Which one to buy: UpTone USB REGEN or Intona USB Isolator?

[deliad]

hi,

 

i need the usb isolator to solve me problems of pops and clicks that happens sometimes (when they happen - its terrible).

 

i'm using MOTU Ultralite AVB Sound card which has his own power supply - this sound card is a USB 2 HIGH SPEED Device and a DELL M4800 Laptop.

 

Questions:

 

1. Your USB Isolator will fit to my Soundcard?

 

2. Do you really think it will eliminate the clicks and pops and the data fails?

 

3.Do you think AC Power Coordinator like Furman or Samson will help?

 

4.I may change my Sound Card 12VDC PSU to linear Power Supply,Do you think its needed if i buy the AC Power Coordinator?

 

Please answer me in detail as more as you can,tell me your professional advise, it is really important to me
