Review on AIYIMA Tube T6 PRO Bluetooth 5.0 Tube Preamplifier - Hi-Fi Headphone Amp, Vacuum Tube Preamp for Home Audio Amplifier, Wireless Receiver, Audio Decoder, Preamp PC-USB DAC with APTX by Robert Aan

This is amazing technology. I have a basic kit consisting of a laptop, an APO software equalizer, a BBE maximizer, a switch, and two sets of powered speakers (a pair of Beringher studio monitors and Edifier speakers). I thought I had a very good sound. That was until I tried this wonder preamp. Tube processing is such a big deal and after trying three different types of tubes I found one that takes my music to a new level of clarity, soundstage and clarity never before possible. What is striking is the difference between the instruments, the natural resonance. Also, I have to thank Aiyima for their amazing technical responsiveness and quality of support. As I was experimenting with different valves, I had an issue with a set that had a loose contact pin. Luckily, instead of blaming the preamp, I contacted support and got advice on how to fix the problem. Now I enjoy the best music. This Tube T6 adds a new level of harmonic depth to my listening experience. I highly recommend this preamp! own).
