Shop has a great selection of refurbished phones if you are not interested in paying $1200 for a brand new one but still want a good phone with many of the newest features. Sam is also helpful in understanding the differences between phone models and suggesting which ones might be the best fit for my needs.

I have newer - u-turn audio - turn table that wasn't producing sound out of the left speaker. Not usually the kind of thing he works on, but Dr. Dan agreed to check it out anyway. I spent about an hour with him in his shop, surrounded by pugs, chopping it up sharing stories, while he troubleshooted the issue. After a few tests, he figured out what was happening, recommended I buy a $20 preamp to fix it, then sent me on my way with a handshake and a smile. It was quite the enjoyable experience. You can tell he cares about what he does, that he takes pride in his work, and is extremely knowledgeable when it comes to vintage audio equipment. *He's also a man that enjoys a good story, so if you have one, come prepared to share.* I personally value vinyl. It's a beautiful analogue tech that produces sound using magnets and emf's translated from a needle cruising on plastic. It's crazy to me that someone had the idea for it, let alone that it actually works. Yet it remains. Not for the nostalgia or efficiency; but for the warmth of the sound, for the collectibility and sense of ownership, for the love of music. I was looking for someone who held a similar sentiment. You wouldn't want someone who hates cars to be your mechanic. I decided to call Dr. Dan after reading some reviews, in which pretty much everyone suggests he the best. To that point, all I can say is, they were all right.

I post this with the caveat that I don't know if Dan is a good technician or not. I have not been…read moreable to power up the system yet. This review is limited to customer service. I have a McIntosh C28 preamp and a McIntosh MC 2105 amp. Between working overseas and moving, neither had been powered up for some time and had been on a shelf in the garage. I wanted to set them up again, but before I powered them up, I wanted them cleaned and checked out. I contacted Dan and got an estimate, then dropped off the amps on Dec 31st for what was promised to be a two-week job. On January 14, he called me to tell me they weren't done. He texted me some photos of what he was doing and said it would be another week or two. After that, I heard nothing. I texted for updates but received no responses in return. On Feb 20, I texted again and said we would be in Denver the next day and asked if they were ready as I would be out of the state after that. He said he would only be there in the morning during the time I would be at a powerlifting meet. I asked for confirmation that they were ready and I could pick them up a couple of times after that. Finally, he responded when I said I was out of the country, but my wife would be in Denver on March 21st. I asked for the price and confirmation of the address. There was no response. I asked twice more before I got those, and he specified cash or check only. When my wife got there, he called me in Ireland and started berating me, telling me he was so popular, everybody loved him, and I was disrespecting him. I was quite surprised, and I asked him how. He said I texted him instead of calling. (For the record, I have hearing loss from thirty years in the Marines, and I prefer texting, especially when I need specific like costs or addresses. Also, at least twice, I called and left messages which were never returned.) He then actually yelled at me over the phone, saying my amps were too big and took up too much time in his shop. There was more, and I bit my tongue as I just wanted my amp. When my wife went to pay with a check, he demanded cash. She contacted me, and I sent him back the text where he said checks. My wife picked them up, but he did not put the amp back in the case. When I returned, I tried to do it myself, but so far, I've failed. I called him but got an answering machine. He did call me back, but to berate me again, saying he was angry on the 21st and he was still angry. Once again, I bit my tongue as I wanted my amp working. He told me he didn't put it back like I brought it because it had been difficult to take out in the first place. He told me to push the releases on the front and find the clasps on the back, and when I told him I couldn't see anything, he said find a YouTube video. Then there was more beratement, most along the lines that he doesn't have time to respond to texts, he is too popular and everyone loves him, he is anal about his work, I don't know anything about amps (true, which is why I hired him), how no other service provider uses text messages, he complained that he didn't know my wife (whom he met along with our seven-year-old identical twins when I dropped off the amps), and how it's all my fault because I wasn't calling him all the time. Then, when he repeated that he was angry at me, I said it was mutual. At that point, we had a minute or two of back and forth until I said this was getting us nowhere and hung up. As I noted above, it is possible that Dan is a wizard with the tech. But I received no invoice to know what was done, the amps were not cleaned, and as far as I know, only three components were exchanged on the preamp. But most of all, I have never in my life been treated like that by a vendor of any kind. I have never been scolded like a five-year-old child. I can not recommend "Doctor" Dan for any kind of service.
