I don't get any hum with the HD6XXs, but I do with the TH-X00 on high gain. Stock tube.
Tubes can pick up noise from different sources. Cellphones, Wifi, etc. First step would be to make sure those type of things are well away from the amp. Of course using low gain should help lower the noise floor - although with 650 "clones"(?) you're probably better off with high gain.
The type/condition of the tube can also affect the type or amount of noise - some tubes just have noise.
Also, it seem that tubes are the only thing that people agree are improved by burn-in. The noise may go away after a few days of use
Hello dear Headphone experts,
2 years ago i bought myself a pair of used AKG Q701 and Soundblaster Z soundcard, over the last months i found out that the soundcard was limiting my headphones and so i started searching for a good DAC/AMP combo with a good bang for the buck.
Right now i narrowed it down to a Modi paired with a Vali 2. My question now is:
I have been reading a lot about how my headphones sound with the Vali 1 and the Vali 2. It seems like the Vali 1 would be the better match, as it warms up the headhphones quiet a bit more than the Vali 2 does.
So i thought about tube rolling the Vali 2.
I also put a bit of time into searching through some tubes and ended up with this one:
PCC88 / 7DJ8 NOS
Does anyone know if this fits my expectations? I am mainly listening to Electronic Musik (Techno, Drum´n´Bass, etc) but also enjoy myself some Indie or Alternative.
I want my AKGs to sound alive and enhance their bass a bit, as they seem a bit to neutral for me, when driven with my old soundcard.
Would gladly appreciate any tips or answers and hope i can finally by my first real set up.
Thanks already and hope my english is sufficient as I´m from Germany!
With kind regards,
Had no idea tubes could change how the sounds are, that's very interesting.
This is my first amplifier so I don't really have anything to compare it with, I believe the tube on mine is an Amperex Bugle Boy.
Going to look around to see what other tubes I can use with it, should probably do some research on this tube too haha.
I'm not personally familiar with that tube, but from looking around at other posts you lucked out again. There are plenty of tubes to look at. Go to the "Vali 2 tube rolling" thread to see what others are using and, of course, ask questions.
Thanks a lot!
Going to spend a bit of time time on that thread.
I didn't think interconnects would make that much of a difference. Evidently they do. I had been using a simple TRS Y connector at the output of an ifi nano BL:
Then switched to inexpensive discreet Monoprice Y connectors:
All-round better sound and imaging.
Some of the Monoprice stuff works well.
Wonderful thread from newbe head-fi listener here. Earlier today I uploaded to Thingiverse this Schiit Mini Stack mount for those with a 3D printer. Very solid and really helps them from not moving around. Enjoy.
Pssst, @Jason Stoddard ... @SchiitFerBrainz .... @Baldr . Would you consider selling such organisation-accessories for your stacks? It might reduce the frequency of boxes slipping off tables and shattering on the floor. It's like an Otter-box for smart-phones. Just my 2 cents...
I would buy one!
I just picked up a Vali 2 and a Modi to use at work. For the weekend I have them set up at home, and I just noticed that after I turned on the Vali, after 15 seconds or so, there's a lot pop in the headphones. I know that there's a delay in output while the tube warms up, but is the loud pop normal?
Yes it is. It depends on the sensitivity of the headphones and the tube used.
Yes, it's normal. So far, my headphones have been undamaged by the pop.
