Thanks for the compliment.

It is still, by my own standard, a case which was designed to a budget.
So I did not have all design freedom as I wanted (e.g. a even more sculptured front panel).

This is a very nice case.
How does sculpturing the front panel increase the cost, is it time and labour that adds to it, or just time on the CNC machine?

CNC time and fixturing, brushing time, and higher cosmetic reject rates.

It’s so minimalistic, maybe too sparse then again maybe not, it’s certainly elegantly understated, all of which doesn’t really surprise me from what little I know of Patricks taste.
It’s an absolute triumph, I had no doubt that this case was going to be very tastefully designed, my expectations have been blown away.

I noticed that there's no rca connection and the power socket is not of the normal 3-pin type.

The trick is not in the amount of visual features, but in the exact proportions that makes it visually appealing, to me at least.
But such kind words from a professional designer is some compliment.

If you have read all my posts about the balanced F5X, then you should know that a balanced input is a must. Hence no RCA.

The normal IEC 3-pin connector is too large to fit. The one shown here is Neutrik PowerCon. Widely available and typical Swiss quality.

Great work Patrick. I am definitely impressed!

I love the modularity of the case, and the ability to assemble and test large portions of the amplifier with ease. Being an engineer who deals with vibrational issues in buildings, I really like your vibration damping scheme for the transformers. Overall, its a extremely well thought out and visually clean looking design. Only thing its missing is some sort of cool F5X logo... =)
