I have an XCan with PSU power supply driving Grado 325s. Considering the Ety 4p and looking to move to the cosmic.

any comparison thoughts out there between the two amps?

I can't comment directly on the Cosmic, but I used to own an X-Can/X-PSU, and now have a Maxed Out Home and Total Airhead. The Maxed Out Home ****s on the X-Cans from a great height. But so does the Total Airhead, so I'm guessing the Cosmic would also blow the X-Cans away. (You can probably tell I'm not a fan of the X-Cans.)

LOL! That's not a phrase I've heard before. Had me in stitches, RossMan.

Jude, it's funny how on the internet you can use a phrase without thinking which is very common in one part of the world - even a cliche - and it's completely new somewhere else.

heh, I have to think and stop all the time when using Aussie slang, most of it's rather offensive and can be taken the wrong way or doesn't make a lot of sense

I'd like to know how the cosmic sounds compared to the x-cans myself.

I used to own the X-CANv2, and currently own a Max. The difference is astounding.

Assuming the X-PSU improves the X-CANv2 slightly, and assuming that the Cosmic is a bit below the Max... the difference should still be mighty big

I have the Cosmic and it is a very nice amp, but at that price you might consider any number of top flight amps, including a Melos, Berning ZOTL, or Earmax Pro. Any of the three will drive your 325 or 4p, and will blow away the Cosmic. The great advantage of the Cosmic is portability. If that's of no great importance to you, I highly suggest you look into one of these suggestions.

I do want portability so I'll have to decide from that point. I guess we'll see some XCans and PSU go up on ebay in the next few "daz"

OK, X-Cans suck!


X-Cans is a single-ended triode tube unit so it immediately blows away any solid state unit, assuming enjoyment of music is part of your listening criteria. Solid state/transistor components add grain and distortion on things like sibilants and cymbals, sort of a "white noise"effect. So, as the drummer said in "The Commitments", they're "F*@#ed for starters". Tubes are more in tune with reality and the real sounds of instruments and voices. They are more dynamic and more able to separate instruments and keep their composure during loud passages. They also keep low level detail fully apparent, even at low volumes. With tubes, it's just the music, without an electronic glaze or hash woven into it.
Transistors mask and distort.

If you are not listening to tubes, you are not listening to music. You are listening to noise and distortion.

Easy!
I too am an ex-xcan member but I'm taking the high road and will not bash it. (well not too much!

)

Good point:
Great midrange.

Bad point:
midrange was great only if you had the right can (580/600) and tube. (JJ teslas for non NOS)
Bass was very loose but did tighten up with the addition of the X-PSU.
Treble could be very harsh with the wrong tube (stock JANs)
I have heard that some nice NOS amps or teles would cure this but they could go for as much as you paid for the amp)

That wasn't too much bashing was it?

Part Two: 'When Tubes May Not Be Suitable'

If you value clarity and transparency, and do not care for the slight "compression to bring up low level detail" characteristic of tubes, you might try a Grado RA-1 battery driven SS dual op-amp headphone amp. If you want to spend a little more, maybe a HeadRoom Supreme? But spending thousands of dollahs for a SS amp that won't give you the improvement per dollah ratio you deserve, don't bother. If you are rich and don't care, go for it.

Ross, even though you think the X-Can is a crap product, I'm curious what you thought was so wrong with it...Just to compare notes.


The X-Cans is a cheap solid state amp masquerading as a tube amp. It uses cheap solid state components, including a 20c op amp chip as its gain stage, and then adds a couple of tubes at the end to try to give some tube softness.

And that is exactly what it sounds like - a cheap solid state amp with some bad tube sound added to the mix. It sounds thin, grey and cold (like a cheap solid state amp) with a bit of tube glare and softness thrown in (like a cheap tube amp) - it is the worst of both worlds.

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 ...

This is, with the greatest of respect, ********.

Tube amp distortion is measurably higher than solid state - orders or magnitude higher. It is the distortion of tube amps that adds their characteristic sound and it is the distortion which you are enjoying listening to. Nothing necessarily wrong with that, but it's true.

Tubes are soft at the bottom end and rolled off in the high frequencies. Good solid state amps beat the hell out of any tube amps in this respect.

Good solid state amps are faster and more dynamic than any tube amp.

To my ears, all tube amps sound, to varying degrees, soft, slow, rolled off, and glassy. You hear things differently, and that's fine.

Tubes vs solid state is a question of personal preference. I prefer solid state, having heard and owned many tube amps. To say that one is objectively "better" than another or that one is "more in tune with reality" is complete bollocks.

Thin, grey, cold? You must have a defective unit. It sounds nothing like you describe, at least not with JJ tubes. 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.
