Yes, it is built according to the schematic, but by someone else, from whom I have only just received it. The opt is custom-made nanocrystalline amorphous core, gapped at 300mA and running 200V/240mA.It is quiet, precise and very fast (which last the...

[quote user="Amir"]Ear dac4 is not so transparent and it's volume control should be removed in my idea.[/quote]Amir,Good idea. I bet it will make a remarkable difference. Try to look for your ideal sound among true Multibit R2R DACs. For your informa...

The station that I most listen to is 105.9 MHz that broadcasts from one location 50 miles away at 100kW power and that is detected by 2 FM aerials mounted as a parallel array with rotator and ~ 40 feet of coaxial cable to the TU-X1. T...

J. Here is a start, If you want live hosts and quality FM broadcast with a wide varity of program material try CBC Radio, available just about everywhere here in Canada including the North West Territorys.Most nations radio stations have large budget...

We cannot view theoretical advantages of individual parts as the path to a better solution. The EAR phono corrector worked so well because the total concept was holistic. Thorstens modifications did not use the "premiere" parts to get the total solut...

Hi Keith,Interesting experience you have as I have found running my 505TT with the 160hz le'clech horns between 320hz-1200hz (with first order slope) works best for my setup and using my 15" goto sg-38wn woofer to play under 320hz (which sounds very ...

RomyIt's topical to ask, since I'm building a 4-way system at the moment ..( Tapped horn behind and three-way horn system in front )Do you favour the tweeter horn to be placed at the top, above the mid/HF horn , or in this situation place the tweeter...

[quote user="guy sergeant"]Isn't 330 ohms a little low as a plate load for an ECC83/12AX7 to be running into? 330K ohms perhaps?You often ask what is wrong with a given speaker installation, I thought you might be doing the same here. Keeping us on...

Hello Romy,Just thought I'd post my latest re-visit to this cartridge.I've played with this overthe last 2 years on and off between Helikon/VDH MC10. It was ok but did not make a big deal,so I carried on with the Lyra which was finebut not what ...

A friend has a fixed headshell model S2 and is about to trade for a detachable just for convenience but worries if there is any extra sonic merit in the model he already has?Any idea Mr B____p.s. Romy, I've got my 901 and I'm very much impr...

hI bRIAN, [quote user="Brian Clark"]The 834P was a revelation for me, being a circuit that I would have dismissed as "old hat" (Feedback? 12AX7 cathode follower? Do me a favour!).[/quote] Me too, but you know me, i'm mainly pragmatic. The EAR 834P is...

I do not think my topology is relevant, (it took me 3 months to get my studio horns to sound right 20 years ago so I expect this again, it is a mix of mjlouspeaker transmission lines and this midrange m4 trial. And it is actually 2 systems I am w...

Hi Romy,I feel very pleased for you. I was always somewhat puzzled by your descriptions of how you felt the S2 sounded, particularly between 600 and 1200 Hz. My experiences with a few different horns but always with a good quality SE amp were invaria...

Hello Chris, Yes, the 340s are superb. Martin suggested I cut them myself, but they're very nicely made and I really don't want to make a pig's ear of it. I wish I'd had him make them with an "adapter" so I could use larger format drivers. I didn't h...

Welcome to the state of the lost virginity. In fact the expresses of the 98 percent of people worldwide are irrelevant as if you know how time-misaligned sound horns then you would automatically discard whatever ...

All records, particularly from good period, were recorded at different equalization. Even the records that were RIAA marked were in fact WAY off…How to deal with it? Running a feedback to high impedance, in the way how it made in EAR 384P, permited u...

Chirag, I have some other guys who were asking about the 834P schematic. I just got home and made a picture of my manual with the schematic in it. I do not know if it’s legal. It sort of none-commercial site and I did paid long time ago for my first...

Hi Roman,[quote user="Romy the Cat"] the S&B unfortunately does just gain, nothing else) but for the money S&B do OK. [/quote]Then it does exactly what is asked of it, I asked JB to design it for me PERSONALLY as a "wire with gain". I have be...

In Macondo/Melquiades thinking, random process means random result - and that is exactly what happened with Dunnoy. A random driver was placed in a random cabinet with a random passive radiator and random cabinet damping. All subsequent attempts to r...

Well, they got John Curl's name on it, and it's "machined from a billit", 2-chasses, yadda, yadda. It also features the "new wave" balanced/presumed- differential topology and a "mystery"/proprietary (presumed discrete) first stage. Likely, it will...

Hello Stringreen,
First, though I do use it, I think the term "time alignment" is a misnomer... We should really be calling it something else.
When you say "Time Allignment has nothing to do with the placement of instruments in an orchestra", y...

As the builder behind these horns, I can answer some of your questions. It's true, I was primarily focused on the woodworking/building side, and now I'm experimenting with amplification and crossovers. I can't speak authoritatively on those subjects...

Decoud, this is certainly the evolutionary idea, all right, that I have been turning over in my head for a while now. However, even to start with, if nothing else, there is with FC the opportunity to "dial in" flux by ear.I cannot remember when, but...
