listen xiang sheng dac, I liked their sound. much better than imac dac. but T1 is ugly sound. that's what surprises me
Maybe you hate tubes and like a more clinical sound?

The Xiang Sheng looks interesting. I have no idea why a manufacturer would put the tube inside their equipment like that... right close to the PCB and components. That looks like a disaster waiting to happen...

 

andresa - did you try changing valves in the T1? Did you find anything you liked better than the Mac with different valves? Highs, lows, mid-range, soundstage? Or does the Mac just sound completely better, even with other valves?

 

I will plug into my girlfriends laptop later and see how it sounds feeding the WA2, compared to the T1, and also the Modi.

Works for the Schiit Vali:

 

 

Though, I can't wait to hear your findings on your girlfriend's laptop vs T1 vs modi :smile:.

The stock 6N11 really sounds a big 'meh', but 7308 should be good. Haven't tried one myself, but haven't seen a single bad review on them (7308).

 

You could try what I tried, installing an RFI filter in between the power strip and the T1's PSU power plug. This upgraded the sound by quite a bit for me. In my specific case, what I thought to be 'already optimized performance', turned out it's not. The T1 really benefits from an RFI filter in my case. It's only $3-$10 (mine was $3)

I have Amperex usn-cep 7308 gold pin made in usa and 6N11 (tube stock T1), always my imac sounds better. not a sound profile. T1 dac has less quality.

I remember some months back a guy had the same issue with his Aune T1 + Macbook pairing. He claims the Macbook sounds better than the Aune T1 DAC. I guess there's probably some truths to it, people have different preferences in sounds and they might actually be more resolving than the T1. But then again I cannot comment since I've never compared them side by side, and my memory is pretty bad.

I thought my laptop sounded better than the HRT Microstreamer which had glowing reviews. I think that had to do with power and properly driving my headphones though. The HRT didn't sound bad, just everything that I thought was wowing me would also be there with the stock laptop. It had a decent hi-def onboard soundcard that could do 24/192, but the Aune really sounds a lot better.

Still waiting to try the Mac today in a bit.

edit:

Andresa I would love to see a picture of the tube you're using.


Just compared the Mac to my T1 and there is no comparison. Playing a vinyl 24/92 rip of Stan Getz & Charlie Byrd - Samba Triste

At first I tried the Mac and thought, wow, this sounds very good. Nice definition, very crisp, the presentation is well defined... bass, treble all present. The bass/lower midrange definition is a bit blurry to me, but the top end is very crisp, and the bass notes are present. The bass and midrange aren't thin sounding, and the treble is crisp. A nice presentation... has a decent amount of height, and soundstaging sounds about average. (Better than the soundstage on the Chinese tube with the T1 for sure).

On to the T1. Immediately, the tone sounds much more realistic. The top end was the immediate improvement that I heard. Also the soundstaging... the width is huge. Much, much bigger than the Mac. Bass is also better... it's more rich and still tight. Back to the highs, I hear reverb on the drumkit, where the stick is rim-shotting the snare. I also hear more air coming from the reed of the saxaphone that Stan Getz is playing. Wow, the guitar is way, way, way over in my right ear, and his saxaphone is starting on the far left, with the decay pushing into the right ear occasionally. The bass is pushed even further left, behind Stan. The tonality is the biggest improvement though... this sounds rich, lush, and refined. The actual vinyl on my rig has far more pops, hisses, and crackles, but does sound a bit more "wet/smooth/atmospheric" - this still sounds very organic though, and I love the ease of double clicking instead of loading the record.

Back to the Mac - let's see what may sound better... Alright, so what I take from the Mac is a crisper, flatter sound. Less fleshed out tonality, and more of just a generally crisp, perhaps refined sounding presentation. Polite maybe? The bass, and drums really don't shine the way they did with the T1 and I'm sad about that. The guitar sounds nice, elegant... and the sax is pushed over to the left side, but I can barely make out the bass. It sounds muddy to me. Less rich and tight. Also where'd my wonderful sounding snare reverb go? It's gone... I'm left with a tinny sound.

Andresa which headphones were you using? Something with low impedance? I found the HE-500's didn't sound very good with my T1, and I was met with a lot of criticism for posting about that here, but I honestly couldn't hear highs and the midrange properly with the HE-500's + T1 when I was using mine. I think maybe you have low impedance phones and the 10 ohms output of the T1 (or maybe more) is screwing with the presentation. Also, I'd like to see a picture of the tube... there have been fakes in the past.

This video captures some of the smoothness I hear on the sax with the record... a lot of the song is killed by the encoding on the video, and the soundstage is super narrow, but his record player fleshes out the bass/guitar the way the T1 does, even listening just through the Mac.

Hey, another thing I'd like to point out is that the differences between gear can depend a LOT on volume. If you listen at a low volume, that could be a factor.
post #6974 of 8013
I've found that most people can agree on what sounds 'better'. Most people just don't care as much as we do lol. My vote's on there's a problem somewhere in the chain, but who knows?

After not listening to my Aune T1 MK1 with Amperex 7308 for awhile, it is really really nice to listen to a tube-based music again. I'm using it with my Xiaomi Piston 2 IEM.
