R2R desktop DAC with JJ tube buffer
The WARMER R2R leans into tone. It’s a desktop R2R DAC with a tube buffer that adds body, color, and a relaxed kind of fullness that digital sometimes forgets. The fully-differential 24-bit resistor-array DAC sets the baseline with steady, unforced detail. Four JJ Electronic E88CC tubes bring a soft glow to the mids. Dual mechanical VU meters add a warm pulse to the room. With multiple digital and analog inputs, it works just as easily on a desk as it does in a living room system. When you want music to feel easy and inviting, this is a good way to get there.
Extensive connectivity
USB, optical, and coaxial inputs let you move between sources quickly. RCA and XLR outputs cover powered speakers, integrated amplifiers, and headphone amplifiers. Both outputs can run at the same time, which is handy if you enjoy switching between speakers and headphones during the day.
Fully-differential 24-bit R2R DAC
FIIO’s four-way fully-differential R2R design uses 192 thin-film resistors with 0.1% accuracy and low drift. It delivers the grounded, weighted presentation R2R fans look for. Instruments sit where they should. Details feel natural rather than etched. It’s a DAC that trades flash for ease.
Tube warmth with JJ Electronic E88CC valves
The tube buffer uses four JJ Electronic E88CC tubes fed by a ±28V high-voltage supply. JJ tubes are steady performers with a long service life, and here they bring a rounded, organic character to the signal. Edges soften. Vocals pick up a little more texture. If you like your music with a touch of warmth, the tubes handle that work gracefully.
LED-lit mechanical VU meters
The dual VU meters add a subtle sense of motion to your desk. They’re true mechanical meters powered by a dedicated IC, not a digital animation, so they move with a tactile kind of honesty. The warm backlight settles into the background and sets the tone for late evening listening.
Low-noise linear power supply
A 46W toroidal transformer provides clean, stable power with low ripple and low magnetic leakage. That means less noise, better channel separation, and more consistent performance from both the DAC and tube stages. The measured results back it up—≥114dB SNR and a ≤7uV noise floor.
Vintage-leaning design with solid thermals
The chassis follows FIIO’s squared, minimal desktop aesthetic, paired with a grille-pattern top plate that vents heat efficiently. The tubes stay comfortable, the internals stay stable, and you can settle into long listening without worrying about thermals.
NOS and OS modes
Two decoding modes let you shape the character of the sound. NOS mode keeps the original sample rate intact for a relaxed, effortless presentation. OS mode upsamples to 384kHz for a slightly more defined edge. It’s an easy way to fine-tune the feel of the music.
UAC1.0 and UAC2.0 compatibility
A simple lever switches between UAC1.0 and UAC2.0, which keeps the WARMER R2R friendly with consoles, computers, and mobile devices. No drivers needed. Just plug in the source you want and start playing.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series.
Favorite quotes:
"The truth may be twisted but never false."
"Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?"
"In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character.
*****SPOILERS*****
Pros:
The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits.
Cons:
Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks.
The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back.
*****
As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short.
Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.
