Thanks, I have the T1 with the HD558. They are great together. I want my next step to be the 600 but won't be able to "upgrade" from the Aune for a while.

That's a nice next step. The 600 sounds pretty nice with the 7308 tube. And like the rest of us "hobbyists", you can then save for the next upgrade. Check out that Bottlehead Crack for the real bargain for your 600's.

 

Somebody's yelling "Get out while you can!"

So, my Aune has been doing some hiccups.  It is playing beautifully and then, suddenly, it hits something and does a little hiccup.  It is short (maybe 0.1 seconds) but very obvious.  I'd say I get one every 10/15 minutes.

 

I am using Foobar with WSAPI.  I took off my USB and reduced bit depth to 16.  This had no effect.  The hiccups are still there.

 

Any suggestions?

Have you seen these solutions?

 

This one assumes windows is the problem:

This one assumes usb is the problem:

Thanks so much for the useful response, crtlshift!!

 

I took a thorough look at it.  I implemented everything that made sense in my system... or used an approximation, e.g. my BIOS has not an option to disable the original sound card.  So, I disabled it in the OS (Windows 7).

 

Additionally, I gave foobar WASAPI bigger buffers.  Properties >> Advances >> Playback >> WASAPI:

  - push mode: 500 ms

  - event mode: 100 ms

  - high worker process priority: on

 

Now, everything appears to be copasetic.  :dt880smile:

 

One thing I am curious is whether I should change from WASPI to ASIO.  But, as my system is happy now... I leave this exploration to some other time.  :L3000:

I loved my HD558's for a very long time. Had a difficult time adjusting to HD650's, but now I'd have an even tougher time adjusting back to HD558's. Love the mids and detailed presentation of the 558's. They are also extremely comfy. Glad you're enjoying them with the T1... I would also bet that warm Siemens tube would be heaven with the 558s.

Will Meier Corda Rock work well with Aune T1? I don't know how good T1 amplifier section is, will Corda Rock make differences?

Anyone tried Corda Rock and T1 yet? Meier did some discount on them, and I'm interested.

I don't know if the amp section or EH6922 which color the sound bright, and actually I prefer something more neutral or warmer.

 

Still waiting for my Philips PCC189, HP ECC88 (Amperex made, I think) and Philips ECC88. Can't find decent priced Amperex OG without having to bid on ebay because I'm unable to checking ebay pages frequently. And also, too much hassle to import things into my country, usually I had to ask my friend who currently in German to hand carry them.

My unit has now developed an issue related to the Line Input. As far as I know this has nothing to do with the valve as that is only for the DAC section.

 

It is way over-amped, and the result is serious distortion across the entire frequency spectrum. I've tested it with my cassette and minidisc player with the same results, so I know it's nothing to do with the source. On another note, even if I unplug the PSU I still get an output (albeit much quieter) with the same distortion, I wonder if there's a static build-up in the circuitry.

 

I get no such issues with use as a DAC/Amp.

The amp portion is bright. I think someone took theirs apart and find that the design was basically a cmoy amp.

I'm considering picking this unit up but I'm unsure if it would help me out in my situation.  

 

I'm hoping to use the device as a DAC + Preamp into an amp.  I have a PC with Jriver that I use to send music over toslink into an Onkyo 9050 with an integrated DAC - the amp drives two Klipsch RF52s.  

 

My goal is to get a tube sound without having to invest tons of cash into a full fledged tube amp.  Do you guys think I would see a benefit in running the RCAs out of the Atune into my amp?  Hopefully I'm not bringing up previously put to bed issues but there is a lot of info in the 350 pages on this device!

I used for this application and I am very happy with it, darkstargtk.  I have a Peachtree Nova which contains a DAC, but I prefer the Aune T1 DAC.

 

IMHO, the Aune DAC is much better than its headphone amp.  The tube you use do matter a lot, though.

 

BTW, don't use the Aune as DAC + preamp.  This requires you to take the output of its amp.  Use it only as DAC, doing the volume on you Onkyo.

After reading back a couple hundred pages, I have decided to investigate which capacitors came inside my T1. (There were quite a few posts about people opening their units up and finding a variety of different caps, some good and a lot that weren't so good).

 

I opened it up this morning and this is what I found:

 

Headphone amp board coupling caps = ELNA (M) (brown) 47uF 50V (I have no idea what kind of ELNA caps these are...)

Headphone amp board rail voltage caps = Nichicon VR (M) 470uF 25V

Secondary power supply caps = Purple (Panasonic?) 962TN 330uF 35V

Main power supply caps = Nichicon HE (M) 3300uF 25V

 

Pretty sure these are different cap combinations than the ones posted by users previously in the thread, so I guess maybe every T1 is unique :P

 

After reading CoiL's posts, I plan on upgrading these to ELNA Silmic II's, and also upgrading the main PS caps to Panasonic FR's. I ordered them up today from a vendor (with a spare of each as well) for around $20, so not too much cost. I plan on doing the soldering in the next couple weeks, so I'll post results later if anyone is interested. 

 

Seems to me to be a cheap way to perhaps get better sound out of this already great unit.

I realised the problem: I forgot to remove the phono preamp from the mix when I was changing inputs to non-phono sources. smily_headphones1.gif

Yes, I looked back several pages and found the post you mentioned. Meier Corda Rock for 160 Euro is pretty sweet, no?! So... New PC or New Amplifier? Ugh, my wallet...

Now you make my hand itch to open my unit. The thing is I'm not sure I can put it all back together, I'm so klutz LOL

Aune had announced an upgrade to its T1. The new model is T1 MK2. New upgrades include support up to 24/192kHz and non-synchronous USB input.

Isn't Aune T1 Pro an upgrade to T1 MK2?

post #5235 of 6215
There is no T1 Pro. There's an X1 Pro tho.
