What's NEW ??
We OEM designed and manufactured a low cost series of products with brand name "AUDIO SURTA" , by building with larger quantity with fixed design and chassis , the selling cost can lowered to just $999 (pre-amp) and $1,199 (power amp) without sacrify the sound quality. Detail product information please check www.AudioSutra.com
For all vinyl lovers, we have designed a universal AC power generator named " Perfect Power 1.0" , this is an AC power supply which can let you set to either locked 50Hz or 60Hz or vary from 38Hz - 168Hz range, so that you can use turntable from any part of the world, output voltage can vary from 0 - 120VAC. The speciality of this power generator is its "Perfect" sinewave, if you ever test your AC outlet waveform, you will know it is not a very good looking sinewave but some distorted sinewave with lots of noise . Just Imagine your valuable turnable system feed with such poorly constructed waveform, what level of degrade will you get in return ? This power generator use 64x over-sampling PCM digital-to-analog technique instead of switching power supply , in order to generate a Perfect sinewave to power up your turnable (max. output power 30W), so the most smooth tonal effect can be achieved, and due to the variable freq design, you can use 50Hz turntable in Canada/ USA without problems. By adding a 120/230V transformer, you can also power up a 50Hz 230V turnable shipped from England. The price tag of this generator is only a fraction of those big names which even don't have such flexibilities and analog purity.

We have newly designed a very interesting hi-tech multifunction display , it is named "SMART Monitor 1.0", a display which can let you set it to be a VU meter , or CRO (scope with Vrms readout ) , MON (like a heart beat monitor), HYPNO (circular pattern which can hypnotize you) , FFT (spectrum analyser) or a name plate (such as display your name, pet's name...etc), this monitor device have a very sensitive DC offset detection circuit, whenever the input signal has harmful DC components, it will trigger the protection and disable the output to safe your expensive speaker, with this SMART monitor, you can use any gear equipped with this meter as a measuring equipment , and to test out any part of your system, such as check out the L/R channel balance, waveform distortion...etc. Come with a test CD with frequency tone from 25Hz to 20Khz. (We can program the name plate to your choice of display when order being placed, 100% custom made to reflect your person taste ). This meter can work indenpently or can install into any of our pre-amp , power amp, integrated amp, buffer ...etc, just to make music enjoyment become more fun and unique. We also sell this meter in module form to let you use in your own projects or gears. We also make a small gadget with this monitor name "EASY SCOPE 1.0 / 1.1 " , which is a self-contained test equipment for audio system, with even more features integrated into a small box for your testing needs.

Our new USB-DAC series with 1x sampling rate introduced on Mar 2010, 3 different models combine with 3 different tube upgrade option, which adds a total of 9 different models to our DAC family, incredible bang-for-buck price tag, check out our DAC section for more details. DAC page
We have new design and manufacturing break though since the year end of 2008, all our new products has further enhanced and improved design on the sonic performances, further lowering of the noise floor, enhanced musicality as well as strengthened internal architectures. We call this "Mark II" design which distinct from our previous produced products. Any previous products before 2009 can bring in for new "Mark II" upgrade, cost vary with different level of upgrades..
For phono pre-amp ,our new design have 5 different MC gain settings instead of 2, and further lower in noise level for both MC and MM due to new circuit design and constructions . Which can easily surpass any other manufacturer's high-end tube phono pre-amp with just a fraction of their price. For P-105, the RCA and XLR output impedance can even lowered to 200ohm , so driving any 600ohm XLR input is surely no problem at all. We also offer a NEW designed MC/MM phono P-001 with unbelievalbe bang-for-buck promotional price. Phono page
In the year start of 2010 , we offer a totally new phono circuit which have superb MC and MM quality but with lower manufacturing cost , so we can integrate this new phono stage into whatever model of products to make it LP compatible in order to adapte the growing community. An MC+MM embedded phono stage start from only C$480 !! The sonic performance can easily outperformce those commercial available models selling around $2-4K. In home auditon is now possible with our outboard version.
We have designed several "Budget" version of Hybrid amplifier to serve even wider group of audiophiles, which is semi PCB and semi handwired just to cut the manufacturing cost but retain the best possible tonal quality, they are 25W and 70W per channel respectively, check out the Hybrid amp section for more details. Hybrid Amp page
For pre-amplifier, we have a new break through in our singled-end and balanced amplification circuit, which have much higher dynamics and super high density sound but still maintain a very sweet and smooth charactieristics of our original tube designs, much lowered output impedance with better bass control and punch , at the same time with ultra transparent and smooth sounding as well as sweet and tender tonal quality. Those new designs are all implimented in our new QA-8001 model. Check it out in our pre-amplifier section. Pre-Amp Page . This new technology can even transplant into whatever model of our pre-amplifiers with a very reasonable cost. We also introduce different levels of upgrades for different models. Each level of upgrade can futher boost the performance of the unit which you will definitely need to spend thousands to get from other manufacturers. Some of the higher models can even have FREE level 1 upgrade when new order placed.
All new Mk2 design pre-amp come with our newly design water proof volume control pot, which eliminate any oxidation contact problem of the viper and carbon film inside the pot.
We also developed a totally new state-of-the-art microprocessor controlled high tech volume pot, which comes with digital display for volume level with 100 micro step resolution, you can also select between " Dual Volume "; or " Volume + Balance " mode. This ultra new design make the music signal pass thru the minimal components, and no need to pass any solid-state device or contact points (those so called hi-end step volume control need to pass at least two contact points), and the sound quality is so pure , natural and open like no volume pot at all . Any model of our gear can install this optional ultra-hi-end volume control for a cost of even lower than some hi-end step volume controls. DIY customer can order this volume pot as modules to put into their own gears for performance upgrade. Our new 10000 series of pre-amplifier already include this super volume pot in the design.
