As a consumer there’s a lot out there for you to choose when it comes to home theater electronics.

Starting with source components do you buy a CD player, a Blu-ray player, a media server or all of the above?

When it comes to managing these sources and powering your speakers do you buy a single-box A/V receiver that incorporates everything anyone could possibly ever need or do you buy “separates,” which in audiophile speak means an amplifier and preamplifier/processor.

A good case can be made for either category. Receivers offer convenience and cost effectiveness, while separates provide higher levels of performance and an easier upgrade path for hardware and even firmware updates.

In terms of pure costs A/V receivers run from about $300 to $8,000 and separate components can run from about $1,000 to $50,000, excluding esoteric two-channel audiophile gear. So you can power a range of speakers from the exotic to the more budget-friendly.

Focusing specifically on amplifiers and without diving too deep into the audiophile/Vulcan vocabulary, those wanting their systems to live free and prosper should consider essential specifications like power ratings and frequency response, as well as other things like warranties.

A good rule of thumb when looking at the power ratings of an amplifier is to see what it produces when driving a 4-ohm load and 8-ohm load. An amplifier should produce a noticeably higher rating at 4 ohms than 8 ohms. Also look at other ratings such as continuous output. Cheaper amplifiers will often be quoted with a “peak” number that indicates what it produces for a quick second. Robust amplifiers are usually rated for continuous power or RMS (root mean square) and these ratings are used to indicate how much power an amp produces over a long period of time.

Other ratings such as distortion can also be helpful, but consider that in many cases users are not going to hear the differences between a hundredth or a thousandth percent of distortion.

Quoting:  bob archer on 05/16 at 09:46 AM

I have been told the company’s products are good, but I don’t recall seeing them exhibit at a show like CES, CEDIA or EHX.

It may be for the same reason that I choose not to represent my company at trade shows:

They are expensive

You see 30 like vendors of sameness product all telling the same basic thing: We are the best

Emotiva/Outlaw have for better or worse staked their claim on the power of the internet and the communities it builds. If you as a consumer aren’t smart enough to get out there and research your options, you may need to buy from something you only knew about via a trade show.

Hi PMX13 like I said the products chosen in this were done so randomly.

I can appreciate the value of Emotiva and as a direct to consumer company it is essential for them to be responsive to consumer inquiries so that doesn’t surprise me.

I cannot say with any convection however that it stacks up to these companies that have years of experience in the design and engineering of a product.

I also would never discount the value of a dealer network. A good dealer can be overlooked with the ability to educate, demonstrate and service a client after the sale.

I have had an “entry level” Emotiva system for over two years.  For under $900, I replaced systems by Onkyo & Yamaha with an Emotiva 6x125 watts & a matching pre/pro that has been fantastic to hear.  While I appreciate the quality & reputation of the manufacturers on this list, to me, they are not esoteric so much as boutique (Where’s McKintosh???).  Emotiva & Outlaw are two up and coming companies that do not play the multi-tier distribution network mark-up game.  Both are prime players for enthusiasts looking for Mustang 5.0 or Camaro 6.0 performance without paying Mercedes AMG pricing.

For a DIY’er, Emotiva still focuses on customer service. If you send them an email, you will get a personal response from their customer service manager within 24 hours.  Their forum is also available to tap into their owner base.  (Sales questions are much faster.)  I didn’t want to ship my unit back for a (complementary) firmware upgrade, so they sent me the cable I needed and walked me through the process

Does anyone know how much it costs to participate at Cedia???

AT AUDIOHOLICS.COM:
“The [Emotiva] XPA-2 is not only the most powerful that has come across my test bench, but it represents the best value in consumer two-channel amplification that I’ve ever seen.”

Hi Psmo, I wouldn’t say there’s anything esoteric about the brands in this story.

All of these brands have long histories of producing quality products, they cover a range of price points and they are all widely distributed within the electronics market.

I would say that Emotiva needs to do more outreach to consumers and dealers.

I am very leery of buying anything whether it’s an amp, a guitar or anything else site unseen.

How did you compare your Emotiva amp to others?

A trip to a dealer allows you to compare NAD to Bryston, Rotel to Classe, etc.

I make the same comparisons at trade events or visiting dealers.

Like I said too I am aware of the brand and it does come recommended as a value proposition, but keep in mind that these brands are no more Esoteric than Emotiva.

Maybe you should stay away from the esoteric side of the events and branch out a little. http://emotiva.com/news.shtm
while at their web site maybe you could read some of the reviews, you know, to brush up. Just a thought.
