Digital amplifier power has never been more compact and affordable: With a size of just 190 x 35 x 102 mm, the three new ESX QUANTUM QM miniature power plants are convincing all along the line. The QM amps offer state-of-the-art technology in a very small space and are all solidly constructed. All three amps are based on the somewhat larger sibling models of the ESX QUANTUM QL series, only a bit more compact and much easier to install. Thanks to the high level inputs including EPS and the automatic turn-on function, they are also perfectly suited for integration in factory sound systems. Each model is also equipped with a compact bass level remote control.

Perfect Adaptation of Lovecraft's Story
Format: Kindle
Gou Tanabe has been making probably the best manga/comic adaptations of Lovecraft's works recently, and this depiction of "The Shadow Over Innsmouth" is by far the best.
Tanabe really captures visually what Lovecraft was conveying via the text of the original story. Innsmouth is decrepit and rotting, the locals are sinister, and the deep ones are hideous. And, as always, Tanabe's art is of the highest quality.
I can't recommend this enough, and I eagerly await whatever adaptation he does next.

Gou has done it again.
Format: Paperback
I like the original text, I love the adaptation because it doesn't stray too far from it. The illustration is beautiful and sometimes gross (In a good way, I mean it's a cosmic horror about people turning into fish, maybe don't read it right before a meal or before bed.)
Gou Tanabe has been working through many of H.P Lovecraft's more popular or interesting stories and this one is just about as good as the rest. The translation as always is very good throughout with only one or two "Wait, what?" moments which could have come from reading the original text differently.
I definitely recommend this book and several of others from Gou Tanabe if you love cosmic horror, manga, or H.P Lovecraft.

An Eldritch Tale Deserving the Manga Treatment
Format: Paperback
One of Lovecraft's very best (and my personal favourite of his macabre tales), rendered in grotesque mana style. While it doesn't eclipse its inspiration, I thoroughly enjoyed this unique take on a classic tale.
