Service Policy Changes as of 09.08.2020:

Service Queue Reservations suspended until at least 11.30.2020

A new process has been developed so we can serve you more efficiently in conjunction with our recent product and showroom expansion and reduce in-lab service backlog. This allowed us to eliminate timely equipment walk in and drop off.

IMPORTANT: Please enter ALL REQUIRED information for your

component(s) / speaker(s) in the "Contact Us" form provided above:

Phone Number
Email Address

Problem(s) you are experiencing?

Once received we'll send you a confirmation of your request; you'll receive an email 1-2 weeks prior to your appointment notifying you to drop off your equipment.​

Vintage Audio Service Customers

This is subject to change; sorry for any inconvenience.

passive speaker and turntable services will still be accepted; for details and/or questions contact us in the form below.
