L70 topping předzesilovač mě překvapil svou kvalitou jak zvukově tak materiál funguje jak má

I have a background in electrical and audio engineering, and previously used the Topping DX7 Pro for a few years which I used to drive a 2.1 active speakers+subwoofer setup, as well as headphones and IEMs (its biggest flaw, albeit small is the high output impedance on the headphone amp which can affect the frequency response of low impedance headphones). I had intentionally picked the DX7 at the time because it was an all-in-one integrated DAC+amp, but more recently, I purchased a MiniDSP Flex to use as a DAC with the benefit of getting Dirac room correction (which gives a better resulting sound than I can ever get playing around with just PEQs in REW and Peace in Windows). So now I was in the market for a headphone amp and speaker pre-amp. Enter the Topping L70.The Topping L70 lets me keep the single-ended 6.35mm, and differential/balanced 4.4mm and XLR headphone plugs that the DX7 had, while acting as a pre-amp to my active speaker setup connected over XLR (the subwoofer is directly connected to the Flex, only the bookshelf speakers get passed through the L70 as a pre-amp). With the newer features this offers (improved HPamp which provides more than enough power with >120dB SINAD on both the balanced and unbalanced plugs, volume memory, up to 21bits of dynamic range resolution to take advantage of 24bit audio), I would consider the L70 endgame material that can be paired up with any discrete DAC of your choosing, especially at its price point.

Ein völlig unbrauchbares Verstärker der sich weder über Zone 2 noch 3 anschließen ließ. Die beigefügte Fernbedienung hat ebenfalls nicht reagiert.
