My first experience with tubes, a couple years back at this point, was with a feliks echo mk2 comparing to a JDS Element mk3 (using the Element DAC for both), and at the time I remember being really underwhelmed. I found the echo a little hazier, a little softer but I had expected a bigger difference. I ended up sticking with the element because it was much more versatile and didn't give tubes another honest try (apart from a few days with an Elise) until the Cayin HA-3A which sold me. It helped that at that point I had improved the rest of my chain, my listening skills and also my expectations.Comparing three amps via my CD player. Going RCA out to the JDS Atom 2 amp, optical out of the CD player to the Element III Mk2 boosted and RCA out from the Element III into the Echo Mk2. Using JJ E88CC gold pins in the tube amp. Listening via my HD600 (marble colour). Honestly I really don't hear a difference between the three. If there is it's very minimal. Now granted both JDS Labs are likely the same amp. Just one is a DAC/amp combo. But I would have expected the tube amp to sound noticeably different. But that is not the case. Maybe if I swap tubes there might be a change. I'm using a jazz CD by Charlie Haden. Am I crazy for not really hearing a difference? Many of you have pretty expensive gear and claim to hear a difference compared with the cheaper stuff. Perhaps JDS Labs has just really outdone themselves. The Echo Mk2 seems to be a fairly well regarded tube amp so if the JDS Labs can hold its own against it I guess that's a testament to JDS Labs. Also two different DACs are in the mix as well as the CD player has a Cirrus Logic DAC.

I also remember having so much noise through my computer in the Echo at the time that I could audibly hear my mouse moving around and minimizing windows.
