No, only my RS-1 and it was not one of my favorite pairings.

That was not my question!

My answer still stands: No I have not tried those Grados with my Canamp (I don't get your joke, if there is one). SR80 is the only Grado-phone that I've given a shot - they didn't get much better - the sound was the same.

EDIT: Being european, I don't know **** about your Grados

Just got one of these amps and initial impressions with the K701 is very positive for me. Love the tonal balance and clarity, especially from SACD.

Enjoy this amp, it really shines with K701

Hiya there fellow canamp owners. I have one question about this thing. I received the canamp today and have burned-in it like 3 hours by now and this thing runs hotttttt. Is this normal and is there any known issues considering this thing? The volume knob almost burns my hands.

Any experiences?

Thanks!

The CanAmp runs in Class A mode all the time. That is to say that from the moment you turn it on, it's going full tilt, only being limited by the volume control. What effort that is not being required of it is being dissipated in heat. This is normal of SET (Single Ended Triode) Tube amps and Class A operation Stereo amps.
While I'm sure the volume control is unusually warm, it won't burn your fingers.
The case can get hot and, like the heat sinks on big class A amps, you'd think twice about leaving your hand on them, they still won't get so hot as to leave a burn mark on you. Just uncomfortably hot.
Give it good ventilation and it will serve you well for a long time.

On a side note, break-in really does take quite a bit, more like 200 hours and it will turn a corner, breaking in.

One more stupid question. So the amp keeps heating and is hot all the time if it is turned on altho no audio is played thru or volume is turned to zero? ;< So I have to turn it off from the backpanel to make it not to produce heat?

Well... it doesn't keep heating... it stays very warm (hot) at all times. Like I mentioned before, from the minute you turn it on, it's running full-tilt (regardless of volume up or down).
If you don't want it throwing heat around you, you'll need to only turn it on when you want to listen through it. Yes, that means reaching around the back of the amp to hit that rocker switch.
It won't take it long to get back up to ideal operating temperature anyway so you should be fine turning it on and off as needed.

From Heed's product description:
"The CanAmp is a two-stage amplifier. While the first - voltage gain - stage is based on an integrated circuit of the highest audio pedigree, the second - power gain - stage is
a single-ended, pure Class-A amplifier. It enables the CanAmp to drive virtually any headphones from 32 ohms up to 600 ohms. The unit has no internal wiring, and the signal path is kept to a minimum on its PCB. Its high-quality, 1 dB-tolerance Blue Alps volume pot goes through a further selection process during manufacturing to achieve an even tighter, 0.5 dB tolerance."

So it is fine to keep it ON 24/7 without a worry of heat causing damage to the unit?

I tend to just leave mine running since I never know when someone will come over to audition headphones, I'd like for it to be ready right away. Also, I never know when I'll have some quality headphone listening for myself so, really, it's probably more the latter.. lol

 

[mrarroyo]

blazarian if you are really concerned or if you live in a very hot climate w/o A/C you may wish to explore:

1. Turning the amp off when un-attended.
2. Using an fan to cool the area.
3. Mod the case by drilling holes on the bottom and the top, perhaps installing heat sinks. Of course this is very extreme a measure and will void your warranty. So I would do as Dan or at the most 1 and 2 above.

Cheers.

Hi,
It's like an old platitude repeated ad nauseam, but to be able to experience how good K701/K702 are, you need a high quality (read: [relatively] high power) headphone amplifier. Together, they sound just right - there is good bass, sound has "body", plenty of details, yet there is still a lot of air, space between instruments.
K701 with CanAmp are very neutral to me, which means they play music "as is", with all its beauty, but also they reveal every mastering faults. If you have high quality music - they are a blessing, but with some recordings - they are a curse

Cheers,
Adam
