HE-500, LCD2, D5000, DT770, SR80, on a speaker amp (Emotiva mini-X A-100) Project - Page 149

Ive been curious about that combo MONTHS ago! Koiloco, I think you and Modulor remember when I mentioned that in an old PM! Only thing that seemed questionable was the impedance matching with the two amps. I REALLY want to know how this would work.

By the way, I emailed Emotiva and got a response on the input impedance of the MiniX. It's around 10K ohms. Thus an OTL amp like the Crack works best in lieu of a dedicated preamp.

Oh. My. God. THIS ACTUALLY MIGHT WORK!!!! Yessssss! That makes me happy. Let's just hope it keeps a somewhat lively sound to it that people seem to give it. I can just imagine. The tube preamp with the Emotiva. "The next best thing" for the HE-500

Wow as head-fiers I don't think we realize what we've gotten ourselves into here. After some more research, it seems the tube preamp/solid state speaker amp is a cheaper way to get the tube sound into a speaker system. Apparently powerful tube speaker amps are very pricy, so it's more economical to get your tube sound from the preamp and just get all your power from the solid state speaker amp. I happen to have a tube speaker amp, albeit a weak 10W one (though wattage between tube and SS are different for speaker amps, tube plays louder at same wattage). Went ahead and connected Crack with it. It's kinda late here and I'm getting tired, so I can't really pick out the exact signatures, but it sure sounds good! I do notice a lot more sub-bass. One drawback is a higher noise floor, where in speakers it probably wouldn't matter, but here I can definitely hear it in between songs. Will have to give a more thorough review tomorrow.

My Emotiva Mini Arrived this morning, was shipped on the 31st Oct, must say I'm impressed. No issues atm, slight hiss, but not as bad as my other model!

 

Well done Emotiva :)

Nice, want to have a Emotiva mini X A-100 too but first I need to purchase a mid-fi headphone first, Alpha Dog maybe.

post #2227 of 3793

That is one drawback of using tubes to drive the Mini that you may have a higher noise floor from the tubes. I sometimes will hear some noise from my tube pre-amps depending on the tubes that I am using. Generally tubes amps do not have as good of a S/N as compared to SS amps. The trigger inputs came in handy when I am using the Emotiva XDA-1 remote to turn on both the DAC and the Mini at the same time without any pops being heard thru the headphones. The same when I turn off the equipment no pops at all thru the headphones just the output power relay clicking on the amp. The muting power relay on the Mini works much better that the Schiit Lyr I have.

Why have none of us thought to use a tube preamp to speaker amp this whole time? lol. It definitely would solve some warmth issues on some amps.

 

I might try my Bravo or incoming Aune T1 this way if they have line out. Need to check.

post #2229 of 3793
For me I didn't make this realization until I got into speakers and wanted a warmer sound. For some reason without that speaker mindset the idea of a preamp never popped into my head smily_headphones1.gif
post #2230 of 3793
I don't even know how me and my cousin thought of the idea. It was just kind of a given solution to having a tube sound without a dedicated tube amp...

I think most people are religiously against double amping until you take a step back and realize this is a speaker amp.

I and modulor have talking in PM for a while about getting a tube DAC to achieve this goal but neither of us carried it out.

You guys know Bottlehead is making a tube dac right?

I read about it but haven't checked it out yet.  Promising?

post #2235 of 3793
So basically, I've tried listening to the he500 on my new emotiva and I've noticed a barely audible hiss. Also, I am hearing some sibilance. Is this normal or am I just extra sensitive to sibilance? If I were to use the o2 as a preamp would it reduce it?
