I have reduced my hi-fi system from several separates down to one streaming preamp with active speakers so don't need this Audiolab DC Block any more (along with five others which I am listing separately).
It is quite a noticeable improvement putting one of these in to a system, in particular reduced transformer noise and less background noise at high volumes caused by saturation and RF interference.
It is in excellent condition and perfect working order and in its original packaging with UK mains cables and user guide.
Shipping is to UK addresses only, tracked and insured.
Please note that I will only ship to an overseas buyer who uses the ebay global shipping programme.
