I can't recommend the Reus system more highly. I had the stage 3 system installed about a year ago. At the time when Cliff did the installation he told me I'be entitled to forthcoming upgrades at no charge. A few weeks ago when he was on his East Coast installation swing he came to my office parking garage to do the latest upgrade. He spent about two hours on the upgrade.
The results were astounding -- the upgrade took an excellent system to an even higher level. In fact, it was like he installed a whole new system. Everything about the system is better. The sound stage is improved, the bass crisper and with an even wider range, and the highs more clear and crisp. Every bit of music I play sounds noticeably better.
SUPRKAR also had the upgrade done to his system. He and I talked a few days ago and he agrees that it's like having a whole new system. I'm not quite sure what Cliff actually did to the system but in my book it was magic.
Being devoted to classical music, the real test of any system for me is the sustained double low C on the double basses, contrabassoon and pipe organ in the "Sunrise" opening to Richard Strauss's Thus Spoke Zarathustra (made famous as the theme for Stanley Kubrick's 2001 A Space Odyssey). Most systems cannot produce that sound at all -- let alone well. Before the upgrade, even the Reus system produced an anemic double low C. With the upgrade the sound is incredible -- the whole car shakes and the bass is quite clear, not to say the many rich sounds in this great tone poem.
On the flip side, tracks of Junior Wells, another favorite of mine, are have now gone from merely great to incredible. As he wails along it sounds like his harmonica is in the car with you.
I couldn't be happier with the system and the great service provided by Reus and Cliff Johnson.
