So what do you think of the Mazda's?

Funny you should ask (timing-wise). Was very pleased with the initial install in the T-8 here in the office system. Wider, fuller soundstage, more bass oomph, less edge on the high end (speakers Dahlquist DCM-7s). Haven't gotten to changes in the Ultras yet. But have been experiencing some fuzzing with the 1st set. Not sure if it's dust on the switches, dials, have pushed & rotated and that cleaned things up for a bit. However, as I was reading the latest posts, saw yours, and was having more fuzz I thought, well- let's try the other set. Currently everything sounds fine, no fuzzing on the same CD that was playing earlier.

Guess I'd better make the effort to swap things around more in the next day or so, make sure if I had one go bad I can exchange it before the time runs out. They were tested by Upscale, and they put info on the box, but not sure what it means in the 'big picture'. I paired the ones that noted T-1:5900 T-2:5500 with T-1 :5500 T-2: 5700. The other set notes T-1:5100 T-2:5700 & T-1:5200 T-2:5700. I had one of the 6N1Ps go bad in the T-8 on setup, which Frank was most generous enough to replace even though that's not normal practice. Just kind of my luck on things as often as not. Think I'll drop them a note, get some education.

Bottom-line, while I liked the 6N1Ps, I like the Mazdas better in this system. Need to test the Ultra system with the STs, would expect I'd like them even more there, we'll see. ELP's 1st is sounding amazingly full, sweet, & dynamic at the moment.  :eyebrows:

Dual triode, that's you're T-1 and T-2 measurements. Sounds more like dirt to me, but I'm sitting here at a computer.........

Thanks for the input, I'd browsed their website and couldn't find anything that clarified it. Have found what appears to be a good info link on tubes for homework, so I'm not a total boob, or newb in that regard. And yes, dirt was my 1st thought. Of course the only dial I didn't blow off & turn was the source selector, which appears to have been the problem (now resolved). Should have realized it as there was no problem on the tuner source, but sometimes I'm a little slow. Except for the traffic & dog stirring things up I should be good for a while. On to the system 2 swap.

Vulcan, who did you buy the tubes from?  I've settled on a pair of Mazda's in my Ultra DAC and a pair of RCA clear tops that I am buying from Martyo to use in my Ultra preamp.  But I am curious about different tubes and how they sound.  I've lost some transparency and sound stage with the Burr Brown OP Amp upgrade to the DAC so I'm looking for the right combo of tubes.  The EH's gave some of that back but they are way too bright and sibilant.  I just may have Frank put the old op amps back in at some point.

Hey DogRacingMan,

I bought these tubes from Karel de Grotelaan (Tom), @ Webtoco, Netherlands off eBay.

He says the Mazda can be a Philips tube also when it has a triangle starting in its etched code.

I like the Mazda also; I keep coming back to them. I agree with you on the EH tube sound when in my system also.

Last night after listening to the Tesla tubes E88CC, I didn’t like the bottom end sound. The Philips tubes ECC88/ 6DJ8 really have a nice midrange sound with sweet highs.

After I have a little more time listening to these, I would be happy to forward some for you to evaluate in your system.

I have a pair of NOS Siemens which have a plated middle plate which is suppose to be rare which I’m “fixin” to try.

Harrison,

Do you notice any change in dynamics with the "6" tubes that are not the 6CG7's. Thanks 8)

Martyo:

I am glad you brought that up. I do !  i was wondering if it was just the tube manufactor type; Philips, RCA, etc but now i do think it the so called longer lasting tubes.  I have noticed with the special higher output, longer lasting tubes, that the dynamics increase especially bass notes. At first i was attracted to the bold sounds but after listening to them more I dont think I care for it. It seem to mess-up the overall tone to much.

I was wondering if it was just in my head.

Do you like it?

One other thing. I do like them better when listening at relatively low vol.

Harrison,

I haven't tried any myself. I had heard that they were less dynamic and was just curious. There are a lot of other "6" type tubes out there, a generalization probably isn't going to work. And system synergy and all......

Thanks for the feedback. 8)
