Harman Kardon Citation 14 Tuner - I can’t tell you how pleased I am since Bill Ersoy at Cherish44 has made a real Harman Kardon Citation 14 from two eBay buys... Sounds just wonderful... Even better than my antique Citation 111... It looks great... And the sound is so crisp and clean!

Working with him over the weeks took time to make it, but it was a pleasure... I felt like I was looking over his shoulder...  Waiting and working with him was more than well worth it...

This is truly an electronic repair group that takes real care of all details... Real precision was what I wanted and what I have received. - F. L., DC, Dec, 2017


Fisher Studio Standard RS-2010 - 5 star, nobody like Cherish44!  If you need vintage stereo service, you found them. - J.A., OH, December, 2017


Marantz 2230 - I purchased our Marantz 2230 in 1972 at the audio/photo store on the US Army Base where I was stationed in West Germany. Over the years the receiver developed a number of issues and lost its ability to create the great sound it was once known for. With so many years having passed since these classic receivers were made, it is extremely difficult to find anyone to repair, much less restore, these receivers to their former glory.

Bill Ersoy of Cherish44 is the rare exception. What Bill did for our Marantz was really a restoration rather than a repair. We are pleased to once again be enjoying the Marantz. The result exceeded our expectations. I would not hesitate to recommend Bill. He will evaluate your receiver and give an honest appraisal both as to the possibilities and cost of restoration. -

Telefunken TR-600 - I have known Bill for a few years now and consider him a good friend. He has impeccably restored a few units for me already.

I've recently sent Bill a real challenge. I acquired a beautiful and rare Telefunken TR-600 Receiver with some issues years back and always wanted to get it restored but couldn't find a tech that I completely trusted to take on the job. Well, all I can say is that Bill has somehow done it again. I was amazed when I saw the unit when Bill was done, and was floored when I hooked the Large Advents to it. The Telefunken came back to life!!

The receiver is now extremely musical and clear. I asked Bill to work on the tuner section for me and could not believe the improvement in separation, signal strength, and crispness of the FM stations. He also somehow brought both dead VU meters back to life (he still won't tell me how he did it LoL).

Bills attention to detail, knowledge, experience and excellent communication are his biggest assets. He was there for me during the entire restoration, giving me options and honest advice on how to proceed. Just like my auto mechanic with whom I have become friends with over the years, because he is honest, fair, and genuinely cares about my children who are riding in the car, I trust Bill with my other "Children" 🙂

Thanks Again Bill for another amazing job, and I look forward to our next project together. - C.T., Ontario, Canada, September, 2017



Marantz Model 2600 Receiver -  Hello Bill,  I could not be more pleased with the work performed on my Marantz 2600. What a difference now that all the gremlins are gone.

The original assessment of the unit was spot on. The conversations with Cherrish44 on the ongoing progress and solutions were unusual in today's environment of quick fixes. I learned a LOT about the history of Marantz receivers and why/how things were done in the 70's.

When looking for someone to work on the unit I got a lot of I can do that for $600 or $1500. You said hard to tell without looking and going over the unit from end to end. That was sure the right answer and I am SURE I made the right decision.

I find it hard to turn it off as the butter smooth sound of a Marantz 2600 (600 watts) fills the house (and the neighborhood).  The BEAST is back playing great tunes again. If anyone is looking for a very professional restoration with incredible results Cherrish44 is the place.  Thanks for everything. - M.H., MD, September, 2017

Pioneer Model 950 Receiver - I would like to take some time to recommend Bill and Cherish44 as your ultimate and final choice for quality and professional audio repair and upgrade. Bill is such a nice guy to meet and work with, a man dedicated to his work and the resulting performance from equipment he has worked on is stunning.
Based on the work he did on my SX-950 he now has my Quad 405-2 amplifier, Quad 34 pre-amp, Marantz 2325 receiver and a Panasonic RF-4900 professional multi-band receiver. He will shortly also get my McIntosh MR-78.
Look no further, Bill and Cherish44 are the ultimate resource. - I.J.H., MI, July, 2017

Marantz Model 150 Tuner - I sent Bill my Marantz 150 for service. After reviewing the unit, Bill contacted me to discuss what he had found and to put together a plan for refurbishing the unit. Bill also took the time to explain to me the type of antenna that would work best with the unit.  After receiving the unit back and purchasing the suggested antenna the sound and stereo separation is nothing short of amazing. I have Sirrus XM satellite in the house and the stereo separation of the 150 is better than the satellite. Bill now has my Marantz 250 and will be getting my Marantz 3300 for service. What I think is unique about Bill is the communication, customer service, and time he will take to discuss and explain the plan he has for your unit. Bottom line...If you have a vintage stereo unit, or any unit for that matter, Bill is the ONLY one you want working on your gear. - E.G., SC, July, 2017

Sansui 5000X Receiver - Bill Ersoy of Cherish44 repaired our Sansui 5000X receiver. While the repair of the Sansui was quite efficient, the process from start to finish was lengthy due to the demand for Cherish44’s work. This latter consideration speaks to the confidence to do quality work that Cherish44’s clients have in the business. In the end, the result is worth the wait.

Once underway, the work proceeded smoothly with good communication from Bill. General cleaning, various alignments and several parts replaced summarize the undertaking. Following were various tests of the unit to be certain that the Sansui was operating at its peak. Bill was meticulous in his approach and implementation, even considering the type of speakers and speaker wire to be used with the Sansui.

Bill’s concern is with the sound produced by the equipment, not just with repairing its components. In our case, the final result was a vintage receiver refurbished to optimum performance. ​-  J.A. /  S.A.,  MI, June 2017

… in every instance of each audio project submitted to Cherish44, Mr. Ersoy has exceeded our expectations, and in a manner fair to all principles involved. From our requests for conformance to purchased component specifications reporting to improved redesign of existing audio component circuitry Mr. Ersoy has become a valued partner in our ability to better serve our customers... - A.J.B., OH

... I am an audiophile and a collector of classic vintage audio equipment. My extensive collection includes stereo receivers, power amplifiers, preamplifiers, turntables, cassette decks, tuners, and loudspeakers. I select the units I acquire very carefully, evaluate my units thoroughly, and proceed with service activities on these units with the best possible service alternative available near or far, that is known to me. Cherish44 is the service provider for my entire Marantz collection. Here is why.

Cherish44 under the management of Bill Ersoy has the ability not only to service my units, but also the exceptional skill to improve them if and as needed in such a way so that

- The original sound color of my units which I enjoy so much is retained
  - Design and/or assembly related weaknesses of my units are eliminated
  - My units are taken performance-wise well beyond factory specifications

Through my observations and conversations with Bill Ersoy I understand that strict and continuous supplier management, research and development management, operations management, and last but not least quality management are key elements in Cherish44’s most successful approach to my classic audio units. In my opinion it is this organized and combined managerial approach which enables Cherish44 to produce consistently highest possible results in this field.

In my opinion advanced technical knowledge and excellence in management are not the only requirements for successful customer service. A most important ingredient is honesty combined with truthful consultation. Over time I made the experience again and again that the information I was provided with by Cherish44 on my units was nothing but the truth itself... - D.V., Ontario, Canada

...I am a customer of Cherish44, I like music, and I am the owner of a pair of well-known Klipsch P39F loudspeakers. I am a collector of high end vintage audio equipment and I got interested in the Sansui AU X1 amplifier. It’s a hard to find amplifier and one of Sansui’s best. Finally I was fortunate to acquire one.

After a while, my AU X1 stopped working. I took it to a local repair service provider and asked for help. The unit was inspected and I was informed that they were not willing to service it due to the complexity of the unit, amount of damage, and lack of test equipment. Having received this let down, I started a search on the internet for another service provider.

I found out that the unit was one of the most difficult amplifiers to service. Finally I was able to locate a service provider in Long Island, NY which gave me hope, as they were known for their competency in servicing vintage units manufactured by Sansui. With that, I shipped my unit to Long Island, NY. Around 3 months later upon my follow up, I learned that no progress was made in servicing my unit. They asked for additional time, which I gave. Three more months passed and not having heard back, I contacted them once again. This time I was informed that the damage in my unit was beyond repair. They suggested taking apart the unit and selling it for parts on the aftermarket. I was not willing to accept this and asked them to wait until further notice.

Once again I started to search for another service provider. This is when I found Cherish44. I contacted them and talked to their manager Bill Ersoy. He was welcoming and invited me to send in my AU X1 for an initial inspection. A week later, my amplifier arrived at their facility. A short while later they informed me of what the problems with the unit were. They also informed me that a restoration of the unit was possible. I gave them the green light and my Sansui AU X1 was added to their wait list. In about 4 months, they started the restoration. The restoration took 3 months and my unit was shipped back to me in May 2013, complete with a service and performance report, and all disassembled and replaced parts.

I was impressed to find out that my unit was now not only fully compliant with the manufacturer’s original specs but was capable of delivering a wonderful soundcolor as well. Since then, I have been using the amplifier… As far as I know, Cherish44 is one of the few service providers for the Sansui AU X1 in the world. Their customer communication is also top-notch. Bill Ersoy took the time to explain in detail what was being done with my unit while the restoration was proceeding. Cherish44 means great service and management... -  S.R., Ontario, Canada
