I bought a used MAD Ear+ last week and received it on Thursday. I’ve been using it a lot with my RS1is and thought I’d pop in with some impressions.
This is an older model with only one headphone output. My DAC is the Emotiva DC-1 and I have some brief comparisons with the headphone amp built into that unit. I am using stock tubes in the Ear+
The things that stuck out for me:
The mid bass on the Ear+ is slightly more rounded and a little heavier than the DC-1 headphone output. so there’s a bit more weight to cellos, bass guitars, etc. I don’t really notice a difference in bass kick, though. Depending on one’s viewpoint, you could call the DC-1 output thinner or simply more flat. I know that with the RS1i, I prefer the sound down low with the Ear+. I can’t notice a difference in detail down here, though.
The highs are less piercing on the Ear+. They’re not quieter, exactly, but that edginess of the RS1i is softened on the Ear+. It’s still aggressive but hotly mastered tracks are worse, to my ear, on the DC-1.
The kicker -and what makes me appreciate the Ear+ - is that I notice is greater clarity and three dimensionality with the Ear+. For example, I was listening to a song with a lot of crashing, rolling cymbals and the difference between the two headlamps was that, on the DC-1, they sounded papery and slightly one-note. All I heard was the high frequency tizzing. But on the Ear+, it was possible to hear some more subtle, lower frequency notes underneath the crashing, giving the cymbals more body and dimensionality.
I’m not saying I hear the same thing across all frequencies - my ears and source material may not be good enough - but for any vocals and instruments with a lot of HF information, I found the Ear+ presented them with more realism as I could hear more subtle notes under them. And this, in turn, makes entire tracks sound more lifelike and a little better imaging.
For my ears and my brain, it’s not a night and day difference. Some other people might say it is since standards are different for everyone. But I do think the Ear+ is better than the DC-1 headphone out and it really does gel quite nicely with the RS1i’s natural sound.
I’m glad I have the Ear+ and RS1i combo. It makes the RS1i sound about as good as I’ve heard it - I’ve had one in the past and used it with a variety of amps so the DC-1 isn’t my sole reference point - and I’m looking forward to buying a few tubes to replace the main Sovtek.
