friday we had a good test , we use Roon Labs software.tone was very similar in both CEC and Berkeley but i am not sure about our system tone resolution because we connected a push-pull amplifier to 2way living voice speaker.in our test Berkeley was g...

Hi Paul,I'm really not sure how else to explain it, but essentially it is "free air". The driver does not become influenced by a defined amount of "trapped air" in an enclosure, thus, it pretty much maintains it's free air specs. In my case, the driv...

Hi Romy,I am very interested in what you have found out about the 6C33C tube lifetime because I am using a pair of Silvaweld OTL tube reference (their name for them not mine) amps that use 4 x 6C33C-b tubes per monoblock (so a total of 8). Thes...

Paul,Rather than go SS, perhaps you should consider push-pull tube amps for each of your five 92-93 dB-efficient channels (I assume "channels" means frequency bands, not HT5.1 or similar.) Along with that, consider using a modest amount of global ne...

[quote user="hagtech"] I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. [/quote]
Good operation points for use it as a driver. You might...

You might want to try covering a section of plywood with the modified cement/mortar recipe as a test before you write it off as too difficult or too expensive. Basically, it does pretty much what you ask, and it need not be 2" thick, either; 1/2" or...

Thanks The CatI'm posting the pics of the build as I progress so people can see and pass on ideas, that's all. Are you suggesting you don't want horn projects shown on your site? I had earlier outlined the design, including cross-over points etc.I as...

As I learned today the Australian Martin seddon know as the Azurahorn Guy has a web site and he also does horns:
http://www.azurahorn.com/azurahorn_tradesecrets.htmlFrom Martin’s site:Azurahorn is best described as a long term audio project, funded ...

Is there a pill for that too? Seriously, it would be very interesting to hear what solution you come up with because I have converted from listening music solo to a small number of audience (friends). So much that I listen by myself much less oft...

Hi,[quote user="Romy the Cat"]T, thanks for educational reply. I understand what you are saying and where you are coming from but unit I try better transformer, presumably your S&B TX-102 I would not be able to correlate your observations with my...

...rather than something more culturally appropriate..."it's the bubbles of nothing that make it really something"Macondo + Melq, at least in my room unfinished and still mono, plays the silences between the notes so wonderfully. The notes themselve...

Gera, there is already a LOT of discussion on this topic salted around this site. I suppose you do know, but a couple of things you said made me wonder; anyway, at the risk of offending you (and not meaning to): "SET" means "single-ended triode" (as ...

I continue to be amazed at the varied views relating to BAD power at certain times of the day.I broke with that 10 or more years ago in moving to amplifiers, line amps and DACs configured with switched mode supplies.I not only keep my DAC permanently...

I don't know this Steve Klein. I don't know what bullshit he uses to sell Audio Note's products in the US. If that is what you are attempting to satirise then fine.I am quite familiar with Audio Note Japan's (Kondo) products. I don't use any at the m...

I think I have too much time on my hands or use my time in highly stupid fashion but I decided to do today the experiment about witch I was thinking for a while. The experiment was “methodology clean” and lead me to quite interesting discoveries. Sin...

It was not so long ago that the Super Milq was a twinkle in Romy's eye,and now it has come to the point he is a strong proponent of DSET (not to be confused with DH-SET). I am always a big believer in the power of topology. I was thinking about...

Looking at phase 3, one of the first things that pops out is the following:Skushino wrote:"...75-240Hz [from a] 12" x-driver [loaded into a] 70Hz [horn with an] 8" throat..."Because they are a royal PITA to make, you'll want to give yourself every ch...

[quote user="Romy the Cat"]Vasyachkin, to say honestly I do not think too much about dipole bass. What I head sounded unacceptable and it was unacceptable not by specific implementation but buy some common character that was characteristic to all dip...

Romy ThanksI had 6 pure power (230v version) since 2017 and now i have 4 pure power , the first pp3000 was faulty and it has the same problem that some users reported here (GSC) , the output frequency spectrum of first PP3000 had some extra harmonics...

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

user="xandcg"]I would like to know, if you do not mind to explain,
since you cannot drive your bass modules using SET, why you use Solid State
amplifiers instead Pentode or Push-Pull Triode?[/quote]
Well, I need to say that I

Somebody at AA asked about the difference between electromagnets and perm magnet. Thankfully the AA idiots who pick the pieces of brain at my site and already learned that the idiotic blabbering about “the electromagnets have more flux” is comple...

But here it is. I made this monoblock fit into less than a square foot. It is tight. I use Hammond iron throughout. Their stuff usually works pretty good for power supplies. I have some photos at my blog. [img]http...

[quote user="Romy the Cat"]So, Teflon, I do not think you got what I meant. SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demand...

Paul,It would be improper for me to write down what I have worked on over almost 40 years in the telcoms business. WRT a CV for example, I have in the past written it all down and the reviewers do not believe it. Eventually, i stopped bothering abo...
