I have finally finished installing the Danny designed upgrades to one of my two Lintons. I took the opportunity to A/B listen test the unmodified and Danny upgraded version in mono. Okay - so they are certainly not the same speakers. To be clear, the originals did not have the sound signature I enjoy (too laid back, midrange clarity was less than what I like, etc), thus why I went the upgrade path. The Danny designed version sounds much more upfront (not in your face) and the midrange clarity is astounding and the bass remains tight with (maybe) more extension. To my ears, the changes made by Danny in the frequency response are responsible for many of the positive (to me) changes. However, this upgrade has convinced me of the value of the parts quality! Listening over and over again to the same song on both speakers (alternating) was enough to 'sell' me. The major differences were in the treble and midrange - listening to Lumineers "Dead Sea", I could hear the separation of instruments, voices, and notes on individual instruments. Further, the lead singers voice can sometimes be a bit fatiguing over the unmodified Lintons, but this was gone with the modified one. Technical details - I used all the supplied upgrade parts except the tube connectors and no rez. I did not use the tube connectors because I did not wish to modify the cabinet. I did not use no Rez b/c the box is separated by the midrange tube (cabinet within cabinet) and the new crossover parts take up a lot of space, so I felt there was insufficient space left. So, instead I used roof membrane (rubberized asphalt adhesive backed by layer of high density cross laminated polyethylene) throughout the cabinet and then installed the crossover components on top. Other equipment: Benchmark pre-amp and dac, Schitt Aegir mono amp.
