Loewe was once a great brand. It produced the highest quality equipment. But times change. From your proposals, depending on the model and money - he would, however, reach for Bose ,Sonos or Harman Citation.
Well today, in Romania the prices are:
Sonos Arc+Sub Mini+2 One SL : 1530 euro
Sonos Arc+Gen 3+2 One SL : 1700 euro
Loewe Klang Bar5+Sub5+ Speakers Klang Mr 1 : 1751 euro
Bose 900+Sub 700+Speakers : 1959 euro
Well i give back the sonos and purchase Loewe +sub + 2 mr1 speakers. Next week will be delivery to me. Total price 1620 euros
I hope will be better than sonos arc + sub + ls.
