Awesome! Any comparisons to other amps you own/have owned?

I had the WA7 just before the arrival of EF100, I think the later matches HE560 better with more power (more bass impact) and smoother trebles. But I guess WA7 isn't a great match for HE560 anyway. The only other amp I have now is an SR71A which works pretty well w/ HE500/HE560, but definitely lack of power when compared w/ EF100. 
 
The other thing I like the EF100 is that it doesn't get hot at all, just a little bit warm. That's a big plus considering the hot weather here in Singapore. The cooler working temperature is probably due to its class AB amp design. I kept the USB input  and speaker output OFF (don't need these features for now), that might be another reason.

Thanks for the impressions! I definitely understand about the heat in Singapore--lucky I don't have to deal with that now that I'm in San Francisco =) Have you tried tube rolling at all, and do you know what tubes are compatible with the EF100?

The tube used in the amp is 6N3J. I don't have any compatible tubes to swap, and I want to listen wth the stock tube for a while first. So far I quite like the sound already

Hello !!
And for the HE-6?? you think this amp is ready??

 

[Aurelus23]

i allready have the HE-6, and looking for the AMP

Hello !!

I think the rear speaker output (4.5w into 4ohm each channel) would be a good option for the HE6 if the front headphone jack isn't powerful enough.

Def not enough for the he6. Thats 4.5w into 4ohms not 50 ohms. That wont work.

I hope so too, I'm usually not a fan of hybrids and I'll be comparing it to my other tube amps

  I've been using mine for over a week now, really love its sound especially when paired with HE560. Haven't tried the built-in DAC yet, but the amp side is very good. 

How about on HE400i, the sound will be good also?

Has anyone tried it with an iPad? Does it need a powered hub?
