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.

Happily, this is beginning to be a tale of two preamps. Yesterday when I posted some further thoughts, I was 99.9% convinced that I was going to send the big Mac back. I put my digital music server to its best use yesterday and had it streaming music to the 2300 for most of the day. Last night when I went to sit down and listen to the system, I couldn't believe my ears that this was the same preamp. The bottom octave that had been MIA was suddenly there and the midrange had fleshed out considerably from the earlier sessions. The highs were still sweet as they were upon the first listen. If I hadn't heard this for myself, I wouldn't believe such a transformation in such a short time was possible.

As for the comments posted from HP's review, Yes, I know about them and I read the review when it first came out. That review is the one that piqued my interest in the first place. I am also aware the latest issue of TAS also gave it an editor's choice award. The other comment was that if I sent it back, I would find myself missing something and I now believe that to be true. If last night's exerience repeats itself tonight (the music server is doing its duty again today), I can see that are things I would not want to give up.

Last night I mainly listened to LPs (still using the SA-2 into the MM inputs of the 2300) and reel to reel tapes (2 track 15 ips). There was an ease and naturalness that was bewitching. I am still dumbfounded what a difference a day makes as the saying goes.

If NOS tubes really take this preamp to another level (and the reviews on that seem to be mixed with some people preferring the stock tubes to Telefunkens), this could be a scary good preamp-specially if it continues to bloom as music flows through it.
I thought I preferred the stock tubes until I put the Teles in. I was blown away. Everybody is different so you never know. Sounds like it is breaking in.
So which Telefunkens does everyone prefer for the 2300? Smooth plates or ribbed for her pleasure?
Ah, sounds like the new tubes Mac installed needed to settle in. Please keep us updated during the process. This pre is a consideration as a mate to my McIntosh MC2102 amp, but I will say that some Macophiles @ Audiokarma have echoed your concerns in finding that the SS preamps such as the C46 counterintuitively sounded warmer and more fleshed out with better bass.

The smooth plate Tele is a touch warmer than the ribbed plate. I prefer the ribbed plate.
