The thread were I did the review was noted earlier (and again it is here
However, there is a person who might chime in here who has a modded LSA and before that had my modded IceEdge amp which has no roll off using lower impedances). For the guys who insist that measurement is everything, the first thing you should know that my hearing has been tested by an audiologist and I had an appointment with my ENT a couple of months back and I asked if he wanted me to repeat the hearing test I had the year before and he said no my hearing was wonderful.
My friend who was over also has excellent hearing. Besides the listed playlist in the review, we listened to tons of things, some of which be indicative of deficiencies in upper frequencies (and the tonality was just better and more realistic, including the below as well as a couple that what whathifi lists as the 10 best tracks to test treble and notes "Coarse or rough treble doesn't always reveal itself straight away, and it might be a while before you realise what's missing when that upper register is overly rolled off, so it's worth taking some time to focus on precisely what's happening up there" and the 3.7 measurements are listed in a Stereophile review) Is the LSA the best sounding amp in the world - of course not - but the question should be what does the competition sell and how does it compare and I've owned a couple of Class A /A/B amps around the $9k range which were not as good to me or others who heard the actual system and of course those observations are limited to those specific amps - and that is what the thread is supposed to be about - how the amp sounds in the real world with real speakers in a real system). My advice to anyone is buy what you like and listen to it and don't worry about anything else.
