Of course, the Air-Tight wasn't in the same league as the Copper, but still, I was surprised by the sound of the ATM-1.\u003C\/p\u003E\u003Cp\u003EThe ATM-1S has now succeeded the ATM-1 but it had a great run since 1986 until 2010. And now Air-Tight's model range extends even further. So this 'classic' little amplifier was a nice insight into the Air-Tight sound.\u003C\/p\u003E\u003Cp\u003EThe ATM-1 is a 36w push-pull amplifier with a unique CD direct input control. So on the front panel, we have two RCA direct inputs. An input selector which allows you to select the front or rear RCA inputs. And two attenuator controls for both
2L \u0026amp; R channels. Attenuator controls on a power amp? Well, in this case, yes. Passive? Maybe. These controls can be handy for source equipment with a high output so you can adjust it accordingly. Or, this power amplifier can be used as an integrated. Handy for some I suppose but to me, a little odd. Especially when they made a matching preamp too!\u003C\/p\u003E\u003Cp\u003EIts successor, the ATM-1S has the same controls but with some differences. The 'S' stands for 'Special'. The main difference of the Special version is that you lose the valve 5AR4 rectifier valves as it uses transistorised rectification and a user-adjustable biasing system.\u003C\/p\u003E\u003Cdiv class=\"separator\" style=\"clear: both; text-align: center;\"\u003E\u003Ca href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEhCdHrZXWk7xqP38tHrdlMd54fk_jK0zZeaSHsas3G5FSebVzIvoX9GuKUDdxD5wQJHQIwS9uSzg5LoLELIaz154Q_iW0oWjRfpRjFULkiAu4cBkwiBgdOeqYFTyk6trCLoL6trbl6DgT_vFEOaFm2ZI_xdYT7SKmQNsf7Lm2maoseg_FsZDc296sGfzm2q\/s866\/TANNOYISTA_AIRTIGHT_07.jpg\" style=\"margin-left: 1em; margin-right: 1em;\"\u003E\u003Cimg border=\"0\" data-original-height=\"609\" data-original-width=\"866\" src=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEhCdHrZXWk7xqP38tHrdlMd54fk_jK0zZeaSHsas3G5FSebVzIvoX9GuKUDdxD5wQJHQIwS9uSzg5LoLELIaz154Q_iW0oWjRfpRjFULkiAu4cBkwiBgdOeqYFTyk6trCLoL6trbl6DgT_vFEOaFm2ZI_xdYT7SKmQNsf7Lm2maoseg_FsZDc296sGfzm2q\/s16000\/TANNOYISTA_AIRTIGHT_07.jpg\" \/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003Cbr \/\u003E\u003Cp\u003E\u003C\/p\u003E\n\n\u003Ch2 id=\"how-does-the-atm1-sound?\"\u003EHow does the ATM-1 sound\u003C\/h2\u003E\n\n\u003Cp\u003EThe ATM-1 with 36wpc in Push-Pull should match my 15\" Tannoy Monitor Gold loudspeakers (LINK) quite well, so hooking them up along with my Croft preamplifier, we're ready to go.\u003C\/p\u003E\u003Cp\u003EI set the volume controls on the amplifier to around halfway at first before opening them up to full.\u003C\/p\u003E\u003Cp\u003EStarting with vinyl, I thought I'd start by playing something gentle and Tales of Us by Goldfrapp was my first choice. The first thing I noticed was the amount of air in the sound and how full it was. The detail retrieval was quite surprising as it was almost immediately noticeable that the mid-range for Alison Goldfrapps's vocals was quite lush. Whilst the bass wasn't as prominently voluptuous as I was accustomed to, the first full play of the album started to give me a signature to this compact amplifier.\u003C\/p\u003E\u003Cp\u003EI carried on with something more modern and a favourite of mine, The Wonder Stuff, Never Loved Elvis. This album has lots going on, but it's not as articulate as the previous album which goes for many albums recorded in the 1990s. But still, the swirl of the music came through, the speed of the delivery was very nicely done, and, although the more complicated cymbal splashes weren't disappointing, they weren't quite as smooth as I wished for.\u003C\/p\u003E\u003Cp\u003EMy next choices were a mix of both vinyl and digital including Leftfield, Seal, Curtis Mayfield, Spiritualized, Lou Reed and after a few days, I found what this amplifier really liked and what it had in common with. I found classical was probably its main love together with 60s\/70s rock was where it's at, which is very cool as I love the psychedelic rock era.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EBut for me, something more modern, bass-heavy, dance or some DUB, it managed them well enough. One thing that did impress me was that it was very articulate at lower volumes, and by giving it something with more energy at a reasonable volume, I found it impressed me enough to be addicted to its charms.\u003C\/p\u003E\u003Cp\u003EIt's a great thing and will be a very worthy piece of kit in any system.\u003C\/p\u003E\u003Cp\u003E\u003Cbr \/\u003E\u003C\/p\u003E\n\n\u003Ch2 id=\"the-build-quality-of-the-atm1\"\u003EThe build quality of the ATM-1\u003C\/h2\u003E\n\n\u003Cp\u003ELet's look at the build. From first impressions, it's a very compact and solid amplifier.\u003C\/p\u003E\u003Cp\u003EWeighing in, this little compact amplifier weighs in at 22kgs. The main chassis is made from mild steel and coated
2in a very nice charcoal grey. A very nice finish, whilst underneath, a nice copper-coated polished steel panel.

Detail and the midrange presence, bass on gentle recordings were sublime. A romanticised delicacy and speed on slower tracks. Low-volume bass.\u003C\/p\u003E\u003Cp\u003EWhat didn't I love?... Not much, but it could have done with a smidging more grunt and grip for anything complex at volume. Not easy to bias.\u003C\/p\u003E\u003Cp\u003EWhat could be done?... I'm absolutely sure that the ATM-1 could now be slightly upgraded to be less of a shrinking voilet, and to have a little more grunt.

2LEAK Point One preamplifier.

The SPM600 really kicked out the jams with even more clout and slam.\nNow the Dali's were really singing. The flatness almost vanished with a richer, more open and\ndeeper sound stage.

The\nPioneer was unbalanced so this was something to look into.

But ... saying that:\n\n\u003C\/p\u003E\n\n\n\u003Cp\u003E\n\nThe Pioneer RT-909 still wins hands down. The pace and the smoothness made the PD-91 the\nwinner on this front.

The CPM2600 by itself is a wonderful unit for sure. But, it may have a rather\nuninteresting sound stage for some. Coupled with an external amplifier, Chord or maybe\notherwise, it makes for a very nice unit to own. So, why have an integrated if all you're using is\nthe preamp circuit?\n\n\u003C\/p\u003E\n\n\n\u003Cp\u003E\n\nWell, indeed ... But, for some the integrated on its own will be perfectly fine.
