    I see that there is an Irish company selling skirts for men , i think i will have to get one , this will help getting a Ecofan price reduction ,
    I have a few purchaces to make this year a battery powered el95 parallel single ended 5w for my car audio ,and his phono stage , i was telling him that there is a very highly rated phonostage called Allnic and this man like him winds all his own chokes and transformers so he has good respect for a man like that ,

    Default Review of Ecofan Sound preamp and power amp.

    Here is a bit of a rant from the "Design Side". Something to keep an eye on is "Headroom". With headroom comes low distortion. I think the new version of the Line Amp should have both volume and "gain" controls. There seems to be a bigger variation in output between digital discs, especially music videos, than other media. This means you con overload the first stage if the volume control is further along in the circuit, reducing noise and in this case not being a voltage divider. Using the "passive" preamp (valves for the phono, just a voltage divider for other input selections) i have found lately a huge variation in output between some music DVDs, and have to back off the voltage divider on for instance the Dixie Chicks, compared with Mary Black, where the voltage divider is full up and the recording of the band sounds absolutely beautiful! As good as the vinyl. I have a Garrard with Pritchard low mass rosewood arm and Garret Brothers cartridge. Sounds good to me but obviously not one of your $30,000 monsters. In fact get that album: "Mary Black Live". Two discs: Live at the Olympia and a doco: Still Believing, and you'll see what i mean. Only got a "Garrard" of a DVDplayer:"Yukai". Refuses to play some discs sometimes,then, for instance the Cowboy Junkies can be heard (seen) again after an absence. A friend gave me that machine when he upgraded. Much better than MY other one though!

    Default Review of Ecofansound power amp and preamp.

    I'd say that system should be transparent enough. I use the same Line-amp as in the review above, but driving the "lash-up" of the 12wrms SEOTL power amp. That has been running for a couple of years now, and doesn't seem to be going through 6080s. That amp has good, and adjustable damping factor (without feedback) and certainly "crisps" up my 12" cones. The tops and midrange are professional pressure units (British). I have gone to a lot of trouble getting a natural, believable female speaking voice. That is one of the most difficult for speakers. Male not so hard. But what i was going to say was that no matter what gear you have, we are at the mercy of the joker on the desk at the recording. For instance a really good album (on DVD) suddenly has bass half way along, as the bloke wakes up and discovers "Oh--uh....better move that up...zzz." It would be good if some sort of standard on the levels could be achieved. The engineer on the Mary Black album should be given a medal, and most of the other jokers the sack!

    Very true indeed JW. Mary Black's music is very good indeed. Mary's music was first discovered in the show room of a shop I used to work in. Dave Marchant of Mission, was visiting and in full flow (if know Dave, you will know what I mean)when he heard her on vinyl (I think...it was 20 odd years ago) he thought she was amazing, and took her under his wing a bit, and used Mission speakers to promote her and create the first Mission demo CD. She was a firm fave during Hi-fi demos for years, a bit like Eleanor Mcevoy is now.

    Default Mary Black

    It would appear that Mary still has a top engineer. I wanted her on vinyl (probably still do) but that DVD was there for the plucking at Real Groovy Records (yes they are still big vinyl nuts!) I do think on Digital Versatile Discs there is more audio room than a conventional CD. They do seem so to me. If the engineer can do his job. Of course if the cam and sound guys were really on the ball, when the piano was soloing, the guitar would be not still showing. Dunno if that is all that hard, but some groups do a lot better job of it than others.
