Upgrades

I have redesigned the input circuit for a noticeable sonic improvement. This upgrade is standard in all D-Sonic models manufactured after 5/5/2017. The entire amplifier lineup has now become the M3a series from the original M3 designation.

I am offering a retrofit to existing customers who have Pascal technology. If you are not sure about this, call with or send me the serial number. The upgraded amplifiers are then given an M3a serial number prefix to certify the upgrade.

SHIPPING:

I will send you a prepaid UPS label pre-addressed and fully insured . Amplifier can then be dropped off at any UPS outlet. You must use original factory packaging including clear plastic sleeve. If you do not have the factory packaging, have UPS pack and insure it at their facility also using a plastic sleeve. This is important to prevent scuffing the faceplate.

You can also ship your unit back to D-Sonic yourself as long as you meet the requirements listed above and no signature is required. Insure for a value that will cover any damage or loss. UPS is preferred. FEDEX will not allow deliveries without signature even when they say they will and will no longer allow me to change this status online.

You will need to ship your amplifier to:
