True, though you really only need those parallel resistors on a transformer coupled tube amp. In any event, I'd still be curious to see what the guts of the CanOpener looks like and what kind of resistor arrangement they have on the pcbs.

True, I guess if the Can Opener is only designed to run off SS speaker amps then the higher watt capacity parallel resistors wouldn't be necessary.  Just had that tube-based configuration on the mind this whole time...I guess then it would be possible to make an in-line setup without the box.  A setup with the high watt capacity parallels would cover every amp option though.

In order to keep output impedance low, I would use a 4-5 ohm resistor in parallel. Or if I needed attenuation off a particularly powerful amp, each leg of the parallel would be two resistors in series and I'd tap the headphone output off the midpoint. 

 

edit: taking that further, use a rotary switch to make a series type stepped attenuator (only need 3 or 4 steps). The first position can be open to give direct output, and the rest of the steps will have the paralleled outputs in varying ratios

That would be quite neat and very useful

We're getting a little fancy here!

Say you want an output impedance from the amps perspective of less than 30 ohms, how much would it be possible to attenuate?

post #1357 of 3639

Is there any amp with taps about the size and weight (circa 1.5KG) of the

M-Stage amp around 50 watts that could be bought instead of Emotiva, while coming close to the sound/price/basic idea of outdoing headphone amps ?

 

Shipping and import taxes on the Emotiva quite steep if sending outside North America....

I've been enjoying the sound out of my Nuforce Icon and Centrance Dacmini PX (mini shootout here: link)

 

There's also the Firestone Big Joe, Travagans Red/Green, Trends and Topping have several varieties, Temple Audio in the UK as well with their Bantam line, etc.

Thanks Armaegis....going to check them all out now ! I'd really love the Emotiva but not really practical due to its size.

Heya,

 

So just reporting in after a good long time with the Emotiva.

 

 

I used to use a pre-amp to add additional tubiness (it was a Little Dot MK III acting as pre-amp) and enjoyed the volume control and additional warmth. I have since reverted back to just my tube DAC (Maverick TubeMagic D2) and the Emotiva mini-X itself without a pre-amp. The reason was I felt that it was degrading the overall end product sound due to the distortion of the tubes on the Little Dot. I think a higher end pre-amp would do what I was doing, without the distortion, but as it is, old noisy tubes on an entry tube amp are not something that really increase anything, but rather, introduce noise and other small imperfections. So I've removed the pre-amp.

 

I've been using this setup now for months (Emotiva A-100 Mini-X, Maverick TubeMagic D2, Hifiman HE-500 [mods: detachable miniXLR cables with flush miniXLR inputs on each cup, speaker tap cable; all by Brian at BTG Audio; faux leather padded headband that snaps around the stock band; still using hifiman velour pads]).

 

Very clean presentation still. No noise floor for me still unless I turn the volume very high and hit pause. Extension is wonderful. I do not find this to be brighter than what the HE500 was on other sources. It's not a dark headphone, but I wouldn't call it insanely bright either. I found some Beyers (770, 880, 990, T70, etc), SRH940, Denons, Ultrasones, etc, all to be brighter than the HE500 is by a little bit. I think the HE500 just presents it as it is. Some things are supposed to be piercing (violin). Mids are still as natural as ever. Same great sound stage. And the bass just pulses like life itself. It's delicious. I generally prefer warmer sound, with a slight sprinkle of bright on top, it's my sugar, but on the whole it's a fairly neutral setup. I don't find the Emotiva overly coloring anything that is super noticeable.

 

Been killing two albums recently. Daft Punk's latest (RAM), and Glitch Mob (Drink the Sea). Really interesting details on these albums in the back drop of the sound scape, things out of focus, but amazing how you can still pick them up on headphones (didn't hear things on speakers at lower volume).

 

Anyhow, still going strong. Still enjoying this setup. I haven't even looked at other equipment in quite a while. It's still ever as satisfying. Feels very end-game to me still, months down the road.

 

I also still use my D5000 with resistor (500ohm) and Premium DT770 600ohm with the Emotiva as well. Everything going great, no issues, no noise floor, just wonderful power and a sleek look.

 

Still highly recommended.

 

Very best,

thanks for the update! really enjoyed this thread and will be my reference when I got myself a he-500..

Very best,

This is the way I'm feeling. The Emotiva feels like end-game to me for some reason. Not tempted by the Schiit Mjo, Burson Solosit, Bryston BHA-1 or (put anything here).

 

If I had a LOT of money to burn I guess I could always use a GS-X-Mk2/ or Cavalli Liquid Gold and I'm sure those will be much greater than the Emotiva,

 

But otherwise I'm very happy and not looking to upgrade. The Emotiva is shockingly good. Much better than the Lyr IMO (yes, even with upgraded vintage tubes)

 

This is the same way I feel about the Concero: shockingly good. I think I've hit my sweet spot and not really looking for anything more with my music. The Concero/Emotiva combo is so much better than the Bifrost/Lyr, it's kinda funny actually.

 

Down the road I'm considering adding another LCD-2 for those days I feel like being hit in the face hard with bass or feel like being trapped in a closet with lush mids. LCD-2 = sitting in a closet with Scarlett Johansson in your lap--you forget you're trapped in a small muffled closet as she's singing into your ear.

LOL and at the end he gets an eargasm. Yup. Singing.

But seriously, M-13, quit head-fi now. You've hit that sweet point. 

 

A few weeks back when I had LCD-2 and HE-500, I was thinking about getting Senn HD 600/650 or maybe some DT880/DT990 and just call it a year or a summer. Not sure how I went from that to a LCD-3. I swear it happened out of the blue in less than a week, wasn't even planning it. I've tried the Emotiva with HE-500, LCD-2 and LCD-3. I think the best combination I had with the Emotiva was the LCD-2. The LCD-3 feels as if it's being limited by my current source and amp, more so than I felt with the other two.

 

Around the same time a few weeks back, I was thinking for my computer stuff upgrading from E10 to ODAC. Then it went to Concero. Next to M-DAC and then Anedio D2 and for the past 2 weeks have been at NAD M51. Although I've been hearing about the good prices of Perfect Wave MkII. So now there's that as well. So currently at M51 and PWD mkII. I somehow increased my budget by a factor of 20 over a month.

 

Just go ahead and quit man.
