I do not think that it is a mater of the output tube. Yes, the 300B is crappy tube but it is too easy to blame the under-performing tube. I would say that in the situation that Scott is experiencing the problem is not with his amplifier but in the id...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

[quote user="Romy the Cat"]Hm, interesting. The problem might be in ADC, I/O cared, Recorder or DAC. When you do the experiment do you record the file? If so then you might plug ADC directly into DAC. Might your problem be with cloaking? I do know wh...

Hi,I keep for many years a set of speakers, JBL 2225h, JBL 2105h and JBL 2403h and I'd like to build a reflex compact speaker with a good low response (see the picture 1:10).

[quote user="skushino"]So next week I will broaden my playback experience by adding my new 90wpc PP mastadon, and Romy's approved Lamm ML-2, in addition to my current DRD-300B amps. And as a personal favor to the readers at ...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

Romy,
Thanks for the hints.
I was anticipating the limitations imposed by of a pair of SET amps such as the ML2s driving such a system (4 or 5 drivers per side, down to 40Hz), but was planning to accept those limitations for the moment... takin...
|
|
I also find SET bass to be the overall best I have heard - at its best, and this has been, as you observe, when the amp is well within its comfort zone. And this seems to remain true even when Z out and speaker load "matching" are har...

It seems like most audio "auditioning" is of the hopeful sort, where we can in the best cases "hear something" that attracts us, and we can perhaps use experience to try to "intuit" whether we might be able to "extract" and use the particular compone...
|
|
Ok, how to start. First of all we have to understand that out subject of attention will be a region between approximately 80Hz and 500Hz or something that shape the fundamentals of the “melody range” within your playback. Search my site I have writte...

There is really nothing of value to add here. I just want to put this back at the top again.Paul S ...

I can see objections to using paralleled tubes to achieve higher power where the channel has a single driver, but surely where you have multiple drivers differences between the drivers themselves would render any disadvantage of using (say) one tube ...
|
|
Maybe no other hi-fi group has thought more about the cabinet's contribution to sound than the single-driver crowd. Many of them like the "immediacy", "integrity" and "purity" of the single driver sound so much that they endlessly hu...

This is not a safe "project" for the average DIY guy, period. Of course, the copycats are the last to realize this. Dreamers, if you have to ask what a veristat is, do not even consider this.N-set, not everyone has your education and background...

I did not make my mind about it but I have some “concerns”. Using SS amps and hearing different SS amps I do not like their bass and the notion of a powerful enough DSET to be able to drive ULF in A1 was born. Sounds logical. However, recently I ...
|
|
For whatever stupid reasons the DSETs (Dedicated Single Ended Amplifier) are not as popular among audio people as they SHOULD be and this imperfection I am trying to attack.
So, if you use SET for whoever propose then it fine but if you e...

I have not read this book (the wood effect) and if you have shopping link please sent it to me.I am not sure but It seems even amplifier speaker connection is important for sound.In past I have inverted the signal phase in my DAC and also inverted sp...

[quote user="Romy the Cat"] I do not really believe in the ultimate ability of SET amplifiers to drive loudspeakers, at least any loudspeakers. [/quote]Well - I've heard a couple of such amplifiers, made by Mr.Juri Makarov. They did have more o...

Here is an interesting article by Dmitry Nizhegorodov about his experiences to use 6C33C. (I do not know who Dmitry is) I disagree with Dmitry’s amplifier. Also, I very much disagree with his vision that an amplifier is juts a machinery where voltage...

Well, as I understand there is no truly GM70 vs. 6C33C context yet (sound in the respectfully equitable load) from you and it will be very interesting to hear from you when you feel that you are ready to say something. As I understand they are the sa...
|

Romy, of course I do not know if what you are describing is anything like what I hear from SETs, but that was my first thought when I read the post, the way it is so soothing - up to a point.I do not understand the relationship between the tube, the ...
|
|
Dear Romy, thank you so very much for mentioning our amplifier to your excellent forum. Indeed, during the last 5-6 years there are a lot of manufacturers “from non traditional hi-fi manufacturing countries”. In particular, in poor old Greece we ...
|

Nope, I am not familiar with sound or applications of this tube. It is indirect heated beam tetrode – why would it be any different from the whole family of beam tetrodes? From my perspective it might be interesting for ULF DSET solution as it has a...

anyone familiar with the sound of this amplifier RH-307a?http://rh-amps.blogspot.com/2013/09/rh-307a-v2-super.htm...

Well, have a good time, Stitch. Generally as far as I know Lamm equipment not modified a lot. When I own Lamms I make some minor changes that were not modifications but rather accommodations to the needs of my particular playback.
I would say that ...

[quote user="Paul S"]I think it is fair to say that no big speakers are going to "work" up to their potential without some serious effort expended in setting them up. IMO, this is no small matter, and Wilson obviously agrees,&nbs...

Rony,
After reading my post about the undersized core (for the given current) of Lundahl transformers you might be an impression that Lundahl are some kind of second choice. The undersized amorphous Lundahls forum is second chose for an ultimate ful...

Reading the Yamamoto link you posted, it actually says the amp is an SET stereo amp, not PP. You may have been confused by the schematic shown in the EML link, that showed a single channel of an IT-coupled PP.
I certainly have not heard any AD-1 ...
