Yey, nice product so far. Thanks social security card replacement

none so far

The Atma-Sphere MA-1 Mk II. 2 offers an utterly clear and uncongested view into the music. Transients have snap, percussion moves at breakneck speed, and cymbals have a lifelike, steely sheen. All of this imparts an immediate quality that will have tube nay-sayers who "like accuracy" scratching their heads. divorce lawyers dayton ohio

All applause! Security fence systems

I just received mine yesterday and will submit a long-term evaluation after a few months of use. Regards, Arlington

I do not have any as of today

I got mine in Pearland. This is a definitive purchase for me.

None at all.

New Roof Construction Look so nice!!!

Love it so much!!!

I have received two days ago a new pair of MA-1 MK 3.3 fully loaded (with VCaps and Powerboost add-ons). It is not even properly burned-in yet, but I’ve just had the most spectacular listening experience in my life! I’m thrilled!!! MA-1 & MP-1 MK 3.3 are impressive, outstanding and totally fantastic! I’m listening to them with a pair of old pairs and heavily modified Soundlab A3. The synergy with A-3 is exceptional. The sound of Atma Sphere combo is simply spectacular and stunningly beautiful. It outperforms by light years anything else I’ve had or listened in my life. Please notice, I’m far away from being a beginner in the audiophile world. I owned EAR V12, 509, 912, Quad II forty, eighty, 606, 909, I have tested or used a couple of McIntosh, Primare, Jadis, PassLab, Spectral, and many fine machines I do not remember any more. I was afraid of the heat coming from 38 tubes, but finally, it does not heat so much. I find it acceptable in my moderate-size listening room. My other concern was the size of A-3 and the synergy with MA-1 (many audiophiles buy very powerful transistor amplifiers to drive them) but their curved shape actually works just fine in moderate size room and the synergy with MA-1 is the Perfect Match! I will receive in a couple of weeks a new DAC, but even now, on my budget CD player, I have the most fantastic sound I have ever experienced in my life (my previous DAC was Big 7). I fully and totally understand how privileged I am to own Atma Sphere gear. If you have money to buy it, do not look elsewhere! If you live in France (Paris area) and you would like to listen these magnificent amplifiers, feel free to contact me. My skype nickname is twodolphins and you'll find my various posts on french audiophile forums as well. I’ll be happy to invite you for a listening session. As many other guys do, I like to listen and compare various gear. This time, I’ll gladly compare some new DAC, turntable, cables (I use Magnan’s and WhyNot), but in a matter of amplification, for me things are settled. I will not bother to try listen anything else anymore. This is a definitive purchase for me. I am in a state of Nirvana. Truly exceptional amplifiers and a pure and utmost joy.

As for I am concerned MA-1 amplifier or MP-1 preamplifier do not have any weakness!

Exceptional soundstage, tons of power

VERY hot, large

Currently, I am unable to split the two systems (music/HT), so the amp has to be capable of both. Here's the current rig- Lexicon DC-1 v2.01, Rega Planet CD, Snell E.5 (90dB, 4 Ohm) towers.

First, the contenders:
Krell KAV-250, $3300, marked down to $2800
Anthem Amp-1 (tube), $1299, marked down to $744 (!)
McIntosh MC352, $7000 (used for reference)
Atma-Sphere MA-1 Mk1 (tube), $6000, used $3000

The setup(s):
The first setup was the Atma-sphere amp with the Atma-Sphere MP-1 tube pre and a Sony SACD player through Vandersteen 3A's. The Vandy's were well out in the room- over 6 feet from the front and 4 feet from the sides, approx 6 feet apart. I was around 7 feet from the speakers, 5 feet from the back wall. The room was heavly modified with traps and panels.

The second room was all the other amps through a Mac MX332, Mac MCD7010 CDP and B&W 803's. These guys were about 10" from the back wall and offcenter in the room by about 3 feet with the right speaker only 2 feet from the wall and 6 feet apart. I was around 7 feet from the speakers. It was fairly bare, with another 802 setup opposite, behind me.

The review material:
Radiohead, OK Computer, "Exit music (for a film)" and "Lucky"
Braveheart Soundtrack, "Betrayal and Desolation"
Pink Floyd, DSOM, "Speak to me/Breathe" and "Us and Them"

The reviews:
The Atma-sphere's were first. PF's "Breathe in the Air" was absolutely mesmerizing. Oh. My. GAWD. It's like somebody plopped Waters' head about 3 feet behind the speakers, right smack in the middle and he was singing right at me. Un-freaking-believeable. I was like a little kid again. Smile all the way across my face. It sounded THAT good. Unfortunately, the more I listened, the worse it seemed to sound. "Us and Them" lacked the impact I was used to. To put it bluntly, there was zero Bass. None, zip, nada. Moving the chair around helped, but it was still anemic at best. Hmm- the only thing I can come up with is that maybe the room was overdampened or the speakers were too far out into the room. The speakers got good reviews in Stereophile... Radiohead's "Exit music" was stunning until bass was asked for, and "Lucky" again lacked bass when called for. Hmm. But the midrange! Vocals were simply STELLAR. I can't beleive how realistic it sounded! My first "You are there experience", and it boggled the mind. The braveheart track was simply pathetic without bass- I purposely picked this track because of it's huge transitions- from bass drums, timpani's (sp?), and horns to violens, it's got enormous fluctuations. It sounded quite flat.

The Anthem came next at a different store. Immediately, slightly more forward sounding than the Atma's, it also completely failed to present that "you are there" impression. However, bass was nice and tight and quite abundant. Well, so much for that "Tube amps lack bass" arguement. This one poured it all out for me, though without the liquid midrange and holographic imaging that the Atma's presented.
Switched over to the Mac, just for kicks to see what I was missing. Much darker- almost intriguing and seductive. The soundstage was narrower and still lacked the depth of the Atma's. However, I found that it was perhaps a little too flat for me- not lively, not involving, but still VERY nice sounding. I liked the Anthem better, I think. However, take note: The anthem was turned up more than the Mac (unknown to me, of course..) I couldn't help but think of Eyespy's DBT testing: "The louder one will sound better". Ugh.

Enter the Krell. Pink Floyd, "Us and Them". This amp was much brighter than the Mac, with more depth and a wider soundstage. It lacked the bass control of the Mac. Again, the volume control had been turned up (damn that salesman), but only slightly. I fixed that and played the Braveheart track again. Drums had authority, but throughout the passage, a french horn blasts along, either irritatingly or beautifully. This was irritating. I found that I wanted to turn the volume down. I think the Mac won... Otherwise, it had presence and a nice wide stage, if still not very deep.
Return of the Anthem. Gone was the irritating French horn, replaced by a midly annoying horn, but with much more layering underneath. I could make out the details of the rest of the orchestra previously muddled up by the Krell. Overall, I like the Mac, but for $7000, there's no way.

I finally brought the Atma-Sphere's home for a demo on my own gear and what a difference it made. The bass had authoity (almost frighteningly so) and the soundstage was still terrifyingly real. I really don't have any words to describe it except perhaps "magical". I don't know why I even considered anything else nor why I hadn't made this purchase earlier. If I'd only known what I was missing! Simply put- this amp will never leave my listening room. I can see myself upgrading every component in my system except this one.... Trully a remarkable amplifier. If you have the means and the urge- you owe it to yourself to listen to this amplifier.

The bad's (and every piece out there has them): it runs hot as all hell. You can turn the heat off in your listening room 'cause you won't need it. Also, it draws obscene amounts of power (~500W each) so your electric bill will be adjusted accordingly. Finally, biasing is not as easy as some newer amps in that you have to switch the "+" speaker cable to the "bias" terminal to bias it; then move it back to listen. Just a slight hassle.

Overall, this amp rightly deserves 5 stars since it is by far the best amplifier I've ever heard.
