My review (which I thought was up already at TMA) for the newest version, is being republished at the moment. My prior review of the FiQuest was overall positive. MST have fixed every audio issue that I had quibble with making a nearly perfect portable (and massive) amplifier. Those are documented in my 2010 FiQuest review.
 
Soundwise, too, the FiQuest has taken a leap forward, where, prior, it was merely very good and powerful, MST seem to have grabbed what I would call a house sound that consists generally of best-yet percussion and liquid mids. Please look out for the new review. It was published, but went private accidentally. I've found a few areas that need to be fixed up anyway for it. Will update this thread with new information.

Is it a different size now?

Size is the same but there a number of improvements under the bonnet which discerning listeners will probably love b

Has the board changed?

Here's a problem: my original fi-quest is with my dad in Canada. So, comparing the two directly is hard. But there seem to be no major layout changes. Ryuzoh mentioned that in this version (which can get pricey) only the absolute best parts were used. From the outside, the amps are the same, but the performance is different to be sure. I will post my main review this evening.

Interesting. I have all Black Gate non polar in the Super E configuration and I use Tantalum resistors with some modification on the volume control. There are a few other tweaks as well.

Yes, you surely can tweak the FiQuest to your heart's delight. As a platform, it is nearly flawless. That is one of its strengths. In fact, in terms of overall utility, MST hooked into the right (perfect) platform. But as you and I know, it's more than just the platform. I'm in love with the midrange energy of the Mad Max version. In love.
