Audiophile tube warmth

The Tube Box S3 B is a audiophile phono preamplifier that brings true analog warmth to your vinyl playback. It features a fully symmetrical and discrete gain stage, balanced 5-pin mini XLR input, and balanced XLR outputs. Adjust settings easily from the front panel, and enjoy clean, interference-free performance thanks to its robust aluminium chassis. Available in silver or black and made in Europe, the Tube Box S3 B is a compact yet powerful upgrade for any serious vinyl setup.

"B" stands for balanced

The symmetrical design is the real standout feature! Connect your turntable with the 5-pin mini XLR cable & profit of the balanced signal path. Symmetrical, or also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A true balanced gain stage can now extract the final musical information out of the +/- signals and subtract, remove, all noise that could potentially be added along the transmission. As there are two separate signal chains, we also needed two individual amplifier sections. Definitely unseen in this price range & the best and cleanest amplifier for your phono signal!

One of the greatest books I’ve ever read
Format: Audiobook
I wish I could have met this man. I began having OBE’s about 8 years before I read the journeys trilogy. When he talked about the out of body simulations my head nearly popped off. I’ve had a few of those and never found them described in detail anywhere else. This is the greatest book and most profound trilogy on personal spiritual exploration and out of body travel ever written. Period. Such a gem and so incredible to be experienced outside the traditional contexts of yoga and meditation. A true original work. Thank you Bob. These 3 books changed my life and made me finally enquire “what is under the hood” in an OBE. What transports the astral body or consciousness from one dimension to another?

This is a must-read for all those who are seeking answers.
Format: Paperback
If you can read only one of Robert Monroe's 3 books ("Journeys Out of the Body," "Far Journeys" and "Ultimate Journey"), "Ultimate Journey" is the one to read. Monroe's books chronicle his amazing learning experiences as his ability to travel out of the body develops and his capability to remember and to put these odysseys into words increases. Without laboring over material covered in the first two books, Monroe sums up his earlier adventures and then writes about his most recent and significant discoveries on this, his spiritual journey to understanding. If you have ever wondered if there is a God, why the Bible says that God is Love and in another place, shows God to be a vengeful being who orders the killing of many people, "Ultimate Journey" and the lessons taught to Monroe in his out-of-body state will help to clear up these questions. To say that "Ultimate Journey" will give you a whole new perspective on life, death and what lies beyond is an understatement. This is a must-read for those who are seeking answers! And, if at all possible, read all 3 books in order. "Far Journeys" is definately the most difficult to read, since much of it reflects Monroe's efforts to translate non-verbal communications from non-humans into English. But the information in that book is voluminous and well worth the effort to read it. Happy reading, fellow seekers!

YOU can actually LEARN to do this!
Format: Paperback
"Eavesdropping on Animals” by George Bumann really was a welcome break for me as I spend so much time outside in Nature. George is also amazing at being able to read Nature in a way I had never seen before. His insight via really listening & paying attention to everything around him, is so precise - he can literally know where animals are without seeing them. I got this book mainly because HE wrote it & I knew it would be interesting. The thing that surprised me was he actually teaches you how to do what he does (ie: know exactly where a wolf pack is traveling by hearing a certain coyote call & knowing the terrain). I started simply by really paying attention to all of the bird songs going on outside my window very early each morning & could finally hear ones that were repetitively there & was able to figure out what they meant by getting outside & sitting on my patio as I drank my tea. If you LOVE NATURE, you would so get into this book. It’s a great teaching guide, plus his stories are so cool! Entertaining & informative to read.

Will forever change your experiences in nature!
Format: Hardcover
I am an instructor in animal language in the wildlife ecology department at two leading universities and I can attest that George is an expert animal whisperer/linguist. I've had the pleasure of knowing him and hearing his stories, and this book is an outstanding gateway into understanding the behavior of animals. It will reveal a whole new world to you every time you step outside, whether you live in an urban area or next to a wilderness.
