Comparison of HeadRoom Amp + DAC combos

It all boils down to money. If you have it get the desktop with the home amp and the hom dac. However you will have to add the large P/S.

The Micro (desktop) stack will have 99% of the sound of the Desktop with Desktop Module and DAC. The desktop has slightly better PS regulation and components, but otherwise will basically sound the same as the micro combination. The sweet spot in the desktop line IMO is the Maxed out version, but that's just because it sounds so damn good...

Anyway, sounds like you're a prime candidate for the micro DAC.

With a Desktop Power Supply, the difference will be most noticeable. Otherwise, it is a small difference. And remember that the DPS can just as well be used to greatly improve the sound of the micro stack too...

I'd still say the micro DAC is your best option. The Home DAC improves upon the the Desktop DAC/Micro DAC by putting OPA627's in the audio chain, but unless you are feeding that into more OPA627's in a Max Module, I'd say you aren't getting the best out of it. The Micro DAC is still the best $299 DAC you're gonna hear.

FWIW, rpaul -- that's exactly what I just did. Recently bought the Micro with desktop module to use as my portable setup with my iPod, loved the sound and decided to "go for it' by re-ripping all of my music and adding the micro DAC to my setup.

Just got the DAC the other day, the combo sounds wonderful.

Enjoy,

There's no other USB Dac out there of this high quality at this price point.

Hey rpaul,

I was on the road this weekend (but I did bring along the Micro Stack ), so I haven't had a chance to empirically test for differences. Listening to the 192kbs mp3s off my laptop via my new setup immediately exposed the limitations of those rips. No surprise.

My current plan is to re-rip to lossless (prob Apple lossless) to archive all of my music...my Micro Amp + DAC will spend most of it's time hooked up to the optical output of my G5 and will use the lossless files for playback. I will then test several levels of AAC encoding to re-populate my iPod.

Headphones are a pair of Sennheiser 580s at home (sometimes my husband's Grado 80's) and Etymotic ER6s while traveling (will probably replace with ER4p/s soon).

I think I made an excellent choice and ended up with some very versatile hardware (thanks to the guys here). And hey, my wallet is lighter, but not on life-support!

best,

JT

Re-ripping to Apple Lossless will give you a significant soinic upgrade. You should consider loading your iPod with lossless files too. It holds less, but sounds much better.

Yeah, that definitely crossed my mind but will require a bigger iPod (80 GB versions are rumored to be out soon) ....YIKES, more $$

JT

There's gonna be no going back - to the iPod, or to lossy files...

That Micro DAC is going to give you a taste of what a real source can do for your system. Headroom have done an amazing job with their DAC's. It really puts so many other makers to shame that this relatively small bunch of people can, with some thought and expertise, put together this kind of sound and feature set at an unheard of price point (remember they've never built a DAC before...). As far as I'm concerned, the $399 extra Max DAC competes with multi-thousand dollar CD players.

Anyway, you're gonna love it! I'm getting some Headroom lovin' as I write this, and it still puts a smile on my face.

Hello. I'm relatively new to the hi-end headphone world, and quite honestly amazed to see the products out there in the amp space. I never even knew a dedicated headphone amp existed until a few weeks ago! But after coming to the conclusion after several configuration changes that I just couldn't get myself to a happy state with my 2-channel audio setup in the small room that my wife will let me use for it ( ), I sold the Polks, sold the Harman Kardon, and set sail for can-land.

I got a pair of brand new Senn 650's on eBay for $300, I was pretty psyched for that number after shopping around a bit. My Cardas cable should be here any day.

I started off thinking I'd go with a Total Bithead for my iPod and/or laptop, but quickly decided I wanted to go with better SQ and was willing to sacrifice portability. So I ordered the Micro Amp (Desktop module)/Micro DAC, which should arrive tomorrow. I have a large FLAC collection that I will pump through the USB hookup.

I'm thinking that unless the Micro stack completely blows me away, I might just upgrade next year to the Desktop line and max it out with the upgrades, but I'm not prepared to drop that much coin..... yet.....

What I'm wondering is - how much of a difference would the Desktop Power Supply make to the Micro Stack, as someone mentioned earlier. If I do decide to upgrade, I will need it anyway, so I guess the only issue is how much of an improvement it will make for the Micro Stack. I guess the question is a little silly, because I can always try it and return it if I don't feel it's worth it. But I'd rather know up front if people think it would really be worth it, so I don't end up wasting the good folks' time at HeadRoom.

The Micro Stack package is $600, the Desktop Power Supply is another $400. Will the difference really be worth adding another 66% onto the cost???

Thanks in advance!

Neil

It's very difficult to say whether an upgrade is 'worth' something or not. It depends what it means to you. The power supply will offer a small difference in sound, generally giving more detailed and controlled bass, and a more accurate soundstage. You will hear less harshness in the treble too.

But these differences are much smaller than for example the difference between one amp and a completely different one, and if you aren't convinced by the sound of the amp you have, the DPS isn't likely to change that. If you really like the sound of your Micro Stack and want to get the very best out of it, then yes, the DPS is the only way to improve it, and you will know that it couldn't possibly sound any better. I would however advise against getting it if you plan on changing to a completely difference system in 1 year. You may want to get a Home by that point, or an amp from a completely different manufacturer. I use a Maxed out Desktop with DPS and am amazed by it in every way, and have absolutely no intention of changing to another amp in the foreseeable future. If I didn't intend to keep it for the long haul, I would have kept on using the BS1 power supply which is almost as good (but not quite) as the DPS.

I recommend you send an e-mail to headroom and ask. They will probably steer you away from the DPS. They are very honest in that respect, and admit that there are more important upgrades to spend one's money on at your stage than power supplies. They will also describe better than I can what the potential benefits are.
