Melbourne Audio Club preamp comparison night equipment
|
For the preamp comparison my 12AX7 Tube Preamp and OP Amp Preamp were used. My Gainclone monoblocks were used for the power amps. The speakers in the other image were built by a club member also. An A/B switch was used to switch from one preamp to the other under a blind test situation. This allowed a quick comparison between the two very different preamps. Though the chip preamp was voted the better (60/40) many still expressed their preference for the valve preamp.
