Carlsberg don't make knobs, but if they did.. It would reach the parts that other beers don't.  The volume knob can give a real impression of quality on amps IMO. If you get a large, weighty one, it just feels better for finer control. That by itself can give the impression of quality in the mind and affect the subjective opinions of gear!! The other one is decent connectors. It just puts the mind in the right place and the amp 'seems' to sound better. |

Well, I'm finally a proud Ember II owner after quite a while of lusting after it.
I have a beginners question regarding the input attenuation...
How does this differ from high/low gain on the Ember 1? It seems to serve basically the same purpose. Is there any sound advantage or disadvantage to one or the other? Is it really all about how much play you have on the volume knob or is there more to it?
Thanks!

There is a small difference in the input attenuation.
On the Ember 1 attenuation levels are fixed and can be bypassed by a jumper.
In Ember 2 the attenuation module works the same but you can pop in a module with a higher (or lower) amount of attenuation if needed.
Somewhat more versatile.
There is also a technical difference.
The input RF filter is located AFTER the gain resistors so in low gain (high resistance) frequencies above 50kHz get some roll-off where in high gain mode the input filter works above 500kHz.
On both high and low gain there is no influence within the audible range in phase or amplitude though.
In the Ember 2 the RF rejection input filter is not changed by the set gain and is always above 700kHz.

I had 2 guys explain to me on Head-Fi why the Ember was a terrible amp:
Guy #1: It's a safety hazard. Kids and small animals are at risk due to the open design.
Guy #2: He prefaced everything by saying that he's not an electrical expert at all, but had read some articles on Stereophile that explained it all to him. And, according to his reading, he can now predict whether an amp is good or bad solely by the THD #s, which according to him are not very attractive on the Ember.
Can anyone remind me why I even bother...?

There are a lot of nutters on Headfi. I saw some other self-professed audio producer saying that it was better to double amp. Guy #1 - what kind of power does he actually believe is going through the Ember. Guy #2 - ask him if he's met Jesus yet. He was good at predicting. It's not on the Ember Review thread is it? I'll bait him.  |

Can anyone remind me why I even bother...? @ guy #1: safety hazard for kids: hot tea/coffee on the edge of a table, small things they can choke on, chemicals not tucked away are all much bigger hazards. Haven't heard of people getting killed by the Ember. Besides ... it works on 48V DC which is officially considered a safe voltage to touch (indoors in a dry room, not inside a bathroom). It is about the max voltage that can be used safely in open frame designs. Safety hazard for small animals ? I think more small animals get killed by nibbling on power cables than inside the amplifier. What's not very safe is when it drops to the floor and glass fragments, of the once so mighty tube, are all over the floor and you step in it while walking barefooted or on socks. guy #2 should be getting some real education on this subject, stereophile may not be the best 'teacher' after all. |

I have 3 cats two dogs and a wife. The only person that has been hurt is me. I stupidly touched a tube too soon after it had been turned off. I got better. |

Can anybody reassure me that it's alright to continue using a standard 6SN7 to 6DJ8 adapter in the Ember? it sounds fine but just wanted to check I won't damage anything or I was not compromising the sound in any way. Apologies if this has already been implied in the technical explanations already posted-I'm not at all technical-that's my problem. Thanks.
