Shigaraki and other simplistic gear

Ed:

Is that (the impedance) a problem for the 47 Labs chip amp?

Changing it does alter the sound (my Bottlehead amps have 4 and 8 ohm transformer taps, plus some of my vintage amps have 4, 8 and 16 ohm taps), but if you are already in the synergistic ballpark then adjusting the impedance one way or the other offers no benefit.

Is this what the auto formers do, or is their more to them?

Ask Yoshi, @ 47 Labs USA/Sakura, about your amps characteristics VS the speaker load. Chances are that he may have an opinion based on using various speakers with the amplifier.

Which Fostex drivers will you be using (208S), also what type of enclosure?

I am going to drop in a pair of Fostex FE208 sigmas. I want to use what I already have, not having to plunge into another pair of drivers like the Jordan drivers. I think the Fostex will have better highs than the Jordans. The cabinets are those Garudas from ZHorn, a cross between many different designs....a back loaded horn with front output. I am running out of space, do not want to get more gear...cannot sleep on top of speaker cabinets and boxes, therefore of my choice of getting these cabinets and even getting the Shigaraki. If I am absolutely satisfied, I might be unloading gear via Audiogon. Strange how I used to be able to carry 60+ lbs amps without a problem, but now, I am either getting weak, old or do not feel the effort of moving and setting gear up is worth the effort.

Bemopti, I know exactly how you feel. I moved many times in the last ten years without any help. And, this was including the times when I had home theater gear including 60lbs amps, 80lbs+ speakers and a 120lbs TV. During my last move, even with smaller audio gear, I deferred my muscles to a moving company. I just can't carry anything heavy anymore.

Anyways, I think the Garudas is a good choice. Incase you don't know, visit http://www.thehornshoppe.com/. I think it is something similar and has a lot of good reviews.

Dave, I don't think I have any impedance problems. The Jordans and Gaincard are matched together by 47Labs after all. Even the 6moons' review of the Essence speaker is driven by the Shigaraki which has a much smaller PSU and 5 less wpc. But, I read a lot of posts stating the Gaincard and Shigaraki likes 8ohms or higher speakers. So, I am just wondering whether the autoformers will be a good tweak in my system. I am very weary about whether the autoformer will change the sound of my system though (adding impurities to the signal).

Regarding the autoformer, I think all it does it reduce the speakers resistance to make it easier to drive by the amp. I am not sure if there is anything more to them, or if I am correct at all.

Viggen, I do like these acronym, sounds like a Saab model. I do not trust those autotransformer anything in my path. I have read much of the work that goes into them, and people seem to like them, but if you see the reviews, the praised that come from using them, most of them come from owners of Atmasphere OTL or some other OTL design amps running what it seems to me more of a heavy loaded speakers. The drivers you have are nowhere near as difficult or outrageous as those that I have seen partnered in those reviews. I recall many of them being some sort of electrostats and some even using the Merlin VSM. There is no way I can see how the autotransformer will benefit CONSIDERABLY the set up you already own. I am striving for simplicity, closeness to the source and putting a autotransformer, I do not know if THAT is going to be too good. I know the designer of the AUTOTRANS said that the signal does not go looping around the winding cords, but WHY add more distance, one more something while you try to be immediate in the sound, with the mm between signal and amplification as with the CARD? I vote to dump the idea of adding the AUTOTRANSF.....it will change the sound, but I doubt it will be an improvement that might justify the cost of the time to get it and set it up.

PS: Cannot afford to pay moving people for the gear I have, cannot trust them with such sensitive equipment, so being a Do myself type, I am trying to DIET my extra audio pounds.
