I think you're better off going with the Little Dot MKII or MKIII for the HD600 since the I+ is optimized for low resistance headphones and not high resistance headphones such as the HD600.

I bought an OPA2604, put it in the buffer slot of my STX and it made the lower treble really harsh, I thought this couldn't be right so I tried putting it into my Little Dot I+ and BAM warm, liquid sound with no harshness, I later read that this opamp can be harsh if it's not fully powered, I...

I just tried switching out the LM4562 with the LT1364 in the buffer and keeping the stock JRC's in the IV, bad combo with my AD900's, the vocals were brought out too much especially the male vocals, there was extreme sibilance in the male vocals, I had to put the stock LM4562 back after just an...

I got the M8161, I was disappointed in them at first because they were less detailed and the soundstage wasn't as wide as the stock tubes but then about 15 hours in something weird happened, out of nowhere they started sounding really warm and bassy, the transition was almost instant, it was the...

You were right Robo, the 2228 isn't that great in the buffer slot, this morning I put the stock LM4562 back in the STX buffer and swapped out the stock opamp in my little dot I+ with the 2228, I gained at least 3 times the bass with the 2228 in my little dot than when I had it in the STX's...

Quote: Originally Posted by ROBSCIX Careful, don't wash out the sound.... The 2227 like the 2228 are known to be bassy, so if you put that in the buffer it will roll off much of the high end produced by the I/V section. If you put bassy opamps in the I/V you can get a totally washed out...

I just replaced the stock LM4562 buffer with the OPA2228, the most noticeable change is the treble has been tuned down quite a bit, the vocals also sound a tiny bit further back, the bass has increased very small amount but it's only noticeable on certain songs, all of this characteristics are...

I have the AD900 and I need suggestions for an opamp combo that will increase the detail without sacrificing bass quality or quantity (a slight boost in bass would be fine too) of the stock opamps, I'm willing to sacrifice a little treble since the AD900 are fairly bright cans. Thanks.

I agree with the OP, I recently upgraded from onboard ALC889a to a Xonar DX, I'd say I noticed only a 2-5% increase in SQ depending on the song, I'm not under exaggerating here either, for $80 I expected a lot more. The difference is comparable to a properly encoded 320kbps mp3 vs FLAC or...

I'd get a pair of Audioengine A2's, they blow any Logitechs out of the water, they have built in amplifiers so you don't have to worry about buying an amp, these things have a 0.05% distortion rate, Logitechs have 5-10%. The price is pretty steep however $200, but you can find refurb/used...

I've had my AD900's for a month now, I gotta admit at first I didn't like them, I missed the bass impact of my A700's, but after about a week I started noticing things in my music that I haven't noticed with my A700's now my A700's get no head time unless I need isolation, they really grew on...

It's something I didn't really notice until I bought the AD900's, I always blamed it on the recording before that.

Hi there, long time lurker first timer poster here. I love the sound signature of my A700's I think they compliment my AD900's very well, however I have one major gripe with them and that's that male vocals are very sibilant and mechanical sounding, I read that the A900's share the same sound...
