best preamps

Unlimited budget means a call to CAT, MBL, or dartZeel... they can hit $100k if you want to burn some cash

Unlimited budget could mean a call to Naim Statement gears, Boulder, Tidal, MBL, Soulution, CH Precision, Burmester, D’Agostino Momentum series, etc. They can hit close close to a million dollars for the shoe setup and system.

Refurb Audible Illusions L3A linestage or Modulus (w/ phono stage). Tubes. 

I can not recommend Best preamps because that company went out of business years before I could afford one.    Sometimes you can find a used one on Ebay for a cheap and may be worth a go to find out for yourself first hand.   Why a Best preamp?  There are so many good ones today, why bother?

I say PS Audio Signature PreAmp, it’s $6000.00 but worth it. It works great even with high efficiency speakers. Mine are 97db efficient and there are several YouTube videos about the making and the sound.
