Technical Details

  • Brand Name: Music Hall
  • Model Number: PH25.2

Product Description

Marrying a gorgeous sounding tube pre-amp with solid-state amplification has been a technique for achieving unequaled sound quality in hi-end component audio since the advent of the transistor. While kicking around ideas for our new headphone amp we thought, why not try this same technique in a single component? We built one up and were blown away by the increased detail, clarity, and presence the design offered. The tube hybrid headphone amp was born. Hand assembled using the highest quality parts available the music hall ph25.2 will have you singing along with your favorite artists.

As background I have owned the Grado battery powered amp, the Headroom powered Micro amp before recently acquiring the Music Hall 25.2 headphone amp.
I have owned many headphones in the past although today its not a passion. My favorite was the Stax SR-5, right now I have just Grado SR-80's and Koss Porta Pros.
Overall the Music Hall did what I wanted, it gave that sweet tube sound with guts, things that ultimately led me to part with the earlier headphone amps. However the control of the earspeaker seems more problematic with a grittiness in loud passages using the Grado that suggests matching headphones may be more problematic than it was with the Headroom Micro amp. Same grittiness was not heard with the Porta Pro and the Mh25.2, although the Porta pro is not as detailed as the Grado. So my overall recommendation with this amp is to try to audition headphones with it before buying and buy headphones that are well behaved under the current this amp is capable of generating. This will probably be my jump off point to support buying Hifiman or Audeze phones.

Bought this headphone amp for driving several different headphones like Ultrasone Pro900, Sennheiser HD-650, and Denon AHD 5000. This amp has plenty of power and sounds great. Tube amps like this one just sound more analog than solid state amps.

I was recommended this for the grado 325is that I have. It's kind of more vacuum-like than directly tube-like, they're very small tubes which aren't 12au7's or 12ax7's, but tiny plastic things. I only listened for up to two to three days and kept looking for the sound which I wanted to hear in my head. While the soundstage is much bigger than my pro ject headbox s, that wonderful grainy, edgy sound which realistically portrays the music (I would say neutral) was not there. I found the music hall headphone amp to be EXTREMELY BRIGHT. I know that components change after burn-in, and this one supposedly requires 200 hours(!), but I've never heard of a sound signature changing, or the timbre. I would say the sound was colored (don't trust me on this, I've never tried to use terms like this before) because again, while the soundstage was bigger (why I spent the money on a better headphone amp) the sound was nasally, not at all realistic. I think it's good to compare a headphone amp to your speakers (if they're good ones), or simply go looking for the kind of sound you want (playing around in your head all the time). The music hall did not sound at all like my speakers--polk rta 11ts; no neutrality, wide open soundstage, but instruments not portrayed realistically; a plastic, compressed sound, quite dry, VERY bright.

Now, I know what you're saying: the grado 325is are INFAMOUSLY bright. Not true, the pro ject headbox s was very neutral with great power, and played my 325is to perfection, never seeming bright. The 325is are trebly, as in they have a lot of strong treble that's not entirely smooth but a bit hard, they really only handle mids and some very low lows the best, not highs. Harsh highs is not brightness, there's a distinct difference between the two.
