Pass Labs INT 250 or XP12 and X150.8

I did a search and couldn’t find much about Pass INT 250 against Pass XP12 X150.8 combo.

I am planning to get a reasonably inefficient speaker in the Kudos 606 ( specs say 84 db, but real life measured 82db) however doesn’t dip below 8ohm.

The prices is almost the same for either, the added convenience of Balance adjustment and HP bypass with the dedicated Pre XP12 is handy and preferable to me.

But if the INT 250 is superior sound wise, I’d take that over convenient features like I just mentioned.

Any thoughts ?
