Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

I got my pair of F120A by-the-book bookshelves a few weeks ago and yes, in the beginning they were very much "compressed" sounding. Things improved a bit over time, but the low treble (which gives instruments their "color") is still recessed. So I ...

Hi Dima,Do you know if this is similar to the approach Tim de Paravicini took in his direct-coupled amp placed inside a Quad? I'm currently using Quad speakers (I gave up on the horn approach through sheer frustration) and it seems to me that this is...

AlloThese weren't quads but ML CLS panels (well, just the one actually, leaning against a chair, clip leaded up ). How's that for even more unethical... To be honest, *I* didn't actually like the sound; found it a bit uninvolving, and muddl...

Romy, I thought the Ref3 mm-de capos sounded pretty good last I heard them. No idea if they are ported or not. I've been told the crossover is rather simple. To me, they did a good disappearing act. Probably expensive.For dece...

Martin Logan CLS are 85 dB efficient, so that is certainly more optimistic than ELS of old. New Quad 2912s are rated at 86 dB....

Paul, my headphones are electrostats that need a separate driver. I use Blue Hawaii amp with a quad EL34. The preamp has a direct output from the selector switch, which will be connected to the headphone amp....

[quote user="KOTriode"] Without regulation, this amp would not work correctly due to its design: DC coupled and fixed bias. The high transconductance will make the bias current varied as much as 50-100ma due power line fluctuation without the reg...

"So many people today are interested in audio only to make money, or for show, or as one of their many passing hobbies"I occasionally go to the meetings of a recorded music society. A group of maybe 50 mainly older (50+) people gather in one of the l...

Jarek, one might also consider that the "small" Auro-capable processors are 7.2 channels (larger might be 14.2). When thinking/speaking of "Auro 3D", I think we are a long way from Romy's original 2-rear-speakers "RI". It is still not clear to me if ...

Never used the old Hafler (quad) much, mostly because I had so many mono LPs at the time, and that system (if I remember correctly) worked best with hard-panned stereo. Basically, I agree with you, and whatever I wind up with will be fairly easy to u...

This would involve some researching... thus introduing (possibly unecessary) complexity: look for a Sony or Yamaha or Sansui "power j-fet" amp. These were produced s/where in the mid '70s and should be very cheap now. I have listened to a Yamaha...

Wouldn't you know it, Jordi has to work weekends, too, and it can only make it tougher for him that the rest of us seem to have nothing but free time, stupid ideas and bad attitudes.Meantime, while $100s burned in my waste basket, I ran across a...

my vitavox S2's finally arrived today.i was not expecting great results with all the warnings i read on this site,especially with the klangy stock 4 cell 330hz vitavox horn.i know refinement when i hear it.i have heard avantgarde's duo, trio,i even h...

Dear Roman and all... also unrequested/unsolicited, MUST give my opinion on the above... I had to translate my 2,3 meters from my Gotorama speakers system, and obtained 7,6 or so feet... it's angled 110° in front of my head, placed on 5,3 meters long...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

I do not know the “USSR made 2A9”. My feeling is that all USSR-made driver were crap but who knows, might be three is something did exist in there. It is hard to presume that if the guy changed from dual GOTO SG146LD to basically direct radiators wit...

There has been a low-ish buzz in the hi-fi rags for a while now, to the effect that perhaps we should reconsider "neutrality" and return to the musical-instrument-type speakers of yore. Of course any sea change is good for the Hi-Fi Industry, just a...

Chris,I wonder what your like in the Quads, the actual performance of the loudspeaker or the way in which those delay lines shape the front of the attack wave? Anyhow I thin to mention the Quad in the Vitavox S2 thread would not be ethical… :-)...

Hi Romy,
I spoke to Mr. GOTO about your question today and he told me that the reasonance of SG145LD4 is at 24Hz. If customer want to build a 20Hz, he will recommend to use at least 2 driver per channel but best to use 4 driver per c...

I found the frequently-power-starved Sound Lab A1s and A3s to be audibly more amp-connected than some other speakers, including some that do not get as loud in absolute terms. Although horns -generally speaking - may "need" SET to get...

[quote user="manisandher"]The only issue that I have with it is that I can't use the PMII in Master mode at rates of 176.4 and 192KHz... the AFI1 cannot double the clock frequency from the PMII.[/quote]The latest firmware 'fixes' this issue. The AFI1...

I think conceptually it would be great if everything were streamed even at CD levels. For 90% or more of listeners that would be an improvement. Given the wide scale manipulations in the remasterings being done by the iphone listening staff at the re...

This is left channel. Right channel is mirror image.I am using 6db active crossovers all around.The subs are pair of 18" Aurasound 1808 per side. The current midbass is the white color horn you see. It is Funktion One DS15. The issue with this one i...
