HE-500, LCD2, D5000, DT770, SR80, on a speaker amp (Emotiva mini-X A-100) Project - Page 160

post #2386 of 3793

HE-500 and LCD-2 are all good sounding on Emotiva. I'll finally give my vote for the LCD-3 as well with Emotiva. HE-6 is the one that'd really benefit. I also think the Emotiva can vary in performance quite a bit depending on source.

Thinking about NFB-11.32, 15.32, 12, 10.32 etc.


 I compared the 11.32 amp out with the emotiva amp output on the he-500:

Just wondering if anyone can check my physics here. I'm trying to calculate the power I'm getting into my HE-400. 

Using the relationship P_2 = P_1 * (R_1 / R_2) (That's power and resistance), I have P_1 =  50 W and R_1 = 8 ohms for the Emotiva, and R_2 = 35 ohms for the HE-400, so P_2 = 50 * (8/35) = 11.4 W.

With 300 ohm serial resistors, I have R_2 = 300+35, so P_2 = 50 * (8 / 335) = 1.2 W. About the same as what a Magni would deliver with no resistors in the chain, yes? Interesting. I'm happy that I didn't get a Magni though. The Emotiva is way cooler. 

Does it actually work this way? The Emotiva doesn't have 100 W into 4 ohms, so it seems like this linear model isn't quite right?

IMO, For HE500 : Price, Performance, potential to drive speakers, IMO the Emotiva would come out ahead in most, if not all, categories when compared to even higher audio grade models that would cost you $$$ more.  To me, the tipping $ price point start around $800.  The only trouble is that you have to make an adapter to connect your headphones.  I liked the Emotiva so much I put a 1/4" TRS in the front panel permanently.  My opinion about the Emotiva has not changed one bit even after I purchased a Woo WA22.  Yes, I prefer my HE500 driven by the Emotiva over my WA22.

 

People's take and preferences might vary.

The only reason I don't have the Emotiva anymore is because of the size, otherwise it was my first choice to drive the HE-500 as well. My old NFB 11.32 could not reach the level of Emotiva's performance either. I settled with the Lepai for the size, price/performance, and tone control.

I'm thinking I might as get a cheap used Audio-gd dac/amp then, might be a better solution in my case
So Emotiva amp is probably more useful for the HE-6 I take it?

 

Compared an Audio-GD NFB-10SE to the Little Dot MKVI+ and Emotiva A100. The Audio-GD unit was below the performance of the latter two by quite a bit. The Emotiva edged the Little dot by a bit as well with orthos.

I agree with most of what you said. I owned several tube amps. The Emotiva does something unique with the treble. The Mini-x has many of the characteristics that I would associate with a tube amp more similar to the Woo WA5LE 300B based amp in my opinion.  The mini has somewhat like a type of  shimmer or glassy spacious quality to the upper mid-range and lower treble.  I am using the Emotiva XDA-1 DAC to drive the Mini. I always wanted a Woo like 300B based amp and the Mini just happens to be a cheaper version of it even thou it is a SS amp. As far SQ is concerned the Mini rivals my LD VI+ which is a  6AS7 based tube amp, just a different presentation to the sound.

Has anyone been able to compare the Emotiva to the TBI Millenia?
 
Also, is this guy's setup safe to use?

It seems like a cheap way to try it out with a speaker amp without having to spend a bunch of cash on the balanced cable and an adapter.

Get a Switchcraft 1230 TRS female jack for ~$10 and connect some wires to it. It has screw terminals instead of solder terminals. All you need to do is strip the wires, match them up, and screw them tight. I had some posts about it a few pages back if you're interested. 

I thought about doing the mono splitter to banana plugs thing, but the parts came out to around $30 on Amazon. Maybe you can find better prices though. You can also buy a single ended adapter from BTG Audio for a few bucks more, but then you have to wait. There's no real need to get a balanced cable though, if you are going to use the Emotiva. Balanced is necessary for amps without common ground, like the Topping T-amps.

Right, I forgot about that. I'll most likely go with the switchcraft come to think of it. Not going balanced should save me a decent bit of money as well (considering the price of the Audeze balanced cable). Do you happen to know if trying to power an LCD-2 with an Emotiva XPA-200 would be dangerous because of the extra power? Or will I be fine if I just keep the volume low?

I plugged some $20 IEMs into the Emotiva Mini-X with no resistors and they didn't blow up. So you're probably good, but I don't have any experience with that particular equipment. EDIT: you should also make sure the XPA-200 has common ground. I have no clue. 

You might want to get some resistors in there, or at least lower the digital volume in your music player. Just to increase the usable range of the volume control. Resistors will also help with the noise floor.

lolol I plugged in my $10 earbuds into my 110wpc receiver and they didn't blow up either.

I've been digging around in my desk for some old Apple earbuds I thought I had, specifically so I can try to fry them. It would please me :D

Haha, that's a good sign. I actually recently called Emotiva regarding the common ground, and it is a common ground amp.

Report your findings. I couldn't fry them with my 1 watter and fiio e17, though I made the bass distort really, really bad.
