Receiver: Onkyo TX-8222 (http://www.eu.onkyo.com/products/pro...n_4372499.html)

Speakers: Heco Victa 200 (http://www.heco.ch/EN/produkte/produ...odukte&sid=161)

Jack to RCA cable: HiDiamond HID (http://www.hidiamond.it/prodottie.php?id_scheda=31)

Power cables: Monster XP-HP Monster Cable (http://www.videosell.it/scheda_prodo...D_articolo=278)

Do you think it would be better to change the receiver with an Onkyo Class D integrated amplier like the A-9355? (http://www.eu.onkyo.com/products/pro...n_5368139.html)

What about that Jack to RCA cable? It is really needed or I could use something for less than those 39 euros?

Any opinions will be greatly appreciated.
