Entry level tube integrated to replace T-Amp?

Hi!

I'm currently using a T-amp with a NOS Dac (Derek Shek's) with a pair of original Snell K. I'm very happy with the set-up and amazed at how good things can sound at budget level. However while the Snells are tight, swinging, very open and aery, and delivers great soundstage and image with the T-Amp, they are also somewhat "bleached" in sound (as I've seen them described by someone). The T-Amp is a bit "thin" overall and creates a certain listening fatigue. The Snells are last on my list of updates, and I am therefore considering replacing the T-Amp with an entry level tube integrated to compensate for the Snell's somewhat "bleach" sound and the T-Amps somewhat "thin" sound, as well as to make the listening less fatiguing. I'm aware of at least three well reviewed tube integrateds: the Almarro 205, the Sophia Baby, and the Decware Zen. Is there anyone who has heard and compared those three amps and could give me some advice? PRaT (as the English say) is very important to me and I would vey much like to keep the T-Amp's good soundstage, image and detail.

Feel free to comment!
Thanks!
