D1100 DAC
• (6) McIntosh MCT 500 CD/SACD Transport
• (7) McIntosh MVP 901 A/V Player
• (8) McIntosh MC2152 70th Anniversary Amp
• (9) McIntosh MPC1500 Power Controller
• (10) Sonus Faber Lillium Speakers
• (11) Roon Nucleus
• (12) Sonore Signature Rendu SE w/ Optical Feed
• (13) All Connected via Clarus Crimson interconnects, power cables and Balanced Cables
• (14) Will avoid the details on isolation, AC outlets, etc. for now.

Choose a number, product or idea.  Have fun with this one.

"Long haired, freaky people, need not apply" or dismiss my enjoyment of McIntosh.  [btw - anyone remember that song quote?]
