Fix Amp or Buy new?

Hi folks!

New forum poster here. I did not know where to turn.

I would like some advice on whether or not to fix my amp or buy a new one. Here is my setup:

Main power amp: Sony STRDA9000ES Channel Power Rating : 7.1 Channel Power Rating: 200W x 7 Amp Power (8 ohms, 20Hz-20kHz, THD 0.15%)

Processor: Marantz AV7005

Speakers: 7.2 system

Room: Dedicated (pics below)

 

Problem: My Sony Amp retailed for around 6k when I bought it. I was able to get a crazy deal on it and have been using it to power my system. I am very happy with how it sounds when matched with the Marantz. A few days ago I got a Protect 11 error on the amp and have been unable to fix the issue. Sony will fix this amp for $945 flat rate. This price includes shipping and tax. Flat rate no matter the issue.

Should I fix this amp or get replace it with the Marantz MM8077 ($2240 +gst) or the Integra DTA 70.1 ($1840 +gst) or something is that range? 

I realize that a good amp should last "a lifetime" and the processor is what is usually upgraded with new tech. I would very much appreciate the input.

First, I don't think that unit is a power amp, although you may

be using it as one. It is an AV Receiver and wouldn't need the Marantz AV7005 processor to work in your system. For almost $1,000 in repairs I'd be inclined to look into an Emotiva XPA-2 to drive your mains and an XPA-5 for the center and surrounds ($1,448 US delivered in the US). The Sony STR-DA9000ES does not output 200 watts per channel with all channels driven, it only reaches that specification with two channels driven. The Emotiva amps are rated with all channels driven, 300 wpc for the two channel XPA-2 and 200 wpc for the five channel XPA-5. What loudspeaker system do you have?

I think these amplifiers will make a significant improvement in your home theater system.

Hi Jackfish, I appreciate

Hi Jackfish,

I appreciate your response and input. You are correct in the assumption that I am using the receiver as a power block. I have it connected using RCA interconnects to my processor. 

My speakers, which I will be updating in the future, are:

NHT ST4 : http://www.nhthifi.com/ST4

NHT SC2: http://www.nhthifi.com/ServiceCenter/SC

NHT SB3 for rears: http://www.nhthifi.com/ServiceCenter/SB3

Mirage OMR2 for side: http://www.audioreview.com/cat/speakers/floorstanding-speakers/mirage-lo...

Velodyne Optimum 10's x2: http://velodyne.com/subwoofers/optimum-series/optimum-10-black.html

 

Comparing these Emotiva amplifiers to the two amp's I asked about in the OP, what would you recommend? Value is important.

I've done my research and you

I've done my research and you seem to have nailed my needs. Im sad about not giving my business to the locals guys, but in the end they seem to be great value.
