You snagged me on this one! My audio engineer friend has been working with the 6N6P for 25 years, and says it is just Fantastic! He likes it much better than the 12 AX AU AT series. I’m very interested!
Fantastic video- really quite remarkable staging even for a YT video (on Sennheiser 620S headphones). Very clear and well placed vocals woth good instrument separation and detail retrieval as you reported. I’m definitely down for this pre-amp.
Sounded great! I have a nice pre, a clone of your E80CC , also sounding great! I will be into building your headphone amp. I already have a BH Crack, sounds good, but I hear some margin for improvements on that one. :-)
Very cool. I've built both of your other preamps & I'm ready to try the new one as soon as it's ready. You mentioned it would take 6dj8 family which I'm a fan of the 6922 types. The tube in the preamp now seems like it performs well though. On future builds please leave just a little extra space for bigger film capacitors 😁 You guys have some nice new stuff coming out. Awesome 😎
@@NosEL34 one of the design directives to Charles was to leave some extra space for larger coupling caps. Unfortunately unless we enlarge the chassis there just wasn't any available to spare. With a much more affordable design, keeping the cost down was important. But interestingly the Vishay caps that I chose sound amazing and they sweep very wide band, something like 10hz to 20khz -1db with most of the response dead flat. Personally I'd recommend building with the Vishays and listen to them before even thinking about trying something else. We also use the Vishays in the Universal Phono Pre, and in that circuit they also sweep and sound way better than you'd expect.
@@matthewhilty4209 we'll always have our "Classic" lineup, for some larger amps, you really need the strength of that 3/16" thick top plate. But the work (time, inventory and money) to release 2 different types of chassis for the same Kit probably precludes offering them for the odd customer who wants one. Creating a more affordable line introduces it's own set of problems!
I would choose the smaller black chassis as well if it was available. I do own one of their Cherry plinth enclosures..they are very nice looking in person.
@@Kulpa-Systems it will be available for Test Builder's this Fall, then once it clears them it will go to the general public. To see the Kits currently available I've put a Link below the video.
wow, even on youtube that sounded fantastic !!

Your amps have such a natural ease of presentation, without hint of electronics, beautiful work.
@@mfr58 Thanks! As audiophiles ourselves, we work hard at creating great sounding and affordable audio gear.
Each of them is very desirable to say the least
i will definatly be getting that OTL Heasdphone amp in either chassis , very nice

I'm digging the modern one. Nice job!

Really like the classic line chassis for the headphone amp. Would also be curious to hear which headphones you liked on it?
Our favourite headphones to use are the 150 Ohm Sennheiser HD660S, but the budget 80 Ohm Beyerdynamic DT770 Pro also sound great.
I like the smaller black chassis, but as a special request keep 1 or 2 wooden cases for customers who want matching equipment.

Hello, when can we bought this preamp?

Have you tried transformer based volume control?
We have not, but we have developed a passive stepped attenuator kit that fits on the classic line chassis and provides excellent performance.
