 Why it built in ES9028 
			pro ?
 We applied 
			ESS9028Pro but not ESS9038Pro because the ESS9028Pro much cheaper 
			and already can offer the very low distortion.
 We accept custom order ESS9038 Pro 
			version, leadtime is 15 days, price USD963 with 3 pc TCXOs build in.
 
 ESS9028 Pro specs:
 
  
 Who need the AS-1:
 AS-1 is not the lowest 
			distortion DAC in world, but it had the ultra low distortion and 
			price is not expensive.
 AS-1 is not only declare 
			with the words has low 
			distortion,  we offer the measure diagram for every single unit (It 
			is normal that the THD has few DB different, the first 20 units 
			offer AP SYS-2722 measure diagram, after that will offer AP ATS-2 measure 
			diagram, ATS-2 measure diagram will has around 6DB worst than 
			SYS-2722¡A but it is not mean the unit performance worse),  verify by the professional 
			instruments is welcome.
 We known that the proper 
			2nd THD makes the sound become smooth and rich,  the proper 3rd THD 
			makes the sound become transparency and lively, how to adjust the level of 
			2nd and 3rd THD is the secret technology of the designers, that is why some audio 
			devices have the higher distortion like phono, and some few very 
			expensive European made audio devices  had better musical to most 
			people than some others low distortion devices .
 We had not applied 
			technology method to adjust the AS-1 THD effect the sound flavor, we just made it has the 
			very low distortion , and through selected the different parts apply 
			to keep the sound listening pleasant . It is not the audio-gd house sound 
			style.
 Who need the AS-1?
 I guess that is in 
			below:
 1, Who concern the 
			specs at first .
 2, Who want a 
			monitor sound to test the cable, room, speakers  or somethings 
			of audio.
 
 Some specs 
			of the AS-1 (Measured by AP SYS-2722,unit with 300 hrs burn in):
 THD . (the same unit measure in 
			same minute , the peak level result may has few DB different, so I test the 
			same unit in different time and post the result in below) :
 
  
 
  
 
  
 
   
 Distortion to Frequency 
			(This diagram effect has less effect by the different test time):
 
  
 Frequency band  (This diagram effect has less effect by the 
			different test time):
 
  
 Jitter test with 12KHz with the stock clocks. (The clock burn in 
			time and power supply clean can have few DB effect )
