I am rolling on the floor here. :cool: .... and that's why you're not an audiophile, Grasshopper... :) That said -- you should see the things folks do with those hyper-cheap Asian "tube preamps". :eek::cool::facepalm...

Do these operate at lower voltage in a starved plate configuration? Those don't seem like a good idea to me.

Well, entertainment purposes is exactly down my alley. This is supposed to be a fun project and nothing to be taken too seriously... A bit like applying pineapple to pizza... ;-)

I have this small tube preamp (mine is antother brand and with tone controls) https://audiokarma.org/forums/index.php?threads/fx-audio-6j1-tube-preamp-a-31-wonder.848535/ + a Definitive Technology DN8 subwoofer using splitters. My problem is that the sub have aut on off as long as you have...

I gave a test on this thing. There is a big thread on this subject --> "fx audio 6j1" on audiokarma where you can learn a lot (idk if i have the right to put a link or name of another site so tell me if that's a problem and i remove it). I don't remember correctly everything but there is a phase...

The Treachery of Reviews. :cool: It's not an objective review, but it's the preamble to a review in terms of use and listening impressions, which is fine! Some of us are interested in vacuum tubes for audio reproduction -- although, for some of these mysterious and inexpensive little boxes...

Except exchanging the amp or the sub for models which suppress pops there is nothing you can do. (Mine Denon X3700 and KEF92 subs don’t pop).

The rule of thumb with most tube gear that lacks output DC protection - which is literally most tube preamps with a capacitor coupled output (very common): 1. Turn the amp (sub) on ONLY AFTER the tube preamp has been on for a minute or so. 2. Turn the amp (sub) off BEFORE you turn off the...

Well... I mean... depending upon one's goals... there are inexpensive and effective :) little tube distorto-boxes. Two of the current darlings being: https://audiokarma.org/forums/index.php?threads/fx-audio-6j1-tube-preamp-a-31-wonder.848535 ... and now a variant using directly heated...

That's true you have to change the red & white cables going into the amp and I changed the input and output coupling from 1uF to 4.7 on https://farmedia.com/tube-audio-line-level-buffers/ 'Rolled off bass response – output coupling capacitor too small? – (yes, 4.7uF looks about right for the...

I bought the Topping L30 II, for use as a preamp and therefore to be able to benefit from a power gain. I have a John Linsley-Hood 1969 Class A Amplifier aka Nobsound NS-02g of only 2x15 Watts, but a pair of Magnat Quantum 757 with an efficiency of 93 dB. Also SMSL SU-8 V2 as DAC. To obtain...

The tubes are these in the photo, I don't know if they are authentic or not. I assume they are used in the preamp circuit. The amplifier chip is, as I wrote above, the Infineon MA12070. I confirm that the bright neon sign can actually be removed (you can also see it in the photos of the first post)

You may well be right. Time to go sleuthing! ... or... someone has to buy one. ;) It ain't a-gonna be me, because I've already experienced a one of these little boxes*, albeit of a slightly different recipe. This is the one that's been the subject of [EDIT] a 220-page page thread @ audiokarma...

Too bad that thread cant stay on track for more than a few posts......

Yup. Just the thing for a $99 tube "buffer" -- which is, in fact, not a proper buffer at all... but rather a distortion (effects) box. :cool: Speaking of misues of tubes -- one of my personal favorites, FWIW. At least it is cheap. :rolleyes...

Ah, upsampling is possibly why you are getting good results via HDMI. But there are surely applications on your laptop which will output 44.1kHz sources at (native) 44.1 kHz output - in fact I see in your photo in post #71 the D90 displays "44.1kHz" though, in that particular situation I see you...
