Caiman Mods

[bergdus]

Thanks Martin,

That's 30 between the two of us, so we only need another 6 to complete the orders.

Does anyone else have any left over?

I've got 10 rubycons left, so if needed

I am looking for a couple more to try on the TC-7510 and see if it also benefits from doing the MOD21 with the Rubycon. SO I might be in the market for a few extra one's myself.

As I offered spare caps towards group buy cause, Dave has a first choice. If there are any left you can have them Stan. Also have some 10 x 33uf16v left which were ordered by mistake.

The Murata's have been in since Saturday and sounding good. The biggest change I have found is the clarity or the "pure" sound as I keep saying. Depth of the image is also better and not so much in yer face as per the Naim style.

I like the changes and well worth the £20.00 or so to do (I had done the Rubycon's a few weeks ago).

Please bear in mind I am using a purposely built linear supply set at 15v so may be different if using the SMPS. Also got the standard LM4562NA's in as well.

Im trying out this

and the same for OP627, not sure what to expect, I`ll let people know.

Don't see why people like the 4562, I really don't like it much at all, the mids are pretty great, but the bass sounds pretty bad and the highs sound too sharp..imo.
Had AD826NZ or something in before and they were pretty good

I think mileage varies considerably with op-amps depending on your digital source. Gaz hit the nail on the head when he mentioned the other day that he thought the changes in regs and caps would kick off people experimenting with different op-amps again.

Up until last week, I agreed with what you have just said Shane. I used to find the 4562's very "boom and tizz" and not very refined, a bit fatiguing on extended listening too. I think that's why I preferred my 7510 with the op-amps removed over my Caiman with op-amps, but that was from the optical output from the Mac.

Now however, with the HiFace feeding the DAC instead of the Mac's optical port, the 4562's are back on top and the 7510 has been shown the door from the main system. Compared to before, the bass is well controlled and has much more texture and tune and the treble is clean and sweet.

I've not even performed the regulator upgrades yet, so I think this just illustrates how poor the optical out from the Mac actually is (at very least on 2007/8 models). This is something I have suspected for a long time.

hmm well I`m using USB connection from my Windows PC into the caiman, so perhaps jitter could be the issue here. I have been meaning to order a hiface, but they are out until early March grr unless anyone has one they wish to sell or better yet modded/mod and sell to me :P??

[Gazjam]

What's this hiface you chaps speak of?

[smurfbrain]

Hiface is a 24/192k USB to spdif converter price around £100

Makes for a really good transport I read, which seems to make a big difference for the Caiman, but I am dubious until i hear for myself
