Stefano,
I do not have any strong objection regarding to what ALE do. Bent bass horn are more evil then straight horn but considering the small throat of the ALE drivers and their desire to make it to work low the length of the horn become to...

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...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

[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...

As usual, great advice Romy. Cables…. It is all depends of the cable and current.At it's highest 2.5V setting, the FryKleaner Pro passes ~25mA current. I don't know if it scales proportionally for the lower 0.78V & 0.25V settings at ~8mA or ~0.25...

[quote user="Romy the Cat"]Hm you are true in the “terra incognita” territory as far as I concern. The preamps are mystery to me. All my attempts to make any decently sounding preamp or even buffer failed. To me Placette was truly God sent and if I g...

[quote user="Romy the Cat"]Let pretend that we have a hypothetical playback that plugged to the wall and power but known bad electricity. The decisions that were mane within this playback reflect the critical choices that were made for the given play...

[quote user="drdna"] I can tell you already it will work. I have experimented extensively with adding lengths of metal to cables. It works well, but you can do a lot more by fine-tuning the amount of metal and in fact adjusting it slightly from l...

No "cost assumption" was made or posited about bearings, rather the remark was framed as a question, just wondering, likewise the very general remarks about belts (along with the closing disclaimer). If the air system is cheap, effective and reliabl...

Among all my mocking and humiliating the people who do audio professionally (well very few of them do it professionally, mostly they do it “for leaving”) I have to admit that there is one subject that made me to envy to some of the guys who do audio ...

Paul I slightly surprised about your comments. The regulating aerial amplifier tube affected sound very mildly, if ever, at least it was my experience. I had a few different 6AK5 but changing them was not a highly notable effect. I still have left a ...

After I spend so much time in experiments with ports, I found some interestind aspects in port loading. Our primary objective is to eliminate the nasty air resonances in port at middle frequencies, which kill all the lower midrange sound. It is achie...

Lots of good, relevant information lately in the new "Basic Guide to Advanced Audio" thread! But I don't want to orphan this thread because it is specific to speakers, which at this point means, drivers.So, germane to drivers, where should one start...

playing the records for the last week I kind of turned to like it…
again. The renaissance of record playing habits? That is interesting….

[quote user="Jorge"]I guess it would be simple enough to add a couple of inches in order to bring the throat down to 4" in order to try the Studio 8M. I have already reduced it temporarily to 3" in order to try the JBL 2490h compression driver. ...

Any computer does absolute the same level of universality by being a digital file player. My telephone does it but I do not call my telephone a “digital transport”. Ripping CD it is not what your devise does but the fr...

Well to pile up superfluous things into audio components in order to make products more expensive is not alien thing in audio. My question was not about to mock the Raven company. It might be fine TT, I do not know anything about them and I do not p...

[quote user="Dresden"]I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.
As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to ...

[QUOTE]So what is high end audio, then? I know for some it is the quest for
the perfect soundstage, but let us exclude them for the moment. Rather,
is it a way for us to become more connected to the Sound? In a sense,
like a crutch for an invalid ...

I started in hi-fi with LPs and I have never stopped using them as my principal source for hi-fi. Some time ago I decided that master tape was better than vinyl, but I could not afford to go that route; so I settled on the next best thing: a cartrid...

Well, I finally found and implemented a digital front end that I can live with. I have been so cynical about digital up to now that I have kept and used an old, cheap Sony player (albeit one actually made in Japan...) because up to now it seeme...

After much research I found the radio that I like. The decision was base mostly on the esthetic: size, color etc, sure I was conserving the circuit but only up to point. The choose when for German Schaub & Lorenz Goldsuper W42. It is 1957 ra...

[quote user="jessie.dazzle"]However, I must say, I have a lot of trouble accepting the idea of redundant drivers. [/quote]

I am in minor scale mode toady and play mostly chamber music and only records. FM broadcasts with all their majesty are hardly objective tool to assess what doing on with audio. So, I play records and tapes. Besides everything I am trying to figu...

Well, Gera, a good question in context of your playback. How a person who has multichannel 106db playback with SS amplification and active crossover to explore SET domain? It is not so simple and if you do then probably it would require bringing ...

I am with skepticism treat that information about those WE demos. WE never did any interesting playback system solutions that might be stimulating in today home audio environment. At the time when WE was operational the requirements were very differe...

[quote user="Paul S"]It is confusing, but the NEUTRAL is not only "referenced to ground", but in properly-designed components it is THE ground. If the PP2000 is a 120V device with a 3-prong plug, then it has 2 references to ground within its chassis,...
