Part of setting up a system is listening to both channels independently, they measure the same and sound the same, but individually with a lower volume and punch, and of course no stereo effect." the audio window should get larger and larger, unti...

[quote user="Cosmos"]Indeed it took me a very long time to decide upon regulate or not. I ended up with regulation option to save some chassis space and weight, otherwise I would need at least 10 kilos more and 30% bigger space that would make the wh...

Glad to hear your bigger family is doing well and that you are making good progress on the room.Why not try a quick test. Try connecting your laptop to the big system, put the laptop a few feet in front of you and watch a movie or a concert? That wil...

Jarek, how many 10" Scanspeaks do you think it would take to get way down in your room? And remember that, according to Romy, the "best sounding" Dannoy, the heart of this speaker system, still only plays up to 90 db peaks (70 dB continuous with seri...

Similar experience but I get to keep my "old" room. I have just changed my 5 way horn loaded down to 140 hz speakers to a friends room twice as big as mine, with an open back area into the house as your new room has and one side and the front have hu...

Romy, for one thing, you are still talking "best possible sound" in a very literal way while most other people are merely working out one or another acknowledged compromise, or they are hoping to make their system do an even more spectacular renditio...

Hmmm. I need to admit that I did not read the article above and I did not familiar myself with the author’s reasons as I stubbornly consider Fremer to be an idiot. However, purely hypothetically thinking on the subject I wonder why the presence of mi...

[quote user="haralanov"]N-set, a friend of mine built an amp with this monstrous USSR tube. It has 3 stages and the GU81M is driven by 6C33C. Within context of driving mid or high sensitivity bass drivers, this is all you need. In comparison, his pre...

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...

As to the best transformers souding more transparent than the best resistors, I'll believe it when I (don't?) hear it. You claim to have heard this but I most certainly haven't. Based on theoretical arguments the noninductive metal film r...

Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

Howdy all,I have been playing with the Dunnoy concept since Romy discovered it and I agree that it is a very good improvement for Tannoy bass.Dunnoy with reverb injection is a phenomenal experience. I have gold drivers not red but I tried both 10s an...

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...

[quote user="Paul S"]20W from a 300B? What? I missed that. [/quote]Actually then call themselves Moonoblocks, it means that they use 2x300B for channel, probably paralleled or in SET PP configuration like Audio Mirrors does it. Still it is pushy fo...

Romy, I have been trying to explain to myself what happened and how I got to it and trying to recreate this wonderful boiling point.
I tried to make a write up of all the steps needed in order to make it happen, but it is ever so elusive. I ...

I'm precisely fighting with dialing-in the RIAA....I tried to follow (parts of) Romy's description earlier in the thread, but the anti-RIAA method and test LP give me a huge difference, much bigger than 0.2dB (rather 10dB or so):what was +/- flat usi...

[quote user="Antonio J."] … looking like the Kemp's unit. But that's provided the input electricity is still under 5% of distortion. They also state that that performance is under linear load, so it might be possible that using chokes or trannies loa...

There are no personal preferences that might be pleased by any complimentary adjustable properties. What I mean: if listeners have civilized and serious ref...

Rowuk, first of all, I very much recommend you do not undertake the Paul’s advice and do not go for any implementation of bass with bigger drivers or more driver of different topology of bass section like OB and so on. For sure better bass would ...

Nice thank you for the link, see the "lo SE100-1", 169.0 USD for 7Kg, it's cheap and they look good.So I was Happy with my choice of parallel 845 (I was hesitating with GM-70 but after a difficult decision I decided that the GM-70 filament consume tw...

I'm curious about how you set up your horns in the room.From photos it looks as if they are fairly close together, compared to the wide setting you suggested I try, while our room dimensions are fairly similar?When I started pushing the horns apart a...

Romy, it sounds like, as usual, you have covered a lot of ground already before you put out your first questions about ribbons.FWIW, I presently use Arum Cantus G2Si ribbons, phasing them in at 10k Hz to supplement the Lowther DX4's dreaded...
