Scalable and Fun: Tailor your sound experience by swapping the stock NE5532 op-amps. V3 is compatible with a variety of 8-pin dual op-amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4559, LM4562, LME49720HA, etc
Note: The "Pre-out" level is NOT controlled by the volume control as the V3 is not an integrated amplifier, so the sound is NOT adjustable when you are connected to the "Pre-out"
