ciphercomplete, let me know if you're interested in one. I'm might be putting mine up for sale soon. It's a great amp, but I need re-coup some funds from a 300B amp that I recently purchased.
Almost pulled the trigger on a Woo 3+ with the Teflon tube base upgrade and then I see this thread using the search button. Man something to really think about now?? I will order something in the next week or so. Gotta love this hobby!
After hundreds of hours of research (mostly on head-fi), I decided to pull the trigger on this product. I'm fairly new to the high end HP scene but I think I will like the qualities of this amp based on the input from you guys. I am also in the market for a new set of cans so input on the best match to the CSP-2 would be highly appreciated.
I have a set of Sony MDR-V6 cans that I have been using for years (18?) that are not a bad product IMHO. I have spent some time with the H650s on several occasions, and maybe it was the amplifiers used, but I was not impressed (sources seemed distant). I like the K701 cans better because they seem more engaging, but not sure if they are a good match with this OTL amp?
I have a huge sellection of JDJ8, 6922, 7308 tubes (one of the reasons I bought this product) but specific input would be great especially when matched with HP recommendations.
Thanks for all thoose who posted to convince me to plunge!
I've had pretty good luck with a wide variety of headphones and the CSP-2. I'd say overall get the headphone you like the most - the CSP-2 should be able to do a decent job with it no matter what.
As for tubes, I liked the Amperex Bugle Boy 6DJ8's best, and I am using the Sophia Princess 274B rectifier, although the Mullard 5U4G sounds at least as good if not better.

OK I'll go for the AKG K 701 (or maybe 702?). I've got several Bugle Boy 6DJ8 tubes and I am very fond of these in other equipment. I've got some old Tesla (non JJ) E88cc tubes from the 60s that I am also very fond of. My favorite 6DJ8, 6922, 7308 tubes I use in my First Sound Line stage are Mullard CV2493 E88cc tubes. These are military spec gold pin tubes that I get out of Europe. They are not cheap but I have found nothing better.
I've read up on the rectifiers so I'm sure to try a few of those also.
I wonder how this amp sounds when paired with HD800s. Also, being an OTL design, how does it compare to Zana Deux? I would not be surprised if Zana is better, but still I am curious about it.
I was checking Tubedepot and I have seen a lot of 6DJ8 variants. Telefunken, Siemens, different amperex tubes etc. Does anyone have an experience with Telefunken and Siemens variants?
Thank you for the reply. There is one variant of amprex at Tubedepot, a NOS one, priced at $120 here: 6DJ8 / ECC88 AMPEREX
Is this the one you are mentioning? When I listened to the HD800s, I loved their detail and soundstage a lot. However, I also wanted a bit more lows in addition to all its sonic qualities. BTW, Beyer cans are too dark for me and I did not like the sibilance with GS1000s for example, just to give an idea. Will this amp with the amperex tube do the trick then?
