Air Tight ATM2 Direct Driven by CDP?


Does anyone have experience using the Air Tight ATM2 KT88 amp direct-driven from a CD player with a variable output? I have a Cary 303/300 and I'm thinking seriously about purchasing the Air Tight amp, but I want to avoid a preamp if possible. I realize the ATM2 has a two-channel attenuator as well, but what does it sound like driven directly from the CDP? My Cary has audio output levels of 3.0 Vrms single-ended and 6.0 Vrms balanced.

I have owned the ATM-2 and ATM-3 monos. The ATM-2 continues to be one of my favorite amps. I did try running the CDP ( Wadia ) directly into the ATM-2. While it worked fine, I did prefer the preamp, which at that time was the First Sound Deluxe. The dynamics and soundstage were improved with the preamp.
Noble110,

I notice on other threads you've had experience with various preamps and the ATM-2. I'm now considering going this route, looking at Air Tight ATC-3, Herron VTSP-1, Modwright SWL 9.0SE, Acoustic Masterpiece C101, and EAR 834L. Any opinions? Other suggestions? Anyone?

I've had a lot of success using an Air Tight ATC-1 Pre with my ATM-2. Great MM phono stage. Not the most transparent pre in the world, it tends to sweeten things a bit. But overall very pleased with it.
Thanks. This is very good to know. I've seen ATC-3 Pres out there, but no ATC-1 pres yet. I'm now using the ATM-2 with a Thor TA-1000 Mk 2, which is fairly transparent, I think. It passes along every tube change in the Air Tight and can sound analytic sometimes, especially with 6550 power tubes and all Telefunken triodes in the power amp. I find I myself need to "sweeten" the sound with Mullards in the Air Tight input stage and in the Thor's 12AX7 positions. So, your ATC-1 Pre must contribute what's needed perhaps. However, all my listening is from a digital source--a Cary 303/300.
Bblilikoi: I have tried running my Ayre Universal player C-5xe to the Manley Steelhead's line-level input and the Steelhead's variable output drove a pair of BAT VK-150SE directly (as Manley's suggestion to avoid another electronic layer - preamp). I also tried running the Ayre through the Steelhead then Steelhead's fix output to an Air Tight ATC-3 to drive the BAT amps (i know..i can omit the Manley between the Ayre and Air Tight..but i just wanted to findout what effects the Air Tight had on this chain). To my surprise, with the Air-Tight in..the sound had more punch, more authority without sacrificing any of the transparency and I didnt notice any increase in noise floor.
With a side note: Ayre C-5xe's output is relatively low (1 and 2VRMS for DSD on unbalanced and balanced output, 2.05 and 4.10VRMS for PCM , respectively. Here are my points (after a long interlude):
1. If your source's output is low, it might not be a good idea to drive the amp directly using just an attenuator (in your case, ATM-2's; my case, Steelhead's)
2. Having an extra electronic layer might not always be a bad thing, especially if it is really transparent, and it can provide extra gain without adding too much noise.
3. Try and hear for yourself all the configurations, eventhough at first it might seem nonsense (as long as you dont do any damage to your system)
This is why i had to add the Air tight ATC-3 pre in my system and run everything (phonostage, CDP) into it instead of just using the Manley. The sound now is so much more satisfying
Best regards.
