all tube amps are not warm...
Agreed!
Many tube amps tend to emphasise the midrange relative to the frequency extremes. This balance suits the TH900 very well.
I had two pairs of TH900 modified by Lawton: one pair with a "warm" or "euphonic" wooden ear-cups and another with "analytical" wooden ear-cups (relative to the stock ear-cups). I left the third pair unchanged.
The "theory" says that the ear-cups are heavily damped acoustically so the type of wood should make no difference whatsoever. To my great surprise, the two modified pairs not only sound different from the stock pair, they also sound different from one another though they are identical in every way (same shape and size of the cups, same damping material, same upgrade cable...) except for the type of wood selected.
The biggest surprise of all was that I much prefer the pair with "analytical" wooden ear-cups! In comparing the three pairs, I discovered that the stock (unmodified) TH900 is pretty "euphonic" already. Just a modest improvement in transparency and articulation in the "analytical" pair bring the midrange and image into better focus and improve the sonic balance of this pair over the already wonderful stock headphones.
Thanks for the review. Now pass the corn :rolleyes:
