Maybe TAD amp is just no my cuppa and I should move to Soulution. Will keep you posted. Thanks for the supportive thoughts.I really have no clue Ricco - Maybe try to have a dealer / friend to lend you one Soulution preamp to try, this would be the best. Sometime in hifi the best of each brand doesn't give the best results. Synergy between components is key. I believe it's more safe to stay within the same brand for the preamp/amp matching (whatever the brand).
Vitus is excellent and known for its relaxed / smooth / big sound but could be a little slow compared to TAD gears. On the other side TAD sound is faster, more clean but never dry or lean, more "neutral" (if it really exists). It is known that TAD is rarely "love at first sight" because of its neutrality and lack of showing off in specific areas. On my (biased) opinion fast and less coloured gears will always give you more room to fine-tune according to your own taste. For example you can easily "slow-down" your system with the right cables (Acoustic Revive / Audioquest / Furutech /...) or smooth the overall sound presentation with the right DAC (Lampizator / Aries Cerat / Abbas / ....). Also don't under estimate your speaker positioning and try different placements if possible to match/compensate the characteristics of your room.
Good luck and keep us posted
