Some most subjective opinions about Hi-Fi (and not only) you have ever heard:

• Best speakers I ever heard:
  Audio Artistry Grand Beethoven. (I will never forget the demonstration). That memory lead me to creation of P12 the best of the best projects of my life)
  
• and --- My own P-12 INNERLIGHT- Alnico open baffle.
  
• Worst audio system:
  the award for worst sound at Frankfurt 1995, 1996, 1997 and 1999 goes to full Naim system. Demonstrated by NAIM, so cant blame the set-up or component matching. Everything that I hate about reproduction, in one ugly package.
• Best Audio sound: at Frankfurt 1995, 1996, 1997 and 1999 goes to STAX Omega headphone system.
• Worst demonstration of well regarded audio system in the history: Grande Utopia speakers driven by Carin monos at Warsaw Holiday Inn.
• Best cables regardless of the price:
  IC: Audio Note AN-VZ
  Loudspeaker: Audio Note AN-SPZ in biwiring mode.
• Best budget IC: Goertz Sapphire , Nordost Blue Heaven
   Best small loudspeaker without bass: Sonus Faber Guarnieri Homage.
• Best CD transport: Audiomeca Mephisto with Audio Note AN-Vx analogue cable as digital.
• Best CD player: Tube Technology Fulcrum. Best economy player: Copland 289
  
• Best small signal tube: 6H2P (for 6922 circuits it is a revelation). In every application it is a revelation. Head and shoulders above other, not counting real exotica NOS. MUCH better than the 6H30P so called supertube by mr. Khomenko.
  
• Best Amplifier regardless of price: Audio Note Ongaku. No comments.
  
• Best capacitors for de-coupling:  Audio-Note copper foil paper in oil, and same goes for the tweeter cap. But beware: they tend to BREAK short very easily for no reason at all.
• Best solid state amplifier: TACT Millennium Mk2.
• Best recorded CD for testing of the equipment:  Shirley Horn - "Remembering Miles". Patricia Barber: "Modern Cool"
  
• Best vinyl playback: Clearaudio deck and cartridge.
• Best power tools for woodworking: Kress
• Best DAC chip - Philips TDA1541aS2
