I'll take swell....It's going to sound swell!
Astell&Kern new flagship A&Ultima SP2000

It's your own choice.
I bought the sound of SP2000 running FW 1.10 in the retail store, and I convinced that if AK changes this key factor (sonic performance), it should be an opportunity to roll back OR to return the device. The sound of FW 1.10 with fixed clicking issue — the SP2000 is the King.
1.19 was on all our demo units at CanJam NYC and on the loaner units we had in other booths at CanJam NYC.
Well, if that's the latest version I'm good to go! That unit sounded shockingly good to me, and if its worse than previous versions (which Jason assures us its not) ignorance is bliss!
There is also at least 200 hours of playback time on our players that we demo at shows if you believe in burn-in, which is another highly debatable topic. .
Not debatable to me, lol. Ive had a few instances where i had to return a player and get a new one and I can hear quite easily the difference burn-in makes.... When I was an electronics technician, when we built mil-spec parts, we had to run the units on burn-in, under load, monitored with oscilloscopes and DVMs etc, in an oven for 1 month, because specifications drift over time and under load.... Its not 'spooky science,' its fact.
The FiiO M15 has made me a full on believer in burn in, that DAP went through some crazy changes within the first 100 hours.
Yes, I had the same thing with the M11 Pro.... It was like a roller coaster there for a day or 2...

I've read so many theories on burn in. The most knowledgeable audio engineers don't claim to fully understand it. Then again, they also don't claim to understand everything that makes a product sound good, even ones they've designed. They know what they hear and what people like. It's the same with burn in. Companies like PSAudio, Zu speakers, etc. learned the realities of burn in through the number of returns they got when they didn't burn in their stock.
Yes, sir. Will have to spend at least a week with it, it's open box off Amazon, but it could only have a few hours on it. Often people will buy a high end unit, not understand what they have, listen to it for an hour then return it. I doubt it has 1 or 2 hundred hours on it... Plus I just got the 1950s cable the other day, its actually showing the limitations of my se100, which blows my mind; never knew a cable could be so revealing, its astonishing!
Ill have some eye candy tonight!

It is called “Drift Parameters”, and any electrical engineering designers should have known it as it is a very basic knowledges. These parameters changes and drift away upon operational circumstances. Over a period of time, these parameters with a constant applicable circumstances becomes more stabilized due to the tolerances and the whole operation Of the systems including Temperature coefficient, ESR, DF....etc...
These Operational drift parameters are different from “Degradations overtime” or “shelves life degradations”. It is only found by applying a constant voltages in and out at a constant ambient temperature over a long period of time. Until the present or modern date that it became so pronounced with better high precision tolerances components, that it had to be disclosed in data sheets
For example this one from Vishay and pay attention at this.
Once again, it is from within Basic Component engineering designs, and if any engineers who don’t acknowledges....is likely a low grade engineers or the know nothing...because they can’t even read data sheets....unless “denying the facts” for business/financial purposes
Can you hear the differences ? That is out of the questions
Even Sony have to published it so. However, not all people can comprehend the Facts, and accept the facts, or both

What’s the 1950’s cable?
It is the pw 1950s cable. A VERY popular pairing with the u18t or a18t or many other IEMs.
It is very well known amongst asia and in USA, the pairing is always very popular.
In Asia specifically Hong Kong they worship this pairing, literally.
I let mine go recently due to budget limitations, but that cable was one of the best I ever heard.

It's utterly phenomenal and its not even fully burned in.
It also retails for $2,000+. I was super lucky to get one used and mint for $1,200
