What is output power on the custom Citadel or
does it put out the same as the regular?

What is it’s purpose against the regular version?

Does it use the same input tubes as the regular?

It would seem to handle the 1266 TC just fine as it is close to 2 watts which is what the XI Audio Formula S puts out.

Read here & here for the answers to your questions.

Don't recall Sonic saying anything about the custom Citadel sounding different from the regular Citadel. So looks like just aesthetics. Different chassis, output tubes. Drivers appear to be similar.

I'm building a custom Citadel right now. Will take power output measurements when I finish it in a few days. They will be close to the regular Citadel.

It's only the output tubes that differ from the stock Citadel. The 6P7S tubes will yield slightly higher voltage swing. So more power into high Z headphones. But, I mainly use the 6P7S for aesthetics in the silver version.

So being that eventually be an owner of the Citadel decided to see what popped up on eBay for the 6P7S and there’s a lot in quads. I’m bad at trying to decide on something so abundant. What brands should I focus on? No, have no intention on tube rolling as it’s not needed.

Brand for 6P7S doesn't matter. They're all Russian tubes, either Foton or Svetlana if I'm not mistaken. Very good and linear tubes and still cheap! You could also try the American tube 6BG6 which (almost) has identical specs as the Russian 6P7S. The 6BG6 is not as plentiful and cheap as the 6P7S though.

The amp is now finished and I made the output power measurements. As expected they're very close to the regular Citadel. So close that it's not worth noting as you won't notice any difference in power.

Here're some pics =)

What a beauty, evoking master craftsmanship like fine art at every angle. This one somehow gives me the impression it's small. Would you be able to take another photo with it against something like a known headphone, soda cans, etc. for a point of reference on size?

This is absolutely gorgeous, right down to the beautiful vibration control feet.

The big questions now....what's the price point on this custom Citadel???

No more heat sinks?

Have a look at Joseph's pictures. He has it side by side with the Woo Audio WA33. That will give you an idea of the custom Citadel size.

Thanks for the nice comments! I really appreciate it!

The amp is boxed up and ships out today. But, the exact dimensions are stated on my website. Check the Citadel page.

Thanks!

The price for Silver Citadel is 2550 EUR with no add-ons.

There's plenty of heat sinks on the inside that are directly mounted to the chassis. Nothing is getting overheated

It’s a big amp

Here are a couple of photos of my CC next to my GS-Xmk2 for reference.
Neither are big amps.

I've had my CC running for 4+hrs at a time on several occasions and it doesn't run hot at all, only slightly warm.
In fact, my GSX-mk2 runs warmer.

Have you notice CC being more enjoyable than the GSX?

I enjoy both very much in my chain.
