The Music Room is the go-to source for the very best in new, used and vintage home audio products. Founded on a shoestring budget in 2010 by Joshua and Melissa Jackson, The Music Room is now the largest online retailer of pre-owned HiFi equipment in the world. Headquartered in beautiful Boulder Colorado, The Music Room is a team of 15 strong (and growing) music lovers – all dedicated to one singular mission: delivering the very best online shopping experience in the audio industry – period. We specialize in well-cared for, previously used gear because that is what we are passionate about. We feel that there is nothing more fulfilling than creating a high-performance system on a budget with carefully selected used components, speakers and cables.

Over the past 7 years, Joshua Jackson and his hard-working staff have shipped over 20,000 pieces of gear to satisfied customers all over the world. That’s 20,000 items tested, cleaned, photographed, listed and shipped. That’s 20,000 audiophiles who have provided valuable feedback about what’s important to them when they buy used gear online. If all that of that feedback could be boiled down to one word that encapsulates our approach to customer service it would be “trust”. We are very proud of the trust that we’ve earned over the years of serving such a vibrant community of audio enthusiasts.

Our inventory changes daily – generally about 100 products per week are listed for sale. These products are acquired primarily from dealers, installers, manufacturers and private collectors. Everything is fully tested, cleaned and function verified before being made available for sale. Our stellar reputation and world-class online feedback ratings have been earned through careful attention to detail throughout the entire process. This includes our “best in class” packaging process and our 45 day satisfaction guaranteed return policy. Unlike a “typical” online used sale, our job doesn’t end with shipment of the product. We have a staff of knowledgeable sales people and technicians who are here to assist our customers after the sale – whether they need technical support, upgrade advice or assistance liquidating the gear they just replaced.

Our doors are open to sellers across the United States that are looking for a fair, risk-free, no-hassle way to liquidate their used gear. With just a few easy steps, a seller can have cash in the bank for their next purchase, and we will do all of the work to find a good home for the previously used gear. Because of our high-volume / low-margin approach, we are able to pay a fair rate for used gear – well above what most folks would consider to be a “wholesale” price. Logistics is our specialty, and we can generally handle 100% of the packaging and shipping regardless of your location.
