Thanks Stan,
I have the AD826 in at the moment and the mod appears to make the sound a little more dramatic i.e. very quite to loud bits just leap out at you!
It certainly is not a backward step but the Caiman sounds so good anyway it is not easy to identify actual improvements.
Regards
Chris
As I mentioned :). Increased dynamic range.
The extra detail is noticeable on headphones as well. I discovered an extra instrument on a Roberta Flack track that I thought I knew very well. I had to remove the mods and then put them back just to make sure I was not imagining things.
I should have said usually rather than always:ner:Quote:

Is this what others have found with these op-amps?
Martin, I just think the AD826 has got the balance right; I have no wish to change op-amps since fitting a pair of these. Well not until something better comes along... The soundstage thing got me as well.

Was it the BB 2132 you swapped from?
Been thinking of trying opamp swapping again soon once I've given the new mods a week or so to "heat up"
No, the original LM4562. I haven't tried any others on the basis that I enjoy listening to it performing optimally rather than cooling it down and putting new components in that need more running in!Quote:

Hi Martin,
If you like the LM4562 you will like the LME49720HA. This was the best that I had tried. I have the AD826 in now and really like it but yes the bass is boardering too heavy although tunefull.
The wire mod that Stan suggested helps with the AD826 though (adds a bit more control to the bass).

One of the mods that I haven't been able to yet publish is the passive mod:ner:. The main reason for that is that I was waiting for a couple of 47uF Rubycon caps from someone. The 2nd reason is that I have to double check it on my integrated amp since it has been a while since I last tried it. My amp is in storage right now whilst the builders expand my workshop/lab. But hopefully I can show the mod off in July:eyebrows:.
Ha ha, that reminds me. Did you get the caps ok then? :lol:Quote:
