Which opamp did you go for?

post #107 of 2170
The stock 209. After reading through the UHA4 thread and reading about how Anaxilus thinks it's the most neutral and detailed sounding Opamp, it was a no brainer. I don't want to affect the sound of the ES5 if I can help it. I just want a touch more clarity through the midrange and a better sound stage.

Good to see the few people who have bought this amp are really enjoying it. I'm surprised more people aren't jumping on this amp considering how expensive other offerings are. Hey lee once you get around to rolling opamps let us know how easy/hard it was to get into the case and yank/insert the chips.

Until I get the appropriate tool to take the OP-Amp out I won't be doing the switch. I'm currently burning in my unit and loving the sound so far. I'm generally for finding balance and not overdoing things and I have a suspicion still that using the 209 will exactly do that but we shall see ;). Anyways I am enjoying how the AKG3003 sounds so far. My ears agree with anaxilous on this one though and I prefer the Hi-filter on as it brings the vocal range in the position I feel they should be in. With the reference filters the vocals are kind of in the background hiding behind the treble a bit. Although on some recording you can get sibilance (this is due to the recording though IMO). Currently using the AKGs with the UHA6 MKII, DACport LX and cPlay (Asio bit for bit).

@lee730, I'm confused when you say that about the opa209.  The added transparency it gives doesn't make it brighter; rather it gives it a blacker background and (IMO) a more 3D soundstage, in effect making it more resolving.  Are you thinking the 209 will make it brighter or more analytical in the treble? Just trying to understand; you got the 209 as an extra right?  Looking forward to your comparison here.

Yeah that is what I was worried about, it becoming brighter and more fatiguing. A fellow headfier I've been in communication with opted for the 209 amp on a recommendation (he originally had the 8610 in his UHA4). He ended up hating it and said it became fatiguing and thin compared to the 8610 he was accustomed to (which he considers more euphoric and engaging). Don't get me wrong I do love clarity but not when it's overdone.

 

To hopefully give you a better understanding of what I mean. When I had my UHA4 and compared it with my O2 amp. I got more musical enjoyment from the UHA4 and I also noticed more things in the songs than I did on the O2 for some strange reason. It just drew my attention more to it. The O2 on the other hand is very clean and the background is black, but the amp does get fatiguing for me with long listening sessions and that is one reason why it's not my favorite. The transparency is boarder-line for me and I'm worried that the 209 will be too much. Does that make any sense to you Shane?

Yes, I think I understand better. I think you'll e pleasantly surprised then. The O2 has a more aggressive, upfront sound, which I like too but it's different from the leckerton.

I've had a chance to listen more with my UHA-6S MK2 on a few setups and now have a bit better idea of how the sound works and changes from straight out from my computers (I do use it exclusively with my laptop and desktop).

 

Battery:

So the battery says about 8 hours or so. I'd say that's a pretty accurate. I've found I get about a day and a half's varied use out of it. I'm pretty good about turning my electronics off and on as necessary. I haven't gone and tried to run it down from full to empty but I do think you could get a solid day's use out of it. It also appears to charge pretty quickly and, for those curious, if you plug in both a TOSLINK cable and the USB cable it will use the TOSLINK for audio and the USB for power (which I was quite pleased to discover).

 

Sound Signature:

I went with the default 209 because I was looking for something that wouldn't alter the sound I get form my headphones, just sort of improve it. My main listening headphones are my Heir Audio 4.A's but I also used it with my Denon AH-D2000's as well as my Acoustic Energy Aego M speakers (just for the hell of it).

 

Over-all I found that I lost some of the depth from my 4.A's but that for that I had more detail and better presentation. I also gained more on the high-end, which helped open-up the sound quite a bit. However, the highs didn't become too bright but instead just felt like they had room to breath. In fact the entire sound seemed to smooth out and open up, which I quite like. It did take away a bit of the "excitement" from the sound of my Denons but for that I gained better sound quality.

 

Also, I found the low gain setting was good enough to power my 4.A's very well and my Denon's quite well. I imagine there's enough power coming out of this AMP on high gain to power a good variety of headphones.

 

One other note about the sound-stage, I found the 4.A to have a very good soundstage to begin with but this really opens it up. I've mentioned this before that my test for sound-stage isn't music but, instead, is gaming simply because games are designed to have accurate, clear directionality in a way that mimics how you actually hear things. I found that this UHA-6S MKII really helped open up the sound stage and really improved directionality for me. I could often hear exactly where opponents and teammates where, which is really handy (for obvious reasons). In this sense I'd say it passed with flying colors.

 

Issues:

I don't know if this is due to the cable I'm using or the device itself but if I shift the cable much I get feedback on the line. It appears to be at the point where the cable meets the AMP but I'm not sure if the issue is I have a cheaper cable or if it's an issue with the device. I'd be willing to try another cable if anyone has any suggestions. My only requirement is that one end be an optical headphone plug such as might be used on an iMac.

 

I also get a bit of noise, even on low gain. It's not much and certainly not enough that I hear it when I'm playing music, but it is audible when nothing is playing.

Thanks a lot Doug I've updated the threads title and added your impressions to post #1

post #115 of 2170

sorry for the newbie question, is there a comparison (review) how diff Amp (209/627/8610/797)?

 

from what I read so far, 209 amp is neutral, 8610 is more bassy? how abt the rest ?

 

thanks

8610 is slightly warmer and has emphasis on the mid-range.

The 8610 is the default op amp used on the smaller UHA-4. I own the UHA-4 with that op amp setup and I agree with lee730 on his statement. It also has a neutral sound but it's just slightly warm and because of it's slight warmth it sounds a bit fuller on the bottom frequencies. I had a chance to do a comparison against a fellow head-fiers iBasso D10 Cobra and my UHA-4 had fuller sounding bass.

Just put an order for 1.  Hopefully it has good synergy with my 8.A which is coming sometime soon (I hope)

Works well with my 4.A (went with the 209) so I have high hopes!
