Just got the amp delivered, love the build, wish they gave a cheap power cord atleast!

But just plugged the M17 in lineout to this for initial listen, so far I quite like it! I must be a bit deaf since with Atriums, my volume pot is at 10-11 o'clock!

For burn-in, I just keep the device powered on that's it? No need to plug the headphones?

Aha..there are many opinions regarding burn-in for amps,
- Just let it on
- Play music no pink noise
- play pink noise

What I do :
- I just turn it on for SS amps for a day or 2,
- for tubes amps I play music for 4-5 hours everyday, let it loosen up naturally. Especially for class A amps i never turn it on more than 4 hours.
- For headphones or speakers I play music.

Hope this helps.

Thanks! Never burned a desktop amp before so this helps!

I actually did play pink noise through mine for the first 300 hours, then just kept it on 24/7 since and have noticed it keeps changing and improving. I actually don’t know if the THR-1 is class A (anyone know this?), but it barely gets warm after leaving it on for a while.

How’s the synergy with the Atriums? I bet the bass slam is crazy!

I've disassembled the THR-1 dozens of time for fixing purposes and trust me, it will never get hot with all the thick metal all around, it is a f tank.

Is it true class A or AB?

Do the internals get hot themselves? Or is it just that the thick metal prevents that heat from escaping?

I'm not really sure, let's ask @alvin1118 he knows 100%

It has aluminum heat sinks plus the case absorbs most of the heat

I'll just keep it on too! But yeah the Atrium sounds fantastic with this amp, bass is tight and slams pretty good and the soundstage is pretty huge too along with the depth.

This is not class A for sure. Class A devices need heat-sink on power transistors and THR-1 is without it on Exicons as you can see on pics above.

The exicons come with their own heat sinks and thermal pads between

Almost no amps are true class A. Most class A amps have very high bias but will switch to class A/B at a certain level of power. The THR-1 is too powerful to be true class A (would get much hotter), but it most likely has enough bias current to operate in class A at usable volume. If an amp has 1w in class A and 5w in class A/B, does it really matter if a that it is not true class A when most users use far below 1 watt?

 

[arijitroy2]

So after keeping it powered on for like 15 hrs only so far, now if I dial the volume pot till 9'o clock, it gets pretty loud, yesterday I go till 12'o clock when it was just out of the box.

This is not "true" heat sink, it is small. Look at other class A amps and heat sinks used there.

This is pure class A looks like, output power only 50W @ 8 ohm. Massive heatsink, large capacitor 440,000 uf.

*Property of Gryphon Essence
"Put bluntly, there is no such thing as a free lunch when it comes to pure Class A, so we state with no apologies: True, pure CLASS A means heavy transformers, very large heatsinks, lots of heat, lots of electricity, expensive parts and costly assembly."

 

[arijitroy2]

Can you folks recommend a DAC that pairs well with this amp? What am looking for is full bodied sound with nice clarity, what I don't want is where the treble is too soft!
