Introducing the new Formula xHD


The Optologic R2R conversion system


Aqua believes that the more musical D/A conversion system is based on the circuit usually identified as "resistor ladder".

This technology has been substituted in the mass-market by the so-called sigma-delta converters.

The sigma-delta converter is a near-completely digital circuit and for this reason it can be can be integrated on silicon and produced at low-cost.

A quality resistor ladder DAC instead uses a circuit based on a set of high precision discrete resistors: at least 2 resistor banks, one for each stereo channel.

The Formula DAC is the first in the aqua’s production to show a proprietary D/A conversion system, that we name Optologic.

The signals sent to the resistor ladders are generated by a proprietary digital circuit, implemented inside an FPGA (Field Programmable Gate Array).

Formula has a sign-magnitude converter structure, and this requires not two but four 24 bit resistors banks, each one made of very low tolerance discrete resistors.

In order to separate the digital section from the sensitive analog circuits,  galvanic and magnetic isolations are implemented between the FPGA and the four branches of the R2R ladder converter.

This creates complete isolation of all digital circuitry - including the clock - from the analogue section, for a clean, noiseless ground plane. It also plays the main role in the differential management of the R2R ladders, achieving perfect symmetry between the counter-phase halves. The result is the highest tonal contrast and naturalness.



Pure 1x native sample rate DAC


The Formula, like the other aqua models, is a digital filter-less DAC.

Our conviction is that in spite of the instrumental measurements showed by upsampling / oversampling DACs, they rarely are able to produce the same emotional and realistic results.





A third important aspect in the aqua production is the modularity of the various electronic circuits.

aqua equipment are not short life products: as modular, they are open to future improvements and to follow the evolution of the technology.

Formula is made of a set of circuits every one developed on a separate printed circuit board easily interchangeable.

As an example, each of the four resistors banks of the converter is separate and mounted on connectors.



State of the art digital and analog electronics


As explained before, the Formula DAC uses no digital filter or any other compensation, relying instead on maniacal attention to each sub-circuit.

The separate analog and digital power supplies are executed purely by extensive use of discrete BJT, Mosfet, J-Fet and ultra-fast diodes.

Passive parts were selected not just for the best sonic result but also for their top quality, longevity and reliability. With the exception of six superior electrolytic capacitors, all other caps are Tantalum, solid-polymer OS-CON and double-metalized MKP.

The signal path itself is direct-coupled and completely capacitor-free.

The two output stages (one single-ended, one transformer-coupled balanced) use discrete BJT and J-Fet with metal-film resistors. All the electronics parts show an ultra-low RF noise.

An advanced ARM microcontroller manages the user interface on the front panel, the IR remote command and the communication port (serial, RS232 standard).


The xHD update


This update has required significant optimization of code for the main FPGA of R2R ladder DAC which has improved sound quality.


The new hybrid USB XMOS xCore 200 (dual core) + FPGA circuitry enables the high-resolution file playback up to 768kHz PCM and native DSD512

In The Groove KA-RC-1 Ultrasonic Record Cleaning System




No matter how you store and use your records they inevitably will require maintenance. When playing records, dust particles and contaminants always build up on the stylus as the tone arm moves across the record. This accumulation on the needle also "dulls" the sound.


The emergence of the dreaded "audible pops" and "crackle sounds" heard are caused by dirt, grime and particles lodged in the record grooves themselves being hit by the needle, as well as static discharges, all amplified by the cartridge. All are annoying.


Even new and latest pressings are subject to the same conditions as your old collection. Their release agents are found on the record from the pressing process and must be removed prior to use, otherwise they attract at an alarming rate dust and other airborne contaminants.


Therefore, recommended is the continual maintenance and care of your records by way of regular cleanings which in turn reduces these unwanted pops and augments therefore one's listening pleasure and audition. Cleaning WILL NOT remove unwanted sounds caused by scratches on the record surface and depending on the age and condition of the record, even repeated cleanings may or may not restore the record to like new condition, but reduces the overall undesirable effect previously described.



EVERY ONE'S AN EXPERT! There is much nonsense published regarding the cleaning of records. Soaps, chemical mixes and brews, and especially the use of large portions of alcohol etc., these all affect the record negatively either during or after cleaning. Air drying of chemicals that are not physically removed further creates issues that are cumulative over time. Indeed, to the rescue, ultrasonic cleaners have been around for decades and its use and attributes are well known and while care must also be taken as to the introduction of chemicals in the ultrasonic bath, this cleaning technology is a very valuable tool to use. We differ in how we handle the record itself. Nonsense though, are some of the extravagant prices on cleaning machines available as all ultrasonics operate the same way. >>Many add 2.5 L of alcohol to 6 L of water, dangerous!<<<


The KirmussAudio Model KA-RC-1 revolutionizes the way we clean records. First and foremost: a Patented record suspension system assures where records of any speed and size see their grooves cleaned safely. No damage to the record by mechanical intrusion of skewers and the like.


Secondly, only distiulled water with a maximum of 45 mL ( 1.5 oz) of ISA 71% solution constitutes the bath and where applied to the record in its second cycle is an anti-bacterial surfactant, pre and post wash neutral liquid agent is used. Ultrasonics need a surfactant to aid in the cavitation of the water solution to better clean and remove contaminants.


Third: affordability. For the price of $795.00, everyone can enjoy their collection, restore and maintain it.





Warranty: 2 years parts and labor. Please fill out and mail in the warranty card that comes with your product.


There is no filter in the bath or water exchange. When the water becomes dirty, simply drain it and replace it with fresh distilled water. Drainage valve and hose included.


Timer range: 1 min to 15 min +-


Both sides of the record are cleaned at the same time.


Cleaning time takes 5 min.


Tank material: Stainless steel SUS304


Tank Capacity: 2.0 US Gallons


You can clean at one time: 2 LP's, one 78 and one 45.


20 to 25 Records can be cleaned with one tank of water. Drainage hose is provided for fast and easy drainage.


There is no dryer, you hand dry. Lint free blotting towels are included! IDEA: Get a dish drying rack or something similar to put your cleaned records in. You can let them dry naturally or blow a fan across them while they are in the rack.


The Ultrasonic frequency is 35 khz


Outside size (without records inserted): Width 21.5" by High 10.75" by Deep 11.5"



Everything you need comes with the cleaning machine, nothing else to buy; drainage hose, cleaning brushes, blotting towels, all chemicals, etc. The first photo shows some of these accessories. It is plug and play ready!


THE TEAM: After 3 years of extensive research and trials audiophile and business owner Charles Kirmuss and recognized turntable restoration expert Dr. Eric Watson developed an affordable, simple to use system. With cUl and UL/CE Electrical and Safety Approvals our affordable system will increase your listening pleasure by removing most of those annoying unwanted pops and crackling sounds from both new and old records. This is not some home-made product. With Patents both issued and pending, ware also sure that You will be very pleased with the results and benefit from many years of satisfaction with our revolutionary ultrasonic based cleaner.

Bryston proudly introduces the new BDP-3!

A New Reference in High Performance


Bryston's new BDP-3 replaces the BDP-2 as our flagship high resolution digital player. Lets see what's changed:


What's new:

  • Brand new main board with extremely fast Intel processor and 8 gigabytes of internal memory means way faster startup times, much quicker library updates, improved user interface responsiveness, and plenty of horsepower to spare for additional features to come.
  • USB 3.0 ports have been added to further improve the speed at which the BDP updates music libraries stored on USB 3.0 attached hard drives and SSDs. A total of 3 USB 3.0 ports and 5 USB 2.0 ports are available to maximize connection possibilities.
  • An all new totally separate USB bus is included to enable even greater compatibility with USB DACs. Specifically, those that utilize Streamlength protocol such as Ayre, Wavelength, Audioquest, Berkeley, and more can now have USB storage and the DAC connected on entirely separate controllers.

What's familiar:

  • The precisely machined aluminum dress panel and high quality steel case look similar to our BDP-2 and BDP-1.
  • Sound quality remains world class. The audio output remains based around the IAD (Integrated Audio Device) we introduced in the later runs of our BDP-2.
  • As with all full size BDPs, the BDP-3 is powered from a high current low noise linear power supply which protects the integrity of the high frequency digital audio signal path by not exposing it to an on-board switch mode power supply.
  • The price is USD$3495 - a mere $200 increase over the BDP-2 means the new model will continue to be the standard bearer in digital audio playback without breaking the bank.
