X Cans Vs Headroom Cosmic

Ask any of the best recording and mastering engineers. Even they will tell you tubes are much closer to the sounds of real instruments than transistors


And who are these recording engineers, exactly? Names, please.

I don't believe you are likely to find any consensus on this issue amongst recording engineers.

In any case, recording engineers are probably the last group whose opinion I would consult on this or any other issue.

But Beagle is right, tubes do rock, and that is why I have a SET Zero Feedback MG Head DT, pure tube, not a lowly Ex-Cans

This is not necessarily true. I have an Earmax Pro and Maxed Out Home, as well as a couple of other solid state amps, and prefer the Maxed Home and the lesser SS amps. This is a matter of taste. If you prefer tubes to solid state, you would probably prefer the three tube amps mentioned. However, if you prefer solid state, then obviously this will not be the case. As to why anyone sould prefer solid state , see my comments below ...


I was talking about amps in the price range of the Cosmic, not a comparison of SS vs. Tubes. Your MO Home costs significantly more than the Cosmic; it also performs better than the Cosmic. To even approach a MO Home you would have to get the BS1 addition to the Cosmic, further increasing the cost. Regardless of your tubes vs. SS preference, I think any of the three I mentioned outclass the Cosmic's performance; while exhibiting various levels of "tubiness," none lack for speed, tight bass, or treble extension. The Cosmic is probably the best portable amp available, but even if you like the SS sound the Melos would kick the crap out of it in that arena (it's a hybrid, but sounds more SS than anything else with tubes).

Also, I dare you to find any headphone amp with bass than the Earmax Pro.

I'll take you up on that one, the RKV's bass completely annihilates the tiny, weak, powerless bass that comes out of the EMP.

Sorry but no "come ons" here, he did say any amp. That opens him up for prime duck hunting.

But Ross, why do you ask for names, then indicate you don't care what they think anyway? Tubes are for music lovers. Measurments are for people in white lab coats. It's what goes into your ear, and how pleasurable that is, that counts.

I'm most certain that SS measures better, just as I'm certain digital measures better than analog. Who cares? It's what sounds better that counts. It's being able to listen for hours and hours without developing listening fatigue or wanting to turn the system off because it is annoying or irritating.

Point of interest: To be fair, I put back the stock tubes in the X-Cans, gave it a warmup and did some listening. I had the following "observations"...

Overall sound was colored and slightly foggy, bass was rolled off and wooly. It was still smooth but lacked openness and clarity. It also pooped out at high volume. OK, now I was getting somewhere. I realized what Ross was referring to.

I went back to my Grado RA-1 and listened to the same source and same pieces of music. The sound opened up, it was much, much less blurry and foggy, and much more transparent and nimble, fast and light on it's feet. The bass was clean, articulate and more extended. The background was much more "black" and silent. A-HA!!

Everything I liked about tubes and the X-Cans seemed to be eradicated. What to do?

I decided, possibly in a panic, that the X-Cans needed some upgrading, so headed to Radio Shack and I bought a volume pot, a headphone jack, some silver wire and solder and also went to an electronics store and asked for their best risistors and transistors.

I know virually nothing about electronics, but I opened the unit up and replaced all the resistors ( I think) with the ones from Radio Shack. I also replaced the transistors (I think, the ones with two pins?), anyway, they looked about the same so I replaced them with the new ones. I then replaced the volume pot and the headphone jack. The volume pot looks weird and sticks out from the edge, but it was sound I was after, not cosmetics.

While I had the unit open, I rolled the tubes, back to the JJ's. I closed 'er up, plugged it in, and heard a small "pop". I plugged the headphones in and hit play. There was just a buzzing noise. I opened it back up and after scouring the board, I found one of the transistors had blown. I replaced that one with a red one and went back to listen.

Very disappointing. No bass, the volume crackled, and the treble was all distorted. The unit also began to smoke and smell funny. I unplugged the X-Cans but it continued to smoke. The odd thing was it smelled like cigarette smoke.

I opened the unit up yet again and there was a tiny tiny lepracaun, sitting atop one of the tubes, smoking a fag. He looks up at me and quips "Aye, ya see what happens when ya post bullshet about tuubes? Bad karma laddie"

Uh oh. And here I was, fresh from messing around in my DI/O's and thinking how easy the board in the X-Can would be in comparison. It would take absolutely nothing to upgrade the caps, throw in some Holco's...maybe even replace the op amps... I don't want trouble with leprechauns though

A Porche 911 is faster than my Ford Focus Station Wagon?

Damn... Maybe I should switch to tubes under the hood!

Because I wanted to know if there are any specific engineers who have expressed this opinion. It is easy to make unsupported assertions, such as "all good engineers agree with me", unless you have to back it up with evidence.

I agree. That is why I keep saying these things come down to personal preference.

Tubes are for music lovers.


Here is where I disagree. I am a music lover. I have over 1000 CDs and about 2000 LPs. There was a time when, for several years, I attended 2, 3 or 4 live concerts a week. I don't much like tubes and I much prefer my music on solid state. That is my choice, and I resent the suggestion that unless you are listening to tubes you are somehow not having an authentic musical experience.

I'm not saying that solid state is better than tubes, and I am certainly not saying that solid state is better because it measures better (although it does measure better). I am saying that I personally prefer solid state to tubes; to my ears, solid state is more musical and presents music the way I like it. I also happen to think it is more accurate, and accuracy is perhaps more important to me than it is to others. But these are my preferences, and I have no problem with others having different preferences.

PS a leprechaun talking about "bad karma" would certainly be an interesting cross-cultural experience!

Though I've heard neither amp, I wouldn't find it hard to believe.....

.....that is, of course, if we ambitiously assume the RKV felt like turning on when one was going to compare them.

Some names are Doug Sax, Steve Hoffman, Bruce Botnick. Their stuff sounds good to my ears.

I can certainly understand you personal preferences. Perhaps you find that tubes have their merits but they are out weighed by their shortcomings. I assume you find that solid state is your best overall option for musical enjoyment.

What I get out of all of this is that you should enjoy music with whatever gives you the most music. Enjoy and absorb the positive things and try to overlook any minor distractions (flaws).

Just like life itself...

Guess what? I just talked to Todd and ordered the reference module of cosmic amp. Originally I just want the Home but Todd suggest me to go for Cosmic for better sound. Now that is a nice person doing nice business!!

So next week I'll have both X-Can v2 with Cosmic reference module. I'll give you guys some introductory information as long as it arrives.
