- Ember 2 is actually cheaper than the old SC model. We do not offer discounts as we already sell for the lowest price possible

The new version 2 Ember features:
- Line out disconnect when using headphones
- Input attenuation module for customizing input levels (not needed most of the time)
- Supercharger circuit built into the amplifier
- Revised layout and design

All of our designs can use both 6 or 12v miniature dual triode tubes. This just gives more options for tube rolling. Ember is auto sensing so just plug a compatible tube in and it will change settings automatically! 6v or 12v does not mean either is better, just different voltages on the heater circuit is all"

 

Thanks Asr for your help. I was asking about the P.E. version 1 because there are still some floating around new & used on the likes of eBay, and I would be really stretched thin to afford $350 for version 2 + ad'll tubes. I could just use the older posts in the tube rolling thread to find a suitable tube for the old version.

 

But from this email, I still don't know what a supercharger is or if the newer version makes much difference, and contrary to what he said I can find the old one for about $60 less.

 

I'll advise you to go for version 2 because of the added input attenuation module. The power of the Ember v.1 was a bit too much IMO for some headphones including high impedance ones like Senn HD 650. With the new module the Ember will be more useful with low impedance phones as well. When you add to that and the supercharger I think is well worth it.

^^^ Good input. Jeremy modified the low gain on my R1 Ember to further drop the gain for use with IEMs. With the R2 you can find tune the low gain up or down by just changing modules - pretty cool!

That's very interesting. In what way would you describe that effects the sound from the Ember giving it too much power? Too fast, or too distorted, etc? I always thought more powah is better :etysmile:

That's not how it works. You still only have the choice of low & high gain.

What the attenuation module allows is finer level control on the volume knob.

On the first Ember my HD650's were getting very loud withe the volume control at around the 10 o'clock position. That was on low gain.

On the Mk2, also on low gain, my max is around 2 o'clock.

This allows for much finer control of the volume even though the actual gain is the same.

I love it!

Another change that hasn't been mentioned by anyone is the removal of the constantly illuminated power LED at the rear of the amp. There's simply no need for it since the LED already underneath the valve already tells you the power is on.

These probably all sound like small things but the attention to detail has to be admired. Makes for a great user experience.

Don't even start me on how the 3-way output impedance options can be used to fine tune the sound of the actual valve itself.

Awesome!

Zorrofox explained it excellent. It was getting too loud for me at around 9 o'clock on the volume pot. With the new attenuation module should be perfect.
