hey guys from Australia (bigsby and stainless,etc) could you pls confirm the volt of your psu is set to 220v ( i mean the switch is set to the position where it shows "220v") ?
SO glad there are more of you with WA7's now! Not so glad to hear about these two issues, but at least they are relatively isolated.
The only issue i HAD (now resolved) was i messed with the midi settings, clicking back n forth fast through them all to try to hear differences, and the DAC got angry. It went digitalised on the low end. Since then, (although I think its like this out of the box) ive discovered i dont get ANY sound out of the unit when i first plug it in- unless i reset the HZ setting to 42000 in the midi settings menu, then go back to 192000 and it runs perfectly. Again, i think it was always like this and could also well be my ancient MBP or file type.
I more likely suspect this is a firmware thing, and only a minor issue that doesnt bother me at all. Now that i know what it is, its just part of my process when turning on the unit. Im guessing there will be a download to fix these issues in the future. the actual amp/dac itself and all hardware and manufacturing are perfect for me! No heat issues (runs quite cool actually), no issues at all really.
Being a gen 1 product there was bound to be some anomalies occurring. The great part about WOO Audio is their stellar reputation for addressing these issues and resolving them with good customer service.
This is good advice to start with.
I myself am going to also take some of the other suggestions here and buy myself an infrared thermo just to have at home for other reviews etc, i have a lot more gear coming more regularly now.
Carsany: are you running MAC? you may need an OS update to fix the issue, or a simple restart and check those midi settings. Most DAC issues like that are often the computer. If this doesnt fix it try it on another MAC that runs the minimum OS requirement +, failing that you can email Jack regarding a software update.
Thanks for all the good info. I'm running a iMac with all the latest updates so doubt there is a issue there. I'll do a little testing on my MBP retina that is clean software wise and see if the issue arises. It's no big deal so far, seems to only happen in the beginning of a listening session. After the first 30 minutes or so, I went 2 hours with no issues. The WA7 was left on for 3 hours before I even started, so it was warmed up. Seems the data has to pump thru it for a while before it all starts running smoothly. It happened with the sovtek and EH tubes, so no affect there. Thanks again for sharing your experiences.
Im still not convinced this temp thing is a serious problem. I was reminded of the Valhalla today, after only 40 mins on that thing it was like an absolute OVEN. I remembered my recent thread, where i auditioned a bunch of tube amps at A2A when heading down to buy the Pan Am. Thread can be found here. I rang Mark today to check. His a guy I met recently through work who owns a Valhalla and is a diehard fan. Ive listened to his amp recently and asked again (since noticing the extreme heat the first time) how hot it gets. He said again, as he had the time before: "Hot enough to cook your breakfast man, but still sounds good and never had a problem in the year or so ive had it".
I found i was SHOCKED by the heat of the Valhalla there too, so it couldnt have been an anomaly on Marks end or the demo at A2A either. Obviously its better if gear runs cooler, but we are talking tubes here- they get hot! My bassman guitar amp, or any of my other vintage moody tube amps etc, all get HOT- i mean H>O>T, but its just a given for vintage tube amps (guitar ones anyway). Perhaps the temps on the WA7 are ok? Im going to run mine for a few more hours tonight and get back to you. If i cant, try as i might, replicate your temps ill concede.
Ive already emailed Jack this morning to comment when he has the time on temps. In the meantime, im going to "suffer" through hours upon hours of music and movies and frequent checking amp and psu temps.
yep mines set to 220
ok had time to try out the HD650 and Q701 as well as the stock tubes
i found the stock tubes to do well with the HD650, but gold pins all the way, that said, the HD650 and Q701 don't come close to my Signature Pros.
My last test was seeing what my SigPro's were like with the Dragonfly vs Fireflies(gold pins), as i suspected the WA7 had more soundstage and weight.
So thats my final setup, WA7(EH GoldPin) + SigPro = win.
