About Seven Grand Service
Seven Grand Service operates as a stereo repair specialist in Redford Township, Michigan, earning a 4.8-star rating across 28 verified reviews. The business handles repairs for vintage and contemporary audio equipment including receivers, boomboxes, and cassette players. Technicians at this facility have serviced brands such as JVC, Sansui, Sony, and Pioneer, addressing issues ranging from stuck cassette mechanisms to channel failures in stereo receivers. The shop maintains Monday through Friday hours from 9:30 AM to 5 PM, serving customers throughout the Redford Township area and surrounding Detroit suburbs.
What distinguishes Seven Grand Service from other repair shops is their commitment to honest diagnostics and reasonable pricing. Multiple reviewers note that the technicians identified issues other shops either missed or misdiagnosed, with one customer recalling that another shop recommended scrapping a vintage Sansui receiver that Seven Grand successfully repaired. The team contacts customers before proceeding with repairs, explaining the specific problem and providing cost estimates upfront. This transparent approach has earned praise from customers who appreciate avoiding unnecessary expensive repairs.
Customer reviews highlight specific technicians and repair scenarios that demonstrate the shop's capabilities. One reviewer described working with Harry to resolve a stuck cassette in a JVC Boombox, noting the efficient turnaround and quality service. Another customer recounted bringing in a vintage 1969 Sansui 2000 receiver that other shops deemed beyond repair, only to have Seven Grand restore it at a reasonable cost. A third review mentioned a technician named Desh quickly fixing an AC unit, though most reviews focus on audio equipment repairs. The shop has also been praised for declining repairs when equipment is actually functioning properly, as in the case of a Pioneer Receiver where a faulty connector cable was the real issue.
