HR Micro vs. HR Ultra Micro amp for iPod Touch

[Stefaan]

Hi, new to this forum and really, it's already too late for any of the head-fi virus warnings

Here's my situation: I'm getting an iPod Touch and I'm looking for advice to get the best sound possible out of it, I already have the HD-650 cans and the SAA Equinox cable is on its way. I'm also getting a Qables Silvercable LOD so you know my setup.

As it is a portable player I could take the portable Micro, but when walking or cycling I won't be using an amp nor will I use the HD-650's but just some mediocre IEM's, I find it rather impossible to do some serious listening in a busy street so I'm not really spending money there. So no real need for a battery- powered amp.
I like the design and small footprint of the Micro Line and based on some reviews of the earlier models I think I can't go wrong with HeadRoom. So that leaves me with two options:

the 2007 Micro amp and the 2007 Ultra Micro amp.

What I was wondering is how important the source is, I think the amp will almost constantly be used with the Touch so I wonder if the extra 300$ for the Ultra will be heard with such a 'weak' source?

Thanks!

I'd like to know this as well, but I suppose the only way to find out is to audition both. As far as I can tell from the information on the website, the chief difference between the two seems to be the OPA627 in the ultra amp. I wonder if there is a real quantifiable difference between these two products? My gut says yes. There has to be some reason why HR would make a considerably more expensive product. And there has to be an even better reason why people would buy it.

Source is always important. The Ultra will just be an expensive way to discover how bad our iPods really sound. If having battery power isn't important to you I would say just get the regular Micro, especially if you aren't going to be using high end 'phones.

I too am thinking of getting a new amp or two. I wouldn't get an Ultra unless I was going to replace the Headroom Desktop in my bedside rig. I have a decent Sony SACD player in there as a source so I think that would be worth the money if I did it.

If I can bring myself to wait the four to eight weeks for one, I would get a Portable Micro to use with either of my iPods.

If you have the extra $300 I'd say go for it. I have the Ultra Micro and the entire range is very punchy crisp and detailed while remaining smooth and not harsh. I haven't heard the regular micro but I will say that if you do go with the ultra you won't be disappointed.
