We picked a date/time and asked for (1) Flat Mount and (1) Swing Mount and they had the parts at a reasonable price. Constant communication up to arrival, which was great. Marcus arrived in a company vehicle with all his equipment and the two mounts. Marcus was awesome, he slipped on shoe covers before going upstairs. We showed him what we wanted and he went to work. I told him that if he needed help to mount the TVs once he placed the mounts on the wall to give me a shout. I went downstairs, and barely heard him working. He worked so quietly that my nervous pup didn't even bark or get anxious. Marcus worked fast, told me he was done, and he had the TVs mounted on the wall. The swing arm mount is perfectly placed and moves smoothly. It is just what I envisioned and hoped for and no mess. Marcus gave us the different payment options, price was as quoted with no changes. Marcus told us to call if any issues. I highly recommend Marcus & TV Geeks !!!

From the most knowledgeable, sophisticated audiophile to a person who has only recently discovered…read morehis/her love for music--and for that vast segment of the musically attuned population between these two extremes--one need look no further than Gramophone in Timonium, Maryland, for your high-end audio needs and desires. Gramophone carries the very best in all the categories and groupings that constitute the vast repertoire of audio equipment: bookshelf speakers, floor speakers, CD decks, amplifiers, turntables, receivers, sound bars, isolators, precision cabling, and much more, exclusively featuring only the most reputable, trustworthy brands in the high-end audio equipment market. For the nascent audiophile who is a recent entry to the world of high-end audio and who might be challenged by the dizzying array of available high-end audio equipment that graces the market, fear not, for Gramophone's employees are the most knowledgeable, skillful, and passionate in the business, bar none. Of equal importance--and perhaps even more so--they are willing, able, and sincere in assisting you in whatever way possible, since they instinctively know that the purchase of high-end audio equipment is a deeply personal, serious decision and one involving a substantial financial investment. Case in point: in Spring 2025 I made the leap from an owner of a reliable, intermediate, matched stereo system that had served me in good stead for decades to a complete high-end audio system consisting of Yamaha, Sonus Faber, Marantz, and Tascam audio equipment. The Gramophone employees assisted and guided me at each step along the way as I assembled a high-end audio system that met my needs, musical tastes, budget, and personal expectations. The end result is that I am now the proud owner of a complete high-end audio system that fills my home with exacting, precision, enriching sound quality that I have so keenly desired for such an extended period of time. Another category in which Gramophone is unmatched in the world of high-end audio is that it stakes its very reputation on standing behind every product that it sells its customers. There is a personal situation that I encountered with a product--a Sonus Faber Lumina I Bookshelf Speaker--I purchased from Gramophone a short while ago. While time and space do not allow me to go into great detail about this situation I will personally attest that Mr. Justin McMahon, one of the Gramophone high[er]-level managers, took care of every detail that impacted this situation and replaced the defective Sonus Faber Lumina I Bookshelf Speaker and its mate with a pair of brand-new Sonus Faber Lumina I Bookshelf Speakers. It is demonstrative of the professionalism, courtesy, and laser focus on customer satisfaction exhibited by Mr. McMahon that has elevated Gramophone to loftiest pinnacle of exceptionalism in the highly competitive world of high-end audio equipment companies. Lest I be remiss in completing this review to my satisfaction I must also pay tribute to two other Gramophone employees: Joseph Moscatell and a young man named Daniel. Joe Moscatell has assisted and guided me in ways too numerous to mention throughout every step of each purchase I made with Gramophone, and there have been quite a few. Daniel is a young man whose knowledge of audio equipment belies his youthfulness. When I was researching high-end audio equipment it was Daniel who took great pains to explain in excruciating detail the functioning, performance, and harmonizing of high-end audio systems and how best to match components from various audio manufacturers to achieve an absolutely flawless sound quality. Having now passed mid-life I am no longer a young man; ergo, by this time in my life I have dealt with scores and scores of companies, with some ranked appallingly poorly to a few at the extreme other end of the quality continuum, thus earning a very high mark. As a consequence of dealing with scores and scores of companies, I have, out of necessity, developed a much-needed sixth sense for evaluating their overall quality, reliability, and trustworthiness. In all my many years on Planet Earth I am respectfully honored to state that Gramophone is, in all likelihood, the one company that has exceeded my extremely high expectations in every possible way. Keep up the outstanding work, Gramophone; your class, precision, and excellence absolutely do not go unnoticed. A supremely satisfied customer. Mr. Nick Glorioso

He even took some time to walk me through the details of updating the speaker system that runs through the whole house (the "zone" stuff).

Exceptional Customer Service from Start to Finish!…read more I cannot say enough good things about PowerHouseAV and the exceptional customer service we received! When our home's sound system stopped working, I reached out to PowerHouseAV and spoke with Matt, the COO. From the very beginning, Matt was incredibly attentive, responsive, and helpful. He quickly arranged for John, one of their technicians, to come out to our home and diagnose the issue. John was outstanding! He was professional, knowledgeable, patient, and extremely thorough in his assessment. After identifying the problem, he walked us through our options and helped us transition to a new Sonos system that better suited our needs. John returned for a second visit to properly install and configure everything. Once the installation was complete, he took the time to walk through the entire house with us, testing each speaker and ensuring everything was functioning exactly as it should. His attention to detail and commitment to getting everything right were truly impressive. What really stood out, however, was the level of service even after the job was finished. When I had additional questions about troubleshooting a speaker, John continued to be responsive and helpful, making sure I had everything I needed. It's refreshing to work with a company that genuinely cares about its customers and takes pride in the quality of its work. Matt and John went above and beyond, and their professionalism, communication, and dedication to customer satisfaction made the entire experience seamless. I highly recommend PowerHouseAV to anyone looking for knowledgeable professionals, quality work, and truly exceptional customer service. They've absolutely earned our trust and our five-star review!
