See if you can audition a Puritan from a dealer. It is a nice step up in dynamics from the Niagara 1200. That is one side and perhaps someone knows both sides of your question.

Great minds...

After months of listening to the stock pads, I put on the thick pads and am suffering from sleep deprivation because I cannot stop listening. I prefer the thick with my set up with the Envy and MU2.

I asked the audio dealer I have worked with recently about transformer hum. He replied with the following: "Transformer hum can be caused by a number of issues. Transformer laminate saturation from voltage or current levels that are above the TFR's idesign spec. It is like a car's engine...

Yes, the PSM 156 is a big step up from the Niagara 1200, which I now use with a TV, and where it improved the image quality substantially.

Not exactly a straightforward comparison but I tried removing my PSM156 from my chain and plugging the Envy, Grimm MU2, and Innuos PhoenixNet all into the Yeti Acoustics power conditioner. The sound quality clearly worsened. So I went back to the original configuration: MU2 into the Yeti and...

I just thanked Western Electric. One of my new WE300B tubes had a slight staticky ticking that stubbornly remained after at least 10 hours of burn in. The tube otherwise sounded the same as the matching one. An RMA was emailed from WE and one week after sending the tube back the company sent me...

I am not promoting any vendor but did get notice today that Tube Depot was having a NOS tube sale. Maybe someone here might find a goodie. I need to stay away from these sales and instead learn how to cook better. https://tubedepot.com/t/tubedepot-sale

This is like a tube supermarket in here.

WE website notes nine hour pretest. A NOTE ON FILAMENT BURN-IN The filament of a Western Electric 300B is aged or “burned-in” for nine hours following strict procedures established by Bell Laboratories engineers. While this initial duration is sufficient to meet quality control standards, a...

I wanted to mention, besides the quality of Elrog and the Western Electric tubes, the online response from these two companies is within hours and informative. How rare is that?

I finally opened up the cherry box with the WE300b pair I purchased in November, installed them, and turned on the Envy 15 minutes ago. Earlier, I noted that I am 4.5 months late sending in the warranty card. It is a long story, but I did not have a working audio chain for 3.5 months while...

Well, we are a very private group...

Has anyone noted the venting in this picture?

No wobble at all with my Envy knobs, either. I never heard about that before. I'll have my downsized headphone chain set up in March. I have been waiting almost 3 months without music. And I have three additional sets of tubes from recommendations from all of you to play with that have not...

I already confessed, with my head down, to my wife. She knows there is no end to this hobby. And things could be worse.

You folks are a naughty influence. I just ordered the Telefunkens and the CBS tubes and I do not even have a functional audio system until next month.

Very, very clear photo. Where did you buy these tubes? Someday, I may grab a pair.

I've done all but power supply change to Qutest. Many others here have gone through the steps as well and will chime in. As you concluded, probably best overall option is buying the used TT2 for big step up, with added utility and potent bass. And better interconnects with HMS are almost...

Great to hear this news.

I bought a Puritan 156 with the Ultimate cable and it made no difference with the external hum from my very early production Envy. I thought for sure it would resolve the transformer hum. Music, however, sounded much more dynamic with the Puritan filters than from my precious Niagara 1200...

You described the condition much better than I did. I don't think I developed it from the headphone listening but more from my age. I am hopeful that the introduction of Rob's Ultima upscaler will uplift this DAVE forum. And I am certain it will do the same for the DAVE. Finally, I feel...

I ordered a new Dr. Sean Jacobs ARC6 DC4 with Mundorf wiring and capacitor board last year. After at least three months of burn in, my Dave/Mscaler began to sound magnificent, a real "meaty" beast; Dave II had emerged. You just need to hear it once to know. Unfortunately, since then, an...
