Hello Garuspic: Have you managed to reduce earlier H2 distorsions peaks in the mid?

OK Wes S. To my mind it's a shame they didn't give them a bit more light. Would be very easy technically... In the other hand I understand they want to keep what makes the NH a very special bird.

Hello all, Did someone measure the NH carbon version? Wondering if they modified its fr response vs the old wood version. Thanks.

Hi, Answer is in my post.

My 2 levels mod's description: What is needed;: - 1 philipps screwdriver for tiny screws - 1 cutter - 4 self-stick felt pads for hard surfaces 1/13" to 1/9" thick x 1.57" to 2" diameter. Take a relatively rigid type.image: - 1 wood screw 5/32" diameter (no more, no less!), length has no...

Thanks for your inputs guys. I will work on the tutorial. To wait, here are some charts of the NH stock version: - comparison with my Kennerton Odin (green): overlays for 10 different positions of pad: Resulting power response: CSD: Busrt decay: harmonic distorsions at 100dB...

Hello to all nighthawk owners. I purchased a used NH some weeks ago. Why? Because it's the least we can say a controversial can. I love unconventional things. I wanted to hear this can and make my own opinion about it. And I like dying/moding, usualy speakers but also some cans. I listened to...

Thanks! However I regard Sorrodje to be the one and only inventor of the SDR. My latest and definitive mod was clearly closer to the Senn's S mod because I did fill the hole only with air, haha: in the inner hole: 2 layers of thin fabric to the outside grid and a perforated disc of creatology...

Eric,   Your translation of my post on HCFR is real crap! I wonder what headfiers will think about me

I own JAN Sylvanias 6SN7 WGTA and the Melz are a bit more dynamical and more powerful in the sub-bass range, so I prefer the later with my setup.

Umhhh... You are good to push Felik's fans into tube and adapter's rolling LOL Is this item the right one to buy?: http://www.ebay.fr/itm/1pc-Gold-plated-ECC31-6N7G-TO-6SN7-CV181-B65-ECC33-ECC32-tube-converter-adapter-/191259510368?hash=item2c87f48660:g:3-UAAOSwMmBVvXRv

What's the main sonic difference between ECC31 and good 6N8S like my Melz? (if you never heard Melz ones, I would say they are nicely dynamical and detailed, with an extended fr range, both on trebles and sub-bass)

Thanks Until for your advise; however TS 5998 seem to be always pricey and I don't want to go with adapters (ECC31)...

Hi guys,   My stock Svetlanas have a more extended frequency range than my 6080 Sylvanias but have a little bit too much upper-treble level for my taste and setup; thus I'm eventually searching for power tubes (so 6AS7G or specified manufacturer alternatives) having the most powerful sub-bass...

Hi guys,   I just edited the end of my review's post with some feelings about: - Sylvanias 6080 power tubes - Foton drivers - Melz drivers http://www.head-fi.org/products/feliks-audio-elise/reviews/13718

Yes Shaffer, these Foton render a very nice mid range, with huge contour of notes/performers ending with super natural/true tones; I don't hear little thickness in the lower-mid with the HD800 because this can surely lacks a bit of spl in this range. Melz are on the way, I am very curious how...

Hi guys,   A few impressions about my new tubes: First the 6080 Sylvanias power tubes: frankly, using the same drivers, I could'nt hear any differences between them and the stock Svetlana 6AS7G (6N13S); perhaps a bit of extended treble range from the Svetlana but not sure at all...   Now...

Seems Shaffer also, RCA 6080 (probably close to Sylvanias) and Foton 6SN7... in the first post in your thread:http://www.head-fi.org/t/765460/feliks-audio-elise-tube-rolling-guide-6sn7-6as7g-6080-5998 First feelings are: flesh, vocals are nicely present...

Hello guys,    Just got   2x MATCHED 6080 Sylvania USA Double Triode Power PAIR Tubes E6080 6520 CV2984 and  MATCHED DUO PAIR of FOTON Soviet Military <> 6N8S TUBES 1962 made STRONG 6SN7  from a bulgarian seller for a reasonable price; very favorable feeling on my hd800 for the moment, some...

Alsace is a long time land of good beer makers, so we will have to be careful of where we put our glasses

OK, I have to be patient about future comparisons... In the next weeks/months a comparison with some tube-amps from HCFR members will be organized at my home; I will evidently post the results in this thread.

Thanks Shaffer for your impressions vs your Krell and your future ones vs the WA6! 

I feel missing comparisons with other tube-amps of same price/technology in this thread becoming very tube rolling oriented... Am I alone?

nephilim, did you test some anax mods variations on your hd800?
