Accuphase C2400 How does it compare?

I sort of figured this wasn't a popular model preamp as there's so little information. But it is intriguing.

So there is some love for this preamp. Don't know how it would sound with a Pass Labs X350.5 but it's definitely on my need to consider list. I'm down to about 4 preamps to choose from. The others are Pass XP20, Aethetix something, Esoteric C-03 and now the Accuphase.

To sum up my question regarding the Accuphase, I was curious to know what signature, or, what might set this preamp apart from others as it seems to me (a guess), that it might be either very nuetral and accurate because from what I remember about Accuphase products in general, that's what they are, accurate. Or it may possess a specific signature to them or to the specific model I asked about.

I can't roll preamps. My last pre was a Cary SLP-05. It was great but I found myself spending a lot of time rolling tubes. I had a lot more time to do just that. Now I have a 10 month old and would rather "play" with Jr than to roll tubes. I spent a fortune on NOS tubes. Don't wish to repeat that either. (Yikes does that add to the cost). That being said I understand how tubes can really add to the "music" experience and I'm really passionate about the music. So a tube preamp isn't out of the possibility as long as I can easily dial it in and with some models, this appears to be the case.

Any insight is useful.
