Email us with any questions via our website and get personal feedback from the design team. This unique unit is NOT a 'clone' or a 'copy' of any other product. It truly is unique in its use proprietary technology - which was designed in the USA. These units are hand-assembled and calibrated in the U.S.; by members of the design team. After-sales support is available from our highly qualified US-based team. Don't let the sales numbers on eBay fool you. It has proven to be our MOST popular model since being introduced in May 2021, followed by the MM-6 and then the MM-5. Our corporate website had built substantial traffic flow by the introduction of the MP-7, whereas many people 'found' the MM-6 through eBay. Please note that purchasing is also available on our company website with a full range of options. PayPal and Apple Pay, and credit cards are accepted there. Read extensively about our products, design philosophy, and look through our extensive database of competitive products with commentary (use a search engine as we can't place the link in here due to eBay policy). Zero Feedback, Single-Ended Class-A Gain Stages - No Op Amps (Integrated Circuits) for more natural sound, cleaner crescendos and minimal listening fatigue. Dual-Tiered Power Supply Regulation with a total of 180dB of Line Rejection for tremendous 'punch', low-end power and dynamics High Headroom Passive RIAA equalization High-Voltage J-FETs - NOS (New-Old-Stock), hand-matched with hand-tuned operating points deployed in a maximum-inherent-linearity configuration Highest quality local decoupling networks for best soundstaging Pure Film and Foil Polypropylene Interstage coupling network with extended bandwidth Front Panel: Silver.
