I got the tubes here, and sprung the extra few bucks for a matched setWhere did you get those tubes? After I get this amp back from Amir, I may try some tube rolling.
Sadly, I don't have any other tubes for this amp (yet). I have been using it exclusively with LISST after I found that I subjectively preferred their sound. Curious to see that Schiit have now discontinued them, I wonder why?
I'm just curious how they are managing the low gain. If it is by means of a resistor the output impedance might be particularly high in low gain mode.It was grounded. I assume output impedance is independent of input gain.
From listening you probably would never notice a 2nd harmonic at -90 dB. The only headphones I don't use with this thing are IEMs, since I can hear the noise floor with those. But who knows why I'd even try using IEMs on something that can put several watts into them? It rocks out with a pair of Beyer T1s.Weird...
I have a Lyr 2 and it sounds super clean yet powerful to me...
I would have guessed that it measures way better than this in the Sinad department
I find this sort of thing incredible. Someone could easily plug in-ear headphones into this thing, and whether or not it was the amp that went wrong or what was feeding it, the idea that something non-'medical grade' and potentially >8W is connected to something right in your ears seems... foolhardy. If the noise doesn't get you, the flames will. Maybe headphones are inherently fused..? Do we know that? Do we know that 'boutique' headphone companies know that they should be fused..? I doubt it. Why do people trust the design skills of these people at all, given their track record?It is possible though that DC could appear on the output (resulting in a loud and sharp 'tick' when the relay kicks in) that could destroy headphones.
Add to that TH-X00 drivers are 25 Ohm and the Lyr-3 can deliver peaks in excess of 8W in it (when something bad happens)

The excess power is so you can be sure whatever power hungry headphone you plug into it it will power it properlyI find this sort of thing incredible.

That was what I was thinking of when I said 'inherently fused' - but is it guaranteed? Guaranteed not to generate a large amount of gas, toxic fumes as it burns out? In your ear.I know of no headphones with fuses. It is not needed either as the voicecoil wires are so thin these burn out quickly.
This would be the opposite for tube amps.The excess power is so you can be sure whatever power hungry headphone you plug into it it will power it properly
Especially low sensitivity, low impedance Planars.
Those need immense power to sound as good as they can.

4W into 50 ohmsWhat would one call immense power ?
