Mcintosh C-2300 first impressions


I bought an C2300 from an authorized mac dealer with return rights minus shipping. I have 11 days to listen to it. My current preamp is the Counterpoint SA-5.1 that has had the line and phono stage upgraded by Mike Elliott (the original designer/engineer of Counterpoint gear). Since I use a low output cartridge, I also use the Counterpoint SA-2 in conjuction with the SA-5.1. My amp is the Jadis Defy 7 MKII. What I was hoping to achieve was to retain all of the sound quality of the SA-2/SA-5.1 combo while lowering the noise floor compared to my current phono section (the line section of the SA-5.1 is very quiet).
My initial impression from my first night of listening is that the C2300 has a refined, polite presentation in a button-upped British sort of way with a sweet top end. However, it sounds thin much like a SS preamp sounds and it doesn't have much in the way of a bottom end which can even be heard on acoustic bass. Forget any type of wowie-zowie bass punch with this preamp. Voices also don't sound as real as my current preamp. And these listening impressions come from listening to LPs, CDs, and 15 ips 2 track tape. I guess if I didn't know any better I could be happy with this preamp, but unless things improve soon it will be going back.
For those of you who own and love the C-2300, I would love to know what preamp it replaced in your system. I love all of the creature comforts this preamp has to offer with 8 inputs, 4 sets of balanced inputs, a cool remote, etc. I do think it is a bit garish looking in person with different shades of green lights as well as blue. If this preamp doesn't start fleshing out more of the music, it will be going back. And please don't tell me that it takes magic Telefunken 12AX7s to make this preamp come alive. I have heard mixed reviews with some owners not liking the Telefunkens at all and actually preferring the Mcintosh selected 12AX7s while others who are hooked on Telefunkens of course swear by the improvement they expected to hear.

Oscar, I never thought the 2300 would be a significant step up from the SA-5.1. I was just hoping it wouldn't lose any of the magic while providing the extra inputs and features you mentioned. The 5.1 is a tough act to follow in terms of its sound quaility and it appears the 2300 is not up to the task. What I was most interested in is if others who own the 2300 think there is anything missing on the bottom end and if they think it is rather on the thin side across the audio band or if this is just my perception.
As far as I'm concerned your observations have little or no meaning as you have not waited for the C2300 to break-in properly... wait until the 11 days are up to let us know something we can really use.
I agree with all the above observations and suggestions. It needs to break in and will take most of your demo time to do so. I have the C2200 and it improved significantly once broken, had the stock power cord replaced with something better, used some decent footers AND the stock tubes were replaced with Mullards and Amperex. There is no shortage of impact on the bottom end.
On Day 10, switch out the stock tubes for some decent ones. I use NOS RCAs in my C2200. I don't have golden ears, but I heard an immediate improvement. It's a tube preamp and the quality of tubes make a difference!
Like others have said... You can't expect to optimize the sound of a tube preamp without excellent NOS tubes. Selecting & installing the right NOS tubes made a night & day difference in my Aesthetixs Calypso. You will be selling yourself woefully short if you don't experiment with NOS tubes... suggest you start with Mullard CV 4004 platinums from Upscale Audio. It won't be cheap, but it will take you listening experience to a new level.
