In casual listening while the Lorenz are burning in, they sound very good to me. After I get some more hours on them, I will A/B them with the Siemens to see how they compare. And I hope that others, with more discerning ears than mine, will also pick up a pair of these, so we can all better understand whether the Lorenz and Siemens are equal, but just slightly different. Or if one is actually better, that is more resolving, than the other.

Sure you do.  I feel like an outsider too but I still say what I want to say.  You should feel free to do the same, that's why we come here.

I come for the pizza but there hasn't been enough of that lately.

To compensate Clayton and I have been eating burgers and drinking 16oz pomegranate mimosas...but only on the weekends!

Will continue to follow the thread with interest, but not post.  Will continue to communicate about my amp directly with Glenn via PM.  It will be the best amp I have ever owned and the centrepiece of my audio gear.

 

Sorry.


Sure you belong here this is one of the most open and friendly threads on head fi .

Hell it might be more about food then audio

It seems that is most important of all things hearing nothing. 

Running tube heaters on DC.   

 

Sorry, Glenn.  I didn't realize I would start something with my comment.  I know how you feel about people expecting tube gear to be 100% silent all the time.  To clarify my own position it's not presence of the background hum itself that I consider bad, the slight hum in my OTL doesn't bother me when no music is playing.  But that hum negatively impacts the amps ability resolve very fine/small details in the music, sort of how you can't see fine details on your TV when there is static so I believe it's a noble cause to try and get that noise floor down as much as possible. 

 

But I'm obsessed with transparency, some people aren't as analytical as I am about this.  It also erodes the value proposition of the amp by raising the price a lot in order to achieve a small gain in return.  I feel I should really stress this point to everybody who is having an amp built right now.  So hopefully with this post I'm balancing both sides of the situation a little bit better in terms of perspective.


If the price of the basic amp goes from $650 to $1000 so be it for a improvement to solve complaints.

I really make very little money doing this I just enjoy making amps. But if I start getting complaints about little

things it takes the enjoyment out of it and there is no point in doing it.

So it is worth it to me to do this use the better transformer and run the heaters on DC.

This might make some of the options to be eliminated due to space. To do DC filaments it will take large capacitors

and a large choke taking up space. To use a larger chassis made by Landfall will add another $150 so I

don't want to do that.

The next amp will have a Lundahl transformer in place of the Heybore I will try with AC heaters at first if there is still a slight hum

I will go to DC.

Hi Glenn,

Clayton and I have done extensive testing.

We determined that the only hum we hear after the first mimosa (or tequila) is coming from Clayton. He does that when he likes the sound!

You should build the amps that make you happy...whatever that is.

I have never had an issue with noise or hum in any of my Glenn amps.  And, frankly, if I wanted a completed black background I would just use a solid state amp.  Tube amps are never 100% quiet but that adds to their charm.  My Glenn 300B amp is the best headphone amp I have ever heard.

I wish to state that I am very, very happy with my new Glenn C3g/SN7 OTL. My only disappointment is that I do not have any 5998s that are quiet enough to take advantage of the enhanced 5998 setting. That said, my 5998s sound very good in the 6AS7 mode. And I suspect that they wouldn't sound any better in comparable amps as they all run 5998s in the 6AS7 mode as well. Further, it's not like the 5998 is the only tube worth running. There are a number of other very good 6AS7/6080 tubes out there. Currently, I am running a Mullard GZ32, GEC 6080 and Lorenz and Siemens C3gs, and grinning ear-to-ear. :)

 

I don't think I could be happier.... And I think I am very, very lucky to have it.

You are Ken.  And I look forward to hearing it, and put it up against the Vali and Mjolnir.

Now that winter is finally breaking, I hope we can set up a mini-meet soon. :)

Any time, my friend.  Literally.

post #11204 of 14436

I would never expect a tube amp to have a completely black background, if I wanted that I would go the SS route.....but I do not want SS....I like the tube sound too much.

 

I only read the talk of the Lundahl transformer here on this thread  and asked Glenn if my amp would take that option, he told me it could if I wanted it...so I said, what the heck....less transformer hum sure sounds like a good thing to me, even at the expense of not having a rectifier tube to roll.

 

There are still plenty of other tubes to roll in this amp :smile:

 

If it is not an option, I am fine with that also....just want a great sounding amp with my HD800 and one that I can have a little fun rolling tubes with  and I am sure what ever Glenn makes will be outstanding

 

I have wanted one of Glenn's OTL amps for about a year now, ever since I first laid my eyes on his amazing work, and heard others talk about how great that they sound

 

I will feel very honored and proud to have one of Glenn's  amps to listen to, and I am very excited, knowing that i will get to listen to one in the not so distant future.
