More on ss/vs tubes vs hybrids

I am using a Monarchy Tube DAC with an Ayre Axy7e. For me this seems to be a reasonable ss/tube hybrid compromise. (in another forum, a few audiogoners commented on this as type of solution as well.) I just put Amperex/Holland 6DJ8's in the DAC and am really enjoying the sound of the DAC coupled with the speed and clarity of the Ayre. Changing tubes has a noticeable impact on the sound.

I am curious to hear opinions about this compromise and have some questions:

1. Would the reverse be a better compromise (or just different), a good SS DAC with a tube amp? (no, I am not going to throw out my CD's and go vinyl :)

2. Does using tubes down the line, (DAC, pre, AMP) compound the harmonic distortion issues with tubes? and possibly also the transient response? I have found transient response to be a key factor in reproduction of timbre.

Thanks!
