Maybe this is a mic problem, or a Sunfire problem. But, like I said way back when, the raised floor sink is not only the 5 Hz structural/footfall resonance, but it is uneven broadband + & - with respect to hi-fi, and the helluvit is that your ho...

It does not sound right to me. If I am not mistaken then it has 2 X2uF caps. What 10uF coupling cap can do there and what 1000V cap does in ML2. The 1000V cap is almost $6 more expensive – Lamm would kill himself but would never allow such a waste of...

Sounds too good to be true, Romy. But it is winter, and I admit I'm still holding my breath.From the reports so far, it looks like the thing might be worked with to good overall advantage; but, as usual, some significant adaptation is...

Hello Romy and others,Ive been away for a long time taking care of my health but i'm back with renewed interest. I am moving to a new house in the future and have plans for a dedicated music room (and an occasional movie) The space is however much sm...

Collin,I do not know why you guys dive so fast into self-Moronism rebattling – it was absolutely not my thoughts. The escaping from family is one of the “permitted” reasons to built dedicated listening room. What you do: planning ahead is perfectly n...

With the electricity being so bad my listening has been limited, and what I've been hearing has shifted my focus somewhat, which is annoying, to be sure, but it is also educational. I have been playing around with plate loading a little and not...

Hi Romy,
of course, no manufacturer give one value only (non that I would know), but will spec. a range starting with some value e.g. >10ohm or say >100ohm and either putting a cap at 500ohm, 1k or nothing at all, meaning 47k (if that su...

Stuck,
You can NOT stack coils in series to get a “distributed half order crossover”. To make it “distributed” the first and the second first-order filters should be decupled. For instance the first filter might be at line-level and the second at th...

Alex, I think that there is VERY high probability that your hum is from transformer-correctors interfaces. Get rid the transformer, change the loading resistor accordingly and use the corrector with high outpour cartridge, let say over 3mV. If you w...

Today I spent many hours trying to remove large LF transformers from Melquiades belly and replace them with another one that would load my 6C33C a bit harder. I do idle my output tube very hard and my objective was to get to let it go slightly. The ...

I would have to say that loosing Gabo is a far bigger tragedy than damaging any sort of reputation I might have.About making horns I don’t yet see this obsession as a full time career, and if you ask I just as well would not be able to answer what dr...

Of course i am referring only to the horn part of a 210-type enclosure. Below the horn cutoff, perhaps around 70hz for the 210, the remainder is filled in with a wooly bass-reflex peak, which gives these boxes their characteristic fluffy, indistinct,...

It seems like you are saying that so loading the motor somehow makes it more accurate, so it sounds better. Is this the case? I thought the "most accurate" speed control was DD with a servo (that only "corrects" errors after the fact), as "measured...

Mark, here is the the point that I make. You said that no matter which direction I went off of the baseline you couldn't hear much of a difference. Then use other methods (microscope or not) you did found the direction and distance from that baselin...

Gentlemen:I've thought about this mid-bass challenge for quite some time. I have tried many approaches.For the sake of my example, let's assume mid-bass to cover from 60-600Hz. That just happens to be the classic "decade". I have to fully agree with ...

[quote user="cv"]Little suggestion should all else fail - you could have a rudimentary phase plug machined that would give you the same (or similar) compression ratio as the original but only one annular exit path. This might preserve the driver char...

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

Ok, I blamed the tweeters and MF drivers now the turn of the MF horns. The Mid Frequency Horns (I’ll them “MFH” from now and on) are the stinky like pieces of horn installations, and if they are not done correct then they screw up anything big time T...

Oh, yes this is the whole idea of Remedies, it is not only a Red combination but it is an assembly with midbass channel which would make it a conventional box loudspeaker. You see, with all interesting things about Tannoy Red the woofer part of t...

I do not have good-sounding high output cartridges; my most high-voltage cartridge is SPU MONO that is 3mV I believe. I have 5mV Grado $300 Platinum Ref that is high-voltage cartridge but is sounds not seriously. My desire to bring my 3mV SPU via my ...

Novygera,If you are really going to run a single-ended pentode as a pentode (not triode-strapping the screen grid) then you will almost certainly need to use some negative feedback, whether global or local. It is partly needed to reduce distortion, ...
