I am not too worried about the 6C33C bass, since I have other alternative. Even if lower loading will improve it, the problem is to get more power out of the 6C33C to a 40W (PSE perhaps) level to be able to drive the 12in or 15in woofer, even then th...

RomyThis topic is relevant to me currently as I am attempting to get a 750Hz low-pass into a valve (tube) amp that is driving a bass section ( Supravox 285GMF in an Onken cab ).I have run through a few options in my head but can see various problems....

Ron, if I may, then as a software engineer, I would pass some criticisms regarding to what you do. It is fine that you are soliciting sponsors but I do not think that sponsors get anything for their sponsoring. The taglines that sponsors allow to...

As we have discussed, part of the problem is the co-dependency of "reviewers" and "manufacturers", so why expect sagacity from a "manufacturer"? In fact, even the traditional role of manufacturer is mutating into "specifier/marketer" ...

Thank you Romy,
<<The multiamping with Super Melquiades was made with intend to optimize the output transformers and to eliminate the interference between the inductance of the upper bass driver’s coil and the MF driver. I still use the speake...

[quote user="Chirag"] Well..my first question would be regarding the application. The big Melq tube is already doing the bass towers...is it not enough current? [/quote]
Chirag, I’m not planning to use this power amp in my system. ...

I have never liked power conditioners. They change the sound, but not necessarily for the better, much like playing around with the tint and contrast knobs on the TV.
So I was intrigued after hearing the glowing praise by Romy, who never gives out...

OK, I see.
Actually, I was planning on using the Druids with their ports sealed. Bad idea?FWIW, I have a pair of Wilson Benesch Chimera speakers (the UK-based manufacturer, not to be confused with the 'famous' US one) that I'm hoping to use fo...

[quote user="op.9"]I now run my 'tweeter' amp 1st order high pass at 2200hz (driving BMS 4540nd in 1500hz leCleach horn) so my impressions might have some bearing on Romy's new amps. I was playing around with operating points and components in my sin...

I'm working on a project that may be of interest to others, and thought posting to this old thread was a better way than beginning a new post.I use speaker level passive crossovers, between multi-amps (not DSET) and drivers. My desire is to move the...

The differences between the battery operation and AC operation are to be expected.One case is isolated (hopefully) from AC, the other case is not. If anybody thinks otherwise,they are fooling themselves.The first question to ask is to MAKE SURE that ...

[quote user="Paul S"] Fremer has just pitched these in the new Stereophile, and the online buzz is building . Isn't D'Agostino the Krell guy? If these are different than the Krell amps, then how and why ? Disclosure: I quickly dismissed the Krell...

[quote user="jamikl"] I recently saw a thread which may have been posted some time back to do with using a reflexbox for mid or upper base. My impression is that you are solidly opposed to using this setup within the rangein which it is normally us...

Perhaps there are ways to horn load Lowthers that do not screw up the sound, but I don't know of any, and there are other reasons, as well, for not asking LF from Lowthers.For me the best thing about the high-pass-limited Lowther DX4 in OB is th...

N-set, starting from reasonable input, the 6E5P can swing some serious voltage, and Romy also sings its praises in terms of sound. Maybe sim that, running it in its safe zone to a 6C33C. From there, you have all the power you'd want to drive -- what...

oi Romy ,Since you added a new parameter in audio play back called : Decor I'm afraid, it may make it far too hard.anyhow can I see 360 degree view of your room (video) ? I am afraid you are in wrong shape of set up in first placeFor instance from...

Haralanov, I've spun this thread off the "Speakers for a Powerful SET" thread, as you suggested. I took a couple of pictures, but I can't figure out how to upload them, just yet. I'm also not sure what you could see from the outside, anyway.As for th...

Mani, I am not saying that any driver (let alone any collection of drivers...) will ever be entirely "correct" in terms of acoustical instrumental timbre, no matter the frequency range it attempts to address. I am saying that the sonic "weight balan...

Hmmm... Now I have something else to play with. Next time I am set up to record I will make yet another pass at firebird with the Tascam set to 88.2 so I can see if I can hear any degradation in my downsamped 88.2 file. I wonder if some converters...

On the topic of string slippage: I don't think my string, the original one from MS by the way, slips at all once the platter is up to speed. It would slip on the motor pulley when first turned on, as the heavy platter must be gradually brought up to ...

Yep, you re right, the Yamamoto A-06S is SET, I did not read it carefully and I was under presumption that A-06S is PP monoblock. Good for Yamamoto! The only amps I heard with AD1 were PP. Somewhere in the very end 90s I shortly was exposed to i...

Paul -- I used 1st order & bandpass on the Beyma. I think that 2nd on the Lowther would have been better.I set out to try and extend one "way" from the end of a wide-range drive unit, downwards. This I found to be well nigh impossible -- perhaps ...

Guys, I think you are missing the point.
Regardless what technology the DG used the DG’ “Originals” series are in away different as they (allegedly) do use technology to guide sound with those re-masters but rather then use the trained ears of...

Okay, here's a graph that shows theoretically what will happen when the volume is doubled and a few other circumstances. It should give you an idea of what's going on. It is important to note that when the Vb is doubled, th...

Thanks for the advice Romy.But actually, I may not need new tweeters after all (for the time being, at least, until the dreaded 'Autumn Sound' arrives).You see, when I connected them up, I didn't really think too carefully about the speaker...
