The Fosi ZA3 monobloc amps ($300 for 2) sure opened my eyes. I have some nose bleed expensive equipment, a system in every room, and the ZA3s (even better with Sparkos 3602 opamp upgrades) are just wonderful.
$300 amps, a Pure Audio Lotus5 DAC, $850 used, a pair of Dahlquist DQM905 speakers, $60, and this is one terrific sounding system.
Always looking for something better. So, I have a system with Harbeth 30.2 ($7000) speakers, a Line Magnetic 845ia integrated amp ($4900) a Denon DP45f turntable ($300 used) with a $169 Goldring E3 cartridge. Sounded great. Looked great.
OK, so I was willing to pay a bit for improved sound quality. Bought a Hana ML mc cartridge. ($1200) Couldn't adjust the tonearm height, so it didn't fit. Didn't want to return the cart, so I bought a Technics 1210G, fitted the Hana.
Does it sound better than the $300 Denon and $169 Goldring cartridge? Maybe a little, not sure.
I wish I had left good enough alone!
As to the Fosi amps, what an eye opener. I could have saved a boatload of money on the amps and put all that money in speakers, or DAC, etc.
