Jolida Fusion DAC Pre - Active Tube Preamplifier with a full DAC and Bluetooth (Silver)

I am using this as a pre-amp to the amp side of my Marantz 2230 and the sound is wonderful. Very easy to connect via Bluetooth and streaming audio from Spotify sounds far better than you'd ever expect. CDs are brought back to life as well. Appears to be very well made and you'll never confuse the remote with any other remote because this one seems to weigh a couple pounds. I'm very happy I bought this after my first 4 hours straight of listening. It's also cool to think that the tubes can be switched out down the road, but I'm pretty happy with the stock sound!
