Dan,
to answer your question;
i cannot describe my impressions in terms of frequency response. it is more the ability to resolve the music's stoping and starting with levels of precision.
i owned the XV-1s for a year. in direct comparison to my 'then reference' the vdH Colibri the XV-1s rounded and blunted transients. again; this is in direct comparison. i also owned a Koetsu Rosewood Signature Platinum at the same time and the XV-1s was much more clean and detailed than the RSP like the Colibri was compared to the XV-1s.
the 'character' each of those cartridges imparted a level of transient agility which was unique. OTOH the RSP had this glorious luscious mid-range tone, the XV-1s slightly less so, and the Colibri much less so.
the A90 falls somewhere between the XV-1s and the Colibri....about perfectly between the 2. yet it has sufficient levels of tonal weight to be 'right' and has that ease which was so fleeting with the Colibri.
the word 'obscure' i suppose infers a shortcoming or problem. that is not the feeling i intended to relate. it's more like a scale and a balance. the XV-1s and the A90 are at different points on the scale of various attributes depending on your perspective and priorities.
to answer your question;
Can you give a frequency range where you think the XV-1s obscures bass?
