My first night listening sesh with the mjolnir 2. Kicking some ass with my HD600s. Makes me question the need for an OTL, at all.

Thanks. I've had my time rolling 12au7 and I honestly don't like them. Maybe some day again. I'm going one at a time here and placed an order from Brent Jesse for some amperex "A" frames. I've been listening to the MJ2 with my HD600s tonight with some nos 6dj8 "ram" tubes from Yugoslavia. They...

Nice, those are the ones I ordered, the Amperex holland "A" frames from Brent Jesse

My first high-end amp from schiit, really awesome! I had no idea this thing was built so well, really like the wrap around aluminum body. Could I ask for some tube recommendations? I already own a tube amp that is pretty neutral and smooth, so I would love something with grit and warmth but not...

thanks! My impressions are limited so far but I would say it would be overall speed and soundstage got turned up to eleven. The stock sound with all the old parts was good but with a noticeable veil of muddiness in the whole stage. The tone and timbre was great but the upper mid range was...

Final update. Finished! She sounds really nice 👍 New parts: Schaffner IEC/emi filter combo socket Nichicon UPW 2200uf x6 Rubycon ZLG 56uf x9 Vishay wirewond resistor 47ohm 5W All linear regulators replaced, LM317/337 replaced with LT317/337AT Power to DAC board umbilical cable Panasonic...

Just finished rebuilding the Adcom GDA-700. Really special, pretty stoked to continue listening. See thread here for parts list and more photos: https://www.head-fi.org/threads/adcom-gda-700-dac-updating-to-modern-parts-advice.972731/post-18130510

Yeah it's really interesting the HDCD filter. Some people say it really sucks but I have seen a couple say that it's all in the power supply. Problem is that replacements are non existent for either the HDCD chip or the ultra analog aes chip. Upgrading them would be not worth it especially if...

Thanks! Yeah I had mine in my system for a few hours and it sounded really close to my other DAC which is twice the price. I went with Panasonic eca-m caps for the entire DAC board. The lead spacing on the board is 2mm and I'm not comfortable stacking caps in all directions to make larger caps...

Progress, power supply board desoldered and flux cleaned I now have all the parts and the soldering will commence!

I think you will really like it. Just remember that it is going to need at least 400 hours burn in, not including it's factory burn in. I bought mine in September and used it for a few hours every day. It didn't start to sound correct through the frequencies until January. My speakers sound like...

Yeah it seems like it could be worth it. Problem is that the results would probably be minimal for the effort. There are a crap ton of already compatible tubes for the MJ2. I think I'm much better off just experimenting with those.

Just bought a MJ2 and already digging around for mods I could do. I came across the 5687 tube variety. Same 9 pin mini design as 6922 but pins 6-9 are swapped around so a converter is required. Only problem is that in order to run in 6.3V, pins 4 and 5 need to be tied together between pin 8...

To make a tiny comparison, take the Schiit Rag 2 for example. Similar to the Master 9p in that its a headphone amp/preamp/speaker amp. Schiit has said that The Rag 2 is more of a speaker amp first than a headamp, so there is a good chance that the Master 9p is in the same boat. I would put...

Taking it out of the box, turning it on for a photo, confirming its operation; all things that will only help you sell it. New in box means very little especially with no branding. As far as anyone knows, this is a $2400 moving box. I'm not quite sure how someone hasn't taken this listing...

Pseudo tube hybrid sound from that then! Very cool. If I recall, some people said that the Mentor needs like 200 hours to break in. I would have one already if it only had pre outs.

Don't sleep on anything from Audio-GD. For R2R, their R-1 NOS is far and away better than any chip based DAC under $1000 or even $2000. For the amp, my understanding is that the Atrium is on the warm side, so SS could be better for you if you don't want any more warmth. R2R DAC + SS easily leans...

Thanks, I almost forgot that I need these to roll amps. I ordered 6 new OPA828s in SOIC to DIP8 adapters from brown dog as well

Yesterday I received a great condition Adcom GDA-700 DAC. My first experience with the PCM1702 chip, I like it! I have a Audio-GD R-1 NOS already and while it is pretty amazing, I've never felt like I completely vibed with it, mainly because the sound stage is so very in my face all the time...

Is there merit to my concern of there being different types of relays used for the volume control, black vs white relays? Me personally I'm staying away from this new model. The front panel looks way to congested. Plus I'm a fan of the master 19's symmetry. The similarities between the new...
