Reviews

“Richness of sound, flawless performance and dynamics are also included – together with a features set that should leave hardly any wishes unfulfilled: an almost irresistible offer.”

Hifistatement
Klaus Schrätz

“Diamond scores with HiRes capability up to PCM 768 and DSD256. Thanks to its VOLTAiR technology, it operates with extremely low noise and distortion as well as rich in dynamics and with high resolution.”

lite-Magazin
Volker Frech

“Music lovers who exclusively use digital sources and are looking for a DAC/preamplifier that is as easy-to-use as it is versatile and, above all, has a powerful sound, have come to exactly the right place with the new SPL Diamond.”

Everything under control

The volume is adjusted with a solid, milled aluminum, rotary knob. The Alps RK27 “Big Blue” potentiometer gives a pleasant “spoon in the honey” rotary feel.

Source of joy

Up to 6 digital stereo sources can be connected to Diamond.

Diamond offers each a stereo USB and AES input as well as each two optical and coaxial stereo inputs. Via USB, both PCM audio and DSD audio can be converted. PCM audio is received in S/PDIF format, both coaxial (RCA), optical (Toslink F06) and balanced (AES/EBU).

The source selection is done via the selection control on the front. The selected input is also shown in the dot matrix LED display: USB, COA1, COA2, OPT1, OPT2 or AES.

After approximately two seconds, the display shows the type of clock source and the detected sampling rate.

Always in time

Diamond can not only synchronize to the clock integrated in the digitally fed source signal. As a specialist for digital players Diamond offers a word clock input. The source of the clock signal can be selected via the CLOCK switch.

Source = Diamond synchronizes to the digital clock in the source signal.
Word = Diamond synchronizes to the digital clock present at WORD IN.

Well informed

The DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if a streamer, computer, CD player or an external word clock is connected.

The detected sampling rate and the selected clock source are shown in the dot matrix LED display. For example, U768 is an acronym for a clock signal in the USB stream with asampling rate of 768 kHz.

SPL Diamond – Premium DAC with VOLTAiR technology

 

 

All variable – or Slave Thru

Diamond provides two stereo output pairs for connecting power amplifiers or active loudspeakers. One pair of outputs with XLR, the other with RCA outputs. Both have the same output signal, which is controlled by the volume control on the front panel.

The volume control for both outputs can be individually switched out of the signal path via DIP switch on the back of the device. For example, a headphone amplifier with its own volume control can be connected to one of the outputs.

The DAC768

The highly acclaimed AKM AK4490 Velvet Sound™ premium DAC chip is used as the converter chip in the digital-to-analogue converter, which thanks to its architecture reproduces the finest sound details.

It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256. In contrast to the DAC 768xs, the DAC768 not only offers an AES/EBU digital input, but also the SPL DLP120 with VOLTAiR technology.

The DLP120 (Dual Low-Pass)

The analog output of the DAC chip must be filtered by a low pass filter. Phonitor xe has two of them: One for PCM audio and one for DSD audio, since different roll-off frequencies are required.

In contrast to all other DACs in the world, the low pass filters here are built using VOLTAiR technology, which provides a plus in dynamics and headroom and sound.

Sounds good

With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.

The VOLTAiR Technology

The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.


The highest possible audio quality requires the highest possible audio operating voltage.

The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.

The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.

By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.

The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.

    Dog is in love with this Toy!
    Color: Assorted, Size: Medium
    This is a super great dog toy & one of the best we have purchased for miss "destroy the toy" dog! I have an Australian Cattle Dog who has a pretty big chomp reflex. She destroys most all of her ball toys in just a few minutes because she chomps so hard. So far, this is the only "open type" of dog ball toy she has not ruined quickly. It's actually lasted over a year so far! It is showing some wear & tear & a couple ares have almost been chomped through, but that would be expected with the way she chomps on it. She absolutely adores this toy & it is her total favorite! It has been well worth the money & then some for her. I've already bought a couple of "spares" but she is still playing with the original one I bought. Please note: I never, ever leave it alone with her! I use it only to throw or kick & for her to chase & retrieve. I try not to let her just chew & chomp on it, but that is what she'd really like to do. We play with it all year long, even in the snow. It's fun in winter because it does not sink & get lost in deep snow as quickly as a tennis ball sized toy would. It fills up a bit with snow, but that seems to make it even more fun for my dog. I highly recommend this toy. I just wish JW would offer it in some other brighter colors besides the blue. 01/06/2016 Update: My dog still is playing with this very same Hol-ee Roller X Extreme! I'd bought her a couple of spares but this 1st one is still holding up under her chompers! It's worn looking but has not torn or broke yet. I do not let her just sit and chomp on it though. It used as a retrieving and chasing toy, but she does get a few goods chomps in each time she gets it. We play with this toy basically every single day, so I'd say this is a very durable dog toy and the best one I have bought ! I highly recommend it.

    A Giggling Good Time for My Furry Friend!
    Color: Red, Size: Medium
    My dog absolutely loves the JW Pet Hol-ee Giggler Dog Toy Puzzle Ball! Here's why I think it's a great choice: Pros: Engaging Giggle: The giggle sound is so unpredictable and fun that it truly keeps my dog entertained. He goes nuts chasing it around and trying to figure out how to make it giggle more. Durable Rubber: This toy has held up surprisingly well to some intense chewing and playing. The natural rubber is tough but still gentle on his teeth. Versatile: It's more than just a noisemaker! It's great for fetch, and I can even stuff it with treats to turn it into a puzzle toy. Cons: Giggle Mechanism: The giggle tube inside can be a little delicate. If your dog is a super aggressive chewer, they might be able to dismantle it. Not for Quiet Time: If you want a silent toy, this isn't it! The giggle can be quite loud when your dog is really going at it. Overall: I would definitely recommend the JW Pet Hol-ee Giggler to other dog owners. It's a fun, durable, and unique toy that provides a lot of stimulation for pups. Just be aware of the potential for the giggling mechanism to break under heavy chewing, and be prepared for some added noise!

    DIEGO'S FAVORITE OUTSIDE BALL!
    Color: Assorted, Size: Medium
    JW PET COMPANY HOL-EE ROLLER EXTREME This is the second HOL-EE ROLLER ball we have purchased for our Diego. He LOVES these! He now owns a black one and a blue one. He loves to toss these around the yard all by himself or have us throw them to him. He looks so adorable when he comes running back to us, with the HOL-EE ROLLER in his mouth and he has the sweetest expression on his face and is so happy he is prancing! He is a rescue Pit mix from PR. He survived Hurricane Maria and was there before, during, and after. If he could only tell us his tale. The ball is sturdy. The honey comb design gives your baby the ability to grasp and hold the ball. Diego also likes to hold the ball down and gnaw on it. The ball has proven to be safe against his little vampire teeth. The blue ball was in our yard the entire winter during every type of element you can think of. It is is great shape. Diego plays with these balls constantly while outside. They are sturdy and he is able to get a nice grip on them. These balls are tested by the company to make certain they do not contain any harmful chemicals. The ball has plenty of bounce to it too! The balls come in different colors but which color you receive will be a surprise. JW products are AWESOME. Diego also has a trio of smaller indoor balls that he has had for three years now. They are still like brand new. He loves to play with these. They have grips on the outside for him to try to chew on, but he can't destroy them. JW has other types of pet toys and products available for you. Check them out. Your dog will thank you.

    Most favorite
    Color: Red, Size: Medium
    My fur babies love these balls they are their favorite. Any size dog can play with it because of how it's made. it easy to play with. It's made with a lot of opening and is made of a soft rubber. My Shepherd pup and Boston's love to play with it, and I had to buy 3 so they don't fight over it. The giggler will break easy and even the first day on rough riders, but they can still enjoy the ball itself even without the giggler. It size is about 4in. If Amazon gave halves Id give it a 3.5 because of the giggler breaking so easily but otherwise my girls still love this ball.
