Maybe too detailed

Just purchased CEC TL51X transport to replace CAL Audio Icon used as transport which broke. Expected nothing new--bits are bits, right? For some reason, everything is more detailed, but almost too much, bordering on "digititus." Some recordings are not enjoyable because every flaw is exposed and highlighted. The sound was hardly lush before, but its detail was not off-putting. The D to A converter is a Tact 2.2XP which is essential for my awful room. Amp is BAT VK60, which you would think would ameliorate any harshness. What's the amswer . . . a tube preamp after the Tact to control volume and soften things up? Your thoughts appreciated.
