Jadis JA 80 or DA88S -'to be or not to be'

I am planning to buy Jadis JA 80 or DA88S in one or two weeks. Can You help me which one to choose. I have newest dCS Puccini which has preamplifier built-in. I have listened to JA80 (controlled by dCS) and DA88 in dealer and I had an impression that JA-80 is more spacious, more natural but ad home I have only listened to DA88. Is it true that monoblock has 3D soundstage (it is very important for me) ? And what about cables ? I am thinking about higher level cables of Tara Labs (0,8 Onboard ?), Audioquest (Sky ?). Stereovox (SEI600?), Siltech or Fadel Art (Coherence ?). Is this true that silver cables better sound with tubes than copper.

Thanks for good people help

The Jadis JA80 are excellent amplifiers, IMHO better (and 50% more expensive) than the DA88s.
Although choice of cable depends on taste and system, during my Jadis days I asked Jean-Paul Caffi advice about cables and he suggested the XLO signature, that I tried and bought. I have seen the signature 1.1 and 5.1 being sold at very nice prices in Europe.

Milimetr,
The ground loop hum is caused by the loop closing between power ground wires and the mass wires as you state. Lifting the ground wires can be unsafe - if you disconnect the signal cables the chassis is no more grounded. Some manufacturers ground the chassis to the power ground using 47 ohm 5 watt power resistors - low enough to be safe and high enough to "break" the low resistance ground loop.
