So I have my DHT Pre quite a while ... .
My first impressions were mixed. -Although Vinnie's description of the sound was quite accurate, in comparison to the AVC-tube module everything was a bit too laid back. S. Ebaen‘s description in the first part of his DHT PRE review shows it well and coincides with my experience.
But after 2 weeks regular use the sound changed clearly, I haven't changed my setup. Suddenly speed and punch was back in my setup.
Now, I can not believe what kind of music comes out the Lio. I use the LIO with dac, DHT PRE and active speakers. In addition I regularly use the LIO headphone amplifier and my desription applies to both setups.
I am now looking forward to the experience from the tube tour and maybe I will experiment with other tubes (unfortunately I can’t participate the tour). But it's hard to imagine that music enjoyment can be increased considerably in a Hifi setup (with similar expenses).
The second thing I will mention, is the expandable concept of LIO – exceptional! Sure some upgrades will not come cheap but you have the choice!!!
Closing remarks: I havent’t been in the hifi hobby for almost 20 years , comeback with LIO is joy beyond compare
Thank you very much Vinnie !
