In my particular case, no, it hasn't changed.

Funny that the dealer says that whining is normal. The guys at Pathos said it's the first time that they hear about such noise.

  Oops, didn't see your post until I got a notification of williamd's post. It is audible at all volume levels and when all inputs are plugged off. It definitely comes from the amp itself.      Yes it is. Do you get the same whining with your Aurium?

I kinda agree with borrego. A high output impedance does something with the T1 that makes the bass more enjoyable. The Bottlehead Crack and Woo WA2 give it a little more ... buzz/volume (I have no better word for it). Beyerdynamic amps also do that with the T1 and it happens that they all have a...

  Well, I don't have the old T1 anymore, I've sold it a month ago, so take my impressions with a handful of salt. But essentially, the new T1 is just like the old T1. It maintains the same bright/brilliant-ish signature with an emphasized treble section. Don't expect the harshness to be gone...

Give it some time. I felt the same about the bass performance of the new T1. But even the old T1 performs better than that. So I'm quite sure that it'll improvesignificantly  after some break in.  I feel different about the harshness. The new T1 manages to sound more less harsh. Songs that I...

  iFi has been growing in popularity the last couple of years. They're supposed to offer very good value for the money. Like FiiO, just one step higher in price.        Crossfeed is nice but subtle. Try it out with Fidelia (Mac) or JRiverMC (Windows) and see whether you think it is worth...

The hissing is always there and loud. I've rolled so many pairs and even the 6N23P-EV won't silence it. I only found that some noisy tubes just make it worse. So it's likely not the tubes. But I also get a high-pitched tinnitus-like whistling on one channel. It persists regardless of tubes and...

  Tonally, they are a revelation. If you ever felt that tone color is missing in your DAC's sound, that's the typical delta sigma sound. To give an analogy, R2R is to Delta Sigma like tube amps to solid state amps. Tonally richer, often lusher/warmer, sometimes too smooth for some tastes...

  I wouldn't know there are any. It ultimately depends on your preferences though. Maybe you prefer warmth after all...       Are we talking about the same tube? They are becoming scarce but their price is still low, like $50 a pair. Lots are cheaper, ten tubes can be had for $50 (most...

  By crisp I mean extended treble. From your first post, I assumed you don't like it rolled-off. It will not sound aggressive or forward – probably. The only way to know whether you like it is by trying out. The Philips ecc88/e88cc is a good start. If you don't like it, try a different flavor. ...

  Most important thing to keep in mind: don't spend more for tubes than for the amp     As StanT said, trying out various driver tubes is the only way to know. If you prefer crisp highs, the Philips ecc88 or e88cc might be a better choice than the e188cc because the latter tends to sound...

You could also try the Ei EZ80, which might be easier to obtain.

Yes it is ugly, but it is just what the target group will want. For most of us, this post-Orpheus is just a monument stating "Sennheiser makes THE headphone, and no other cheap *** company".  But it's not aimed at the common people. This is something for Arabian princes, Russian oligarchs...

  They're not sold on the retail market. I think you're supposed to purchase them at your local distributor. In your case, that's Paxt (info@paxt.ae).
