Wanted to talk about repairs, but the sales person totally ignored me as he was engrossed in a conversation with another customer discussing how bad business is. He didn't think the store would be open much longer. I'm very disappointed as they have had very good reviews.

Feels like being in the 80's when I enter this shop. What's old is new and what's broke is repaired!Hope they have more shits when I go back...

After researching it appeared that Hi-Fi Workshop was one of the only vintage stereo repair/sales places in Tucson. I went in to see what they had for sale, and left with a receiver, turntable, and speakers. Justin was amazing! So patient and helpful. He stopped whatever he was working on as soon as I came in, and spent nearly 45 minutes answering my dumb questions, and showing me what they had in stock. He even rearranged things in the store just to let me hear a system play a record before I ever agreed to buy anything! This is absolutely world class customer service, and I will be back there as often as I can. Thank you, Hi-Fi Workshop!

Hi-Fi Workshop takes customer service to the next level of "phenomenal"!!! My home theater subwoofer needed repair. After calling around, I finally reached John at Hi-Fi Workshop. I liked his style from the start. As such, I took it in for repair. A couple of days later, I received a call from John, informing me that the equipment was beyond repair. He gave me a quote to build one for me, but before doing so, he suggested that I shop around to make sure that I would be getting the best value for my hard earned cash. That impressed me! So, I requested that he build one. When I took it home, I had some questions about my receiver. I called John and he spent almost 40 minutes on the phone with me, assisting me with my questions. My system sounds amazing!!! Hi-Fi Workshop exceeded my expectations and I strongly recommend their services to anyone!!

Took my rare and expensive tube amplifier to them for repair. They diagnosed and fixed it no problem pretty quickly. Highly recommended.

This is really the only comprehensive workshop for stereo and even vintage turntable repair, but since John and Justin are so honest and helpful and also reasonable, I'd recommend simply buying directly from them, if you're looking for quality WORKING second hand audio equipment. Such a gem, this place.

Had my late 70's model Pioneer receiver serviced here and they fixed it quickly and completely. Am very happy with their service. I hope I won't ever need to see them again. But won't hesitate to call them again if the need arises again.

I have an Infinity DSP Switching Amplifier, this was the first Hi-Fi digital amp, they were high end and few were built in the late 70's iirc less than 200. Schematics were never public, neither any service manual. It was working OK until few weeks ago, well almost perfect, it produced a low humming sound when no input was fed but it was hard to hear, but one day I could not get any more power. Knowing the age, design and no schematics I was very skeptical that I could ever have it running again. I live not too far from Tucson so I searched for places that repair High End Audio and after visiting few places one of them told me to go to the Hi-Fi store. John (owner) , took his time and find out the initial problem (no power) and also told me that he found another area that he could repair to get the amp back to "normal".Today I took the amplifier home, price was more than reasonable, I just hooked it into the system and not only works but also the humming that I noticed before the no-power event (btw I never told John about it, he found it) is gone. You can not believe how happy I am, not only this great and unique amp is working again (kind of a collector's piece) but the cost was so minimal. John works in any piece of Hi-Fi.If you ever read this comment John, honestly THANK YOU.

What a great place this is! I didn't have repair work done, but only because Jason helped me figure out what I thought was a dying CD carousel player. He said my symptoms were odd for a player and advised me on doing some more trouble shooting. It wasn't the player, but rather an old patch cord. He spent more than 15 minutes of his valuable time not selling me a CD player, but sending me away happy and VERY impressed with their concern for their customers!
