Hello Joe, Thank you for the kind words. I appreciate them and am glad you are finding something of value in this thread.
I have been reading about your system and amplifier auditions. I envy your idea of building a dedicated room. My advice there is just not to make it an isolated cave but rather a welcoming space for others to enjoy your system with your. Ultimately, that is more satisfying. I had two pairs of Magico speakers and continue to read about your system with interest. There is a lot to address in your post, but I will try to get to the heart of the matter, as I see it.
I am not saying that everyone, or even anyone has to remove name brand power cords and room treatments to achieve natural sound. I am saying that doing those things made my Sublime Sound (Magico Q3/Pass) system sound more natural. You can read about my two years of experimenting with set up in my thread about that system. Speaker orientation also had a profound effect. Removing audiophile acoustic treatments does not mean that my living room suddenly became untreated. The furniture, rug, blinds, all act as room treatment and effect the sound. Boston Symphony Hall and the Vienna Opera House do not have acoustic panels hanging all over them like some other more modern halls. Acoustic treatments alter the sound. I think people should experiment and decide what works best for their rooms and their tastes.
The power cords and steel plates also have very specific effects on the sound. They require experimentation too. The idea behind natural sound is that there exists the specific target of live acoustic sound and it is the reference against which all decisions about a system and its set up are based. That live sound is natural, and anything one does regarding his system either gets him closer or further from that target.
My Micro Seiki turntable sounds natural. The American Sound table sounds more natural. They have a similar flavor. The Thorens Reference turntable that I heard at David's house, has a different flavor, but it still sounds natural. This has to do with degree of resolution and how it is presented. Boston and Vienna sound different, as do other venues. People may prefer one to the others. We hear live instruments in these places, and we instantly know they are live. It is because they sound natural. If something does not sound natural, something is wrong.
True venue sound does not depend on using audiophile acoustic treatments, fancy power cords, or isolation products. It depends on gear choice and system set up. Good electricity delivery helps as a foundation to good sound. There are different degrees and levels of success, but if it resembles the real thing, and is convincing and believable, and ultimately creates the experience of listening to live music, it is natural sound. For more detail about this, you could read the set up experiments described in the last eighteen months of so of my Sublime Sound thread to the beginning of this Natural Sound thread.
