Hi, as I write I am listening to my 30S preamp with the new SHHA 2 upgrade. It just came back today - not even broken in. WOW! I loveded my preamp before but everything is better. Specfically, the bass is more defined and powerful, Complex passages don't congest and sound stage is huge. Take everything you like about Spectral products and increase that 3 times. Without a doubt worth the $. Spectral had my unit only 10 days. Thank you Spectral and Thank you Terry Menacker of Overture Audio.
