Not me bro, only CCa I have are Heerlens.

I've had 65 & 63 , Siemens CCa, but never compared them to E188CC. However, when it comes to Heerlen, tubes. The CCa & PW version, is in another league, compared to the E188CC, in my journey.
But I'm sure others hear things differently.
Both the E188CC , and CCa, are top notch tubes.
At the moment, [@]@billerb1[/@] , has stumbled on some Valvo , E88CC , 7L4 D-getters, with excellent results, and competing with the best.


It does really boil down to preference. Conclusions will vary.

Cheers

TK16,

Have you, or someone from this thread compared the SQ between Siemens CCa, and E188CC's?

Got a general question about tube dacs and lyr amps or other tube amps in general, is it best to "match" both pieces of equipment with the same factory eg. Holland tubes for instance?, or do you guys mix and match with say Heerlens and Mullards for example?
 
Guidostrunk linked me to the tube dac anybody have it? Whats you guys opinion on the tube socket, does it look sturdy?

I have a tubed dac. I roll tubes in and out just like I did the Lyr . Matching tubes in both doesn't really matter. It takes longer to find the right tubes for me because the effects of the tubes are much more subtle than in the Lyr. One exception was tge 74 reflektors which made the dac extremely cold and analytical sounding. No musicality. Now I have old mullard ecc88s in there. I'm liking it. But I find myself gravitating towards more musical tubes for the dac. Even the suresnes and e188cc Heerlens became a little bright in there when coupled with the LC, not as much with the Lyr. So I'm saying it will be another rolling adventure . Get a dac that uses 6922s

 

[TK16]

Thanks, which dac do you have? Can you point me to some other 6922 tube dacs, does not seem to be too many of em.

 

[tvnosaint]

I use the monarchy nm24. LiteDac 60 also uses 6922. Other than that I dunno. The tube stage has more of a holographic sound than the opamp stage. The speaker line out also has tubes. A separate pair. I keep junk tubes in there for now as I'm not using it. Next month I will. You can also use it as an amp or preamp. The amp in mine requires speaker rca to hp jacks. Super clean but no bass. Partially because I have no high impedance hps. Highest are gmp 240 at 100 ohms. It's recommended for senns and beyers. Neither of which has found a place in my heart.
Like I said, it doesn't sound tubey but takes the sound profile of the tubes. Adds a little excitement to the r2r relaxed sound.

Thanks, been also considering this.

3 things that bother me are the $100 shipping, no found reviews and the vertical pcb with the tube socket. Looks kinda flimsly and not sure how many rolls that has in it. Mostly leery about the tube socket.

Post #92 @rb2013 , thinks it's pretty well built.

Thanks saw that post yesterday, probably the only non ebay hit I saw in google, gave an offer dac lite 60 have not heard back in 24 hrs, may go for the other dac, have not heard back from Rob yet about the dac 60 yet though.

Just a heads up for people here I am going to be putting up my tube collection for sale soon, about 11 pairs of tubes, lots of Russian tubes (SWGP, rockets, etc). There is lots of great tubes, I just have too many. Will probably try to sell altogether initially, if they do all sell together I will include a very nice tube box. More details to come soon.

 

[TK16]

Think I should probably do the same, even with the tube dac I just bought. I got 23 pairs of tubes not including stock lyr 2.

Good news for all of you yellow CCa lovers. Just got my octet from musculitohifi, and the tubes checkout and test really great. In fact the tubes from 1962 have the same looking print codes like the other 1962 yellow CCa that I had (bought 3 singles before from different sellers). Soo the tubes are definitely not fake.

So I currently have 11 yellow Valvo CCas ( 3 singles from before which form 1 pair and 4pairs from musculitohifi). Listening to (5,7) pair right now sounds pretty great to me and it does sound slightly different to the Yellow CCa 1962 pair made from my 3 singles. Some of these CCa pairs will definitely go for sale after I've listened to them enough!

[CFGamescape]

Looking forward to seeing what CCas you guys put up for sale!

 

[Gimpinchair]

I'd be interested in a pair when you are resdy to part with some. I've never owned any thing but the dtock tubes.

 

[TK16]

Might be interested in another set of CCa Heerlen`s, do you ship to the USA?
