It is however a beast of an amplifier. First 5 watts in Class A so down at moderate volumes it absolutely purrs. We connected it to a Modulus 3A line stage and streamed to a newly brought in Linn Keilidh speaker system and it was just a spectacular combination. So satisfying and full bodied. It's a can't miss power amplifier fully serviced by our expert tech staff and ready to play beautifully in its next owners setup. \u003c\/p\u003e\n\u003cp\u003eCome demo this fine Onkyo \"Hulk\" here in Andover or hit the buy now button and we'll get it off to you straight away.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOnkyo Integra M-504 \"Hulk\" Power Amp: $1299.00 plus sales tax and shipping when applicable\u003c\/strong\u003e\u003c\/p\u003e","brand":"Holt Hill Audio","offers":[{"title":"Default Title","offer_id":43054083047491,"sku":null,"price":1299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2197\/6387\/files\/PhotoMar202026_35007PM.jpg?v=1774047921","url":"https:\/\/holthill.com\/products\/onkyo-integra-m504","provider":"Holt Hill Audio","version":"1.0","type":"link"}
