  • QAV Volumio I²S High Res Bit-perfect Music Streamer and Player with DAC Out

    • Now a complete solution of Volumio streaming and DAC with power supply within a chassis of fully decked-out connectors and colour display screen
    • Power filter hat has a higher capacitance value than the standalone one in total to give the best possible power source
    • DAC hat is a major improvement using Sabre ESS 9038Q2M chip with full RCA, 3.5mm, S/PDIF Coaxial and Toslink and I²S HDMI output
    • Clean digital outputs from S/PDIF and I²S to external DACs give high quality and pristine signals that can sound better than using USB
    • I²S out allows higher sampling rates up to PCM384 and DoP256 while S/PDIF is capped to PCM192 and DoP64 – generally suffice for most
    • Including the power filter hat, there are a total 3 stages of power filtering for RPI to sound great
    • Having excellent components of power source built inside QAV ensures the RPI and DAC are performing optimally
    • Even better fuses made for hifi from Rod Rain Audio are used at the power IEC inlet
    • 3.5 inch colourful and sharp screen in front provides useful information in date, time and details of the music being played with any accompanying album art stored

  • QA Triple Aces Supreme Audio Ground Box with 4N Purity Triple Metal Solid Core Grounding Cable

    • Read more here for the detail run down of the process to the beginning and production of the QA Triple Aces
    • Made with significant step ups in all areas from our best selller original ground box
    • More than a dozen of ingredients, over a third more than original QA Premium Ground Box
    • The addition of 3 types of fine metal powder in 4N purity give rise to the name of this box
    • Pure silver powder is one crucial component of the three, with pure copper being the other
    • Thick walls of black walnut box houses the 6kg worth of content with super strength while the smooth finish and beautiful grain oozes class
    • Authentic CMC binding post with high-quality gold plating provides great conductivity from the grounding cable to the interior mix
    • Includes 1x 50cm grounding cable constructed from scratch, fully hand-made by QA as well, with pure 4N silver and copper single core twisted with a 3rd metal core, as per the internal mix, QA could not disclose
    • Sheathed with cotton, wrapped with heat shrink before being sleeved with cotton-PET sleeve, the grounding cable is terminated on the ends from Puresonic
    • Excellent tech and make of Puresonic connectors resulted in a high-end and proprietary-designed grounding cable that is a perfect match to the Triple Aces as far as the three metals are consistently present
    • Default configuration of the grounding cable is spade to banana. Available to choose among banana, spades or RCA
    • Inclusion of 4x precisely-machined spikes tipped with copper provides sturdy stabilisation and isolation free from unwanted vibration on surface Triple Aces is seated on

  • Upgraded and Modified BG7TBL Higher Quality 10MHz OCXO Master Clock with Counter Display

    Only limited sets available!

    • Recently more higher grade of consumer audio equipment comes built-in with Clock inputs
    • Input of an external Clock provides a more stable and consistent frequency timing, overwriting the often less precise on-board ones
    • Very noticeably, you can immediately feel the improved clarity and ‘timing’ in the music. The notes are seemingly much more aligned, producing a very clear imaging of sound with the background turning instantly transparent and noise-free
    • The fact the music just sounds right is a huge step up and is a thoroughly enjoyable improvement
    • BG7TBL has been a very popular Clock generator producer in China which has gathered massive praise and compliments over the years
    • To better improve the product, QA upgraded from the stock basic caps to Vishay BC caps
    • At the core of the Master Clock, QA chose and upgraded to using Oscilloquartz (datasheet) and Toyocom OCXOs, made in Switzerland and Japan respectively, the higher quality and precision of the OCXO is a huge upgrade over the stock one which is more commonly made in China
    • Only the finest few of the OCXOs QA has sourced from makes the final selection to be used in the upgrade
    • We have calibrated the output to be within ± 3 Hz of the reference 10MHz, an accuracy deemed respectable and within expectation for the price
    • The addition of a frequency counter onto the chassis as a touch of an aesthetical industrial approach, displaying the real-time output frequency of the Master Clock
    • With its own components and oscillators at circuit level, it is important to understand the perfectly-normal drifting of timing in the counter itself can affect another ± 5 Hz of output deviation
    • 2 toggle switches control the frequency counter, while the ground post allows ground box to be connected easily which further improves the sound in transparency and details
    • 2 ways of placement – either on the back or on its side
    • A warm up time of at least 5-7 minute is needed for the frequency to stabilise. 15 minutes onwards will be primed for use
    • Comes with a SG/UK-plug type 12V power adapter and a 50cm 50-ohm BNC cable
    • 1.47Vrms, 4.41Vpp, 16.24 dBm
    • Can get together with our 6dB RF Attenuator as a package price to pad the output level down if required
    • 1-year warranty from QA

  • Raspberry Pi Power Conditioning Filter Add-on Hat for Outstanding Clean Power Supply Improving Dynamics and Transparency

    • Highly recommended for use with RPI 4 model B
    • Powered by DC input, the power goes through a series of capacitors arrays filtering and stabilising the current before powering the RPI through the GPIO pins
    • Powering of Pi through the GPIO pins is a little bit more direct than the Type C path,
    • Can similarly provide a cleaner source of power directly to any additional hats on top of it through the GPIO pins for them to run on
    • Improved transparency, darker background and better dynamics can be expected with this hat
    • A UK/SG type 5V 3A DC power adapter is included
    • Does not come with acrylic covers

  • 50-ohm 3W Gold-plated Centre Pin BNC 6dB RF Attenuator

    FREE Singapore Shipping (non-trackable)! Top up $4 for Qxpress delivery.

    • Audiophile-grade RF attenuator for use when Clock-input devices have a required input level lower than that of the Master Clock and Clock generators
    • Although there is no apparent issue with connecting a Sine Wave output higher that of the required level, padding the RF level down is a safe and assured way of syncing the Clocks correctly
    • 6dB attenuators is padding the level by 50%
    • Audiophile-grade construction with gold-plated centre pin and strong connection ensure there is practically no loss or degradation in RF signal transmission
