I currently have a Marantz SR6004 that I will use as a processor. I also have 4 Marantz MA500 monoblocks that could be used to bi-amp each speaker.
Would any inexpensive amps perform better than my current set up? I have a limited budget (up to $1,000).
Some thoughts are below
1. Emotiva XPA-2
2. Used Parasound 5250
3. Other used amps?
Again, looking to mate the amp with the speakers based upon the criteria above. Emotiva has a good return policy, so I was thinking about a comparison to my current set up.
Suggestions are appreciated. Thanks.
What does "grip, dynamics and speed as well as resolving power" mean? Are these common or uncommon properties? What physical properties can they be equated to? I say that statements like this are poetry, and not even the person who wrote it can tell you how to reliably tes
t or otherwise rationally sift the market for.
The better question is whether or not any amplifier in existence would actually improve the sound quality of your system.
There is an extant technical test:
That technical test, while far from complete (the corresponding Stereophile magazine test report would be far more complete), would point out many audible failings were they to exist.
Let's look at your speakers:
"The Opus 2-3 is a full range, floorstanding speaker with a quoted frequency response of 33Hz to 43kHz. They carry a 91dB efficiency from a relatively easy to drive six Ohm load. The drivers consist of a one-inch Textile dome tweeter that sits at the very top of the front face, with a three-inch soft dome Textile midrange below and a pair of 10-inchTri-lam woven carbon fiber composite woofers for the bass. The speakers themselves are 48 inches tall, 12 and a half inches at their widest point and just over 17 inches deep and weigh 88 pounds each."
These appear to be well-designed speakers that will do a good job of exploiting the amplifiers in your receiver, and vice-versa.
If you are looking for improved sound quality your two apparently as yet totally unexploited avenues are adding a subwoofer and investigating room treatments. Your receiver also has Audessey, which may also provide some benefits, although it will provide more benefits the better the acoustics of your listening room become.
