Lyra's are described by users as being Transparent and some might say are on the lean side of the scale.
The new TA might be less in the way and allowing this trait of the Cart's design to be perceived as an increased presence.
What does seem to be able to add to the 'Harsh' is the 6922's in the Chinook. When Tube Rolling using perfectly matched 6922's and E88CC's, there were 6922's used that could be described as 'nails on a Chalkboard' as a comparison to other Tubes used.
The TA, may have improved the Signal Sent, which in turn is enabling the Tubes to show of more of their own sonic offerings.
If the ideal is to lean further towards a Rich Tone on the scale, a SUT and Tube exchange might become the method to achieve this.
