Are those Auricaps replacing the little yellow block ones?

 

[zkool448]

That's right smeggy (C4L, C4R).

Hmm, does it actually make any difference I wonder.

 

[DoYouRight]

This is going to be my bedside rig's Tubey I think. Thanks for all the great tweaking info and Ill post what I develop over my course

That question has launched a Thousand Cap Purchases my friend - if you can hear the differences in sound between tubes, chances are you can hear Cap differences as well...

BTW - I have the 6n6 back in my work rig, (but with the Grados.) Very peppy...

Might I ask which your favorite tubes are when listening with the RS-1s?

I've definitly not decided yet, because I'm stuck with an imbalance in the soundstage, trying using matched transistors.

I did wonder as I know going undersize on output caps can quench bass a bit, but I have no idea what these ones do or are for. I might try something though, just because..

For these interstage coupling caps I think we are all sticking w/design value 0.22uf & rated 100v or better. So we aren't talking size WRT the cap's value like you might for amps w/large output capacitors on their outputs (to block DC).

I think we can agree, maybe, that the effects of various coupling caps is more subtle than that of various tubes. And you must watch "wearing out" coupling cap pads / traces when rolling them. I think the WIMA upgrade caps are easiest to deal with.

I could do what I did on the other cap and just parallel though that may defeat the purpose of the better caps. The one at the back was same make/type but bigger so no biggie there.

I'm just looking to get the very best from this little treasure. I really like this amp.

 

[wiatrob]

Smeggy,

Probably not the best idea to parallel caps in the audio path (especially disparate types.) If you want to hear the difference a cap makes, my loaner amp has socketed coupling caps. I'll swap you your K1000s for a month and you can cap roll to your heart's content

cfCubed is right about the caps - probably more subtle sound diffs. And you can get a whole bunch of tubes for the price of some esoteric audio caps.

Two resources sited a bit about caps:

Maybe not the best segway into my post...

I've been won over by the Auricaps. I was very skeptical; I expected to be hard pressed to nail down any real difference between these two. I mean both are very well respected caps.

Listening to 'inamorata and narration by conrad roberts' the trumpet had a richer and more full sound with the Auricaps that really brought it to life. The drums too felt more real, with a sharper attack and very nice timbre. I equate this to some midrange emphasis happening with the Auricaps. But, wow, does it sound great.

Strangely, not only was the midrange nicer but the top end was more extended and detailed (like very obviously so). Listening to such a complex track the superior instrument separation of the Auricaps was also clearly apparent.

Like I said, I'm won over, and I'll be ordering a pair of Auricaps for my own CTH tomorrow.

I should mention I was using a 6DJ8 for most of this comparison, and swapped the same tube back and forth between the amps.

 

[smeggy]

heh, I'm not into exotic or esoteric. I'm skeptical at best on such things

As to the K1k, you can borrow them after sachu has finished with them

RDS,
how much are those Auricap things, dare I ask?

about $12 each

 

[smeggy]

Oh, not too bad, I recalled mundorfs being about $30 each!

Bad sachu, bad!!
