The question is.. Topping TP60 or emotiva mini-x with the emo being slightly more expensive..

Crisp, clean, powerful sound......the Emotiva justs grabs your brain and takes it for a powerful ride, sounding absolutely superb throughout.

I was enjoying my AKG K712 Pro with the Lyr more than the HE-500 and that had me really wondering about how good they really were.

My doubts are completely erased. HE-500 is stellar, they obviously crave gobs of power. I'm driving them like a Banshee and they are responding well beyond my expectations. Highly recommend the mini.....thanks Mal for posting such an awesome spot on experience!

 

+1

 

Emotiva is clearly better than the Lyr for the HE-500.

Add another to the mix:

 

SMSL SA-50 $65 50W per channel. Most likely a Class D amp, and not a Class T.

http://www.amazon.com/SMSL-TDA7492-Integrated-Tripath-Amplifier/dp/B00F0H8TOC/ref=sr_1_2?s=electronics&ie=UTF8&qid=1382840893&sr=1-2

 

I have an SMSL sApII pro which works very well, and even does pretty decent with the HE-500 (1W at 32ohm). The size of the SA-50 is much more manageable on my desk than the not so Mini-X.

 

I also have the Mini-X on the way too. I didn't want to miss out on the $169 price.

 

The 100Wx2 Lepai has too high of a noise floor, and I don't want to mess with the gain internally.

 

I'm hoping to find a cheaper, smaller, similar sounding amp to the Mini-X. The mini might just be too good of a match with the HE-500 though.

I've seen that SMSL has a few T-Amps and a variety of other cost-efficient stuff that's fairly compact.

I'm liking the sApII Pro a lot. I like it better than the Magni, despite the II being slightly less powerful.

 

The other T amps they have might be great too, and I just might try one. I really like having tone controls on my current Lepai though.

 

The SA-98 has the same amp as the Lepai LP7498E, so I would probably get the same noise floor and hiss if I tried that one.

Great to hear!  Please give us your honest impression when you have the chance to compare the Emo to other economical amps.  While I am skeptical about Lepai and Topping, I haven't heard them so I reserve my judgement though I often wonder what can you manufacture with so little $.  :beerchug:

I haven't listened to my HE-400 for quite awhile but gave them a try tonight with the min-X.

 

They work perfectly fine, but after 9 o'clock, things are getting uncomfortably loud. Also, they seem un-naturally treble-centric and the bass not as controlled as HE-500. Looks like it's time for the 400 to go bye-bye.

post #2048 of 3639

damn I might try again he-500 on emotiva and since he-4 is pretty close to he-6 might stay with he-4/he-500 combo having two very different sounding HP depending on mood or being bored with one

 

for the SMSL stuff I got some amps in the past and I found some design flaws after having issues with it, I would be very careful with ultra cheap chinese stuff on ebay If I were you, also had some chinese dacs and there was the same story - totally wrong calculated resistors (clipping), and when I opened it up it showed ridiculous assembly errors - nothing in common with the photos of the inside presented on ebays auction - I guess quality control just doesn't exist, so be careful, my personal advice (however many times I got my money back, but still this is not funny story and you might damage your expensive equipment)

I don't know if it's been discussed in this thread but because the Emotiva mini-X has common ground output (left and right channel negative speaker terminals connected to ground) it is a single ended amp and there is absolutely no benefit to using headphones wired for balanced operation. Grounding the negative terminals feeds the headphone cable with different impedance to the + and - headphone wires so there is no common mode noise rejection. If you use an unshielded balanced headphone cable with the mini-X you've effectively turned your headphone cable into an antenna.

 

Since the mini-X is a single ended amp there's no need to convert to balanced headphone wiring so you can use a simple to make female TRS speaker terminal to headphone adapter cable as I described above. You should also use a shielded headphone cable whether you use a single ended or balanced headphone cable.

 

If you want a solid state push-pull truly balanced output amplifier to drive your balanced headphones take a look at the Tripath TA2024 based amps like the $89 Topping TP-10. They sound fantastic. Their only downside is they are true push-pull amps so they cannot be used for single ended output--you cannot directly connect the right and left negative speaker terminals to a TRS plug. The SMSL SA-50 $65 50W per channel mentioned above is also a balanced push-pull amp.

 

Beware though not all Tripath amp chips are balanced push-pull. The TA2022 has single ended common ground output and there could be more.

I just think the distortion tend to be pretty high on those tripaths

The HE500s runs no worries off the TP60 without resistors. Unfortunately there aren't very many TP60 users to tell you how good it is at driving Hifiman cans like there is with the mini-x. I've been told by others it drives the HE6s great so the HE500s wouldn't be an issue.

I actually bought the TP60 in frustration because I lost out on a Tbi millenia for about the same price on eBay by 1 buck. It's still the best $211 I've ever spent.

The best thing about the TP60 is the amount of detail it can present to you. Anyway, I'm not going to say more. There's hardly anyone around with this yo back my claims anyway.

I don't hear distortion until I max the volume pot and that is ear splitting

Only at high volume. I'm only at 9 to 10 o'clock for max volume with my HE-500s.

post #2054 of 3639

I've regretted for a couple of months not pulling the trigger on the mini-x when it was on sale for $150, but I'm all over it this time.  Just ordered and can't wait for it to get here so I can try it out with my HE-500s.

robrob,

 

I've been very happy with my Topping TP-10/HE-500 combo.  Really sounds good and opens up the sound stage of my HE-500s.  I'm really excited to compare to the mini-x.  Anyway, just wondering if you, or anyone using a class T, are using resistors across the output terminals?

 

I currently have 8ohm non-inductive resistors in parallel with my phones, but I'm not sure if it's necessary or ideal?  I had read somewhere that tripaths need an load impedence of 4-8 ohms for optimal performance.

post #2055 of 3639

I have my HE-500s connected directly to the Tripath amp with no resistors and I'm very happy with the sound. It could be that it would sound even better with resistors though. I only use about 40% of the volume knob so there's definitely enough power to handle resistors.

 

I have not listened to an Emotiva mini-X and I'm not claiming my $18 Tripath balanced push-pull amp board sounds better than the mini-X (but it might ;) ). I just want to make people aware of the mini-X's single ended output and its effect on unshielded balanced headphone cables.
