Howdy. I have a JMT built CMOY that uses the OPA2134PA with a single 9v battery. I would like to boost the voltage that I give it for better sound. Since I recently bought a META42 built by fyleow that came with an Elpac 24v DC power supply, I would like to replace the battery power and use the power supply for both amps.
However, I am not sure if this power supply would be too much juice for my CMOY. Can you give me some advice?
Also, concerning the META42....fyleow was forward thinking enough to socketize the OPA637 for this amp so I could roll the chips. I wanted to purchase either the AD843, AD845 or AD8610 to roll out to get a 'snappier' sound than the excessively laidback OPA637, but I was also concerned with giving these excessive voltage. Tangent's opamp roundup gives lots of info about how much is required to get good sound, but not on how much is too much. Can you help me with this as well?
