As someone who had used a tube DAC in the past, I can certainly sympathize with enjoying a "warm" sound. It was actually a CJ D/A-2b. We're talking about a 30 year old DAC, tube based, and designed for 16b/44khz (CD) input. Now, the sound was "warm," "golden,", "relaxing," and "smooth." No ...

I Love the idea of the power indicator. TY for sharing

I own a pair of Premiere 12's (stock). Every once in a while I see a 120SE which has teflon caps in it. Which amp is considered higher in the line as a better performer. I may pick them up just to have them..I dont plan on getting rid of my P12's. Thanks

Ive never had good luck with EH tubes. I tried them in my P12 and they blew fuses like an MFer lol.

I just wanted to close the loop and let you know that the Mullard in the ET5 is astounding. I have about 72 hours on it and it is truly the best tube I have used in it so far. It is new so it should last long, it is nice and quiet not micro-phonic at all.

Has anyone compared them? Your Thoughts?

So I have about 25 hours on the tube and I have to say it is a very nice tube. very strong articulate bass. Mids are excellent with tonal saturation. highs are clean not spitty and not overly bright. An excellent tube.

In the past Ive asked Jeff if I can safely use KT120's in my P12. three times he said no. Recently I asked again this time he said "sure no problem" lol! Now I definitely wont use them lol

Just out of curiosity is the Mullard 6922 that you're using from original production or the New Sensor reissue?

I never did get around to trying the New Sensor reissue but did try the Mullard CV2493 which I used as the input tube on a Premier 140 and the Mullard PCC88/7DJ8 in a Premier 16LS2. I ...

Yes more time is needed. Ive read that tubes need 20-40 hrs as well as my ears.

So the Mullard 6922 (finally) arrived. Compared to the Tesla, it is not as lively. The bass is better on the Mullard and the Mullard is also quieter. The Mullard however almost seems muted compared to the Tesla (as I mentioned it was lively) The thing I have to listen for is does the Mullard sound ...

Nope it fell into the UPS black hole. Never to be seen from again.

OK so the retailer got the tube back and confirmed it WAS BAD. In the meantime UPS of course lost the replacement tube in shipping, ffffffaaaaaacccckkkk

WHEW! But do they sound good lol

yea I usually test tube pulls from suppliers, but for new tubes from reputable sources I dont test. I will from now on. In a previous post I said I purchased a Siemens 6922, that is wrong I purchased a new Mullard 6922.

Thanks. I ordered a NOS Siemens 6922. I also have read a lot about 7308 but they are mighty expensive

Has anyone successfully used a 7dj8 in their ET5? I bought one and installed it and got a boatload of loud noise. I immediately shut down the unit no damage. I reinstalled my 6922 and it is fine. I spoke to Jeff and he said that it "may" work but advised against it. Just wanted to know your ...

Has anyone tried Tesla 6dj8 in their preamps? Ive had good luck with the SQ. The only thing is when I activate the volume control via remote, the relays cause a slight ring in the tube. But the SQ is so good i will tolerate it. Kindly share your experience. Thanks.

Hi what output tubes can you use in the LP140m?

I think they could be improved with the full Teflon cap upgrade. RJ probably can give you extensive advice on the LP140Ms.


I thought the LP140M already had the better parts?!! What is the difference between an LP140M and Premiere 12 then?


I guess the thread is too long to actually read ...
