Hey, Ed,

Sorry for taking so long to reply, but laot going on, some ok, some not...

Anyway, a query to diyaudio's Pass Labs forums yielded the info that the power tip for the kit is 5.5 x 2.5. Found a pair on eBay for <$20 including shipping. Look like the ones that disappeared when we packed up the "entertainment" room for painting. Found the amps ok, but a gremlin musta wanted the PSUs. Nowhere to be found...

Next: I have a decided hum coming from my Truth's right channel. It seems to be in the volume control as I can get slight variations in the loudness of the hum jiggling the volume control knob. Otherwise, the hum is an annoyingly loud constant.

May I box it up and send it to Papa for ministering and healing?

MTIA

Harry

I need recommendations for a source to buy a pair of PSUs for Amp Camp Amps, please.

Brands, voltage/amperage, etc. recommendations are also needed and appreciated.

Not to worry, Ed. For many (some say too many) years I was the sole BA (history/lit) in a division of math, physics and geology PhDs. I survived and thrived because 1) I've an excellent BS detector and 2) If I were given an equation, I could code it. Not necessarily understand it, but code it.

I must admit, 'tho, to this day the Black Body Problem gives me bad dreams...
4  General Category / Technical discussion / Golden Ratio? on: January 08, 2015, 04:32:06 PM
Is there a Golden Ratio, or even a rule-of-thumb, as to distance between Horns and distance from Horns to listener? For various reasons (I'd say WAF, but she's looking on...) the Horns are not and will not be corner loaded. Sub is an SVS crossed over at ~60 Hz with volume about the same as the Horns. Room is asymmetric with nooks, crannies, bookcases, sliders to outside and other doors.

The SO & I are beginning to get semi-serious here. We even have a Truth on order.

Amp is First Watt F1.

MTIA, as always.

As youall know, Nelson Pass' First Watt F1 amp is designed for single driver, crossoverless speakers (The Horn). Does this mean I cannot use Ed's Heils + crossover?

Goal/hope is to improve upper registers, especially vocals. SO & I are opera/choral fans... Also higher register strings, flutes & brass can be somewhat piercing.

The Horns are NOT (and will not be. WAF principle has been invoked...) corner loaded. I use an SVC sub set at ~50hz.

System is First Watt F1, Eastern Electric Mini Preamp & Horns. Sources: Bolder modified Squeezebox & OPPO BDP 83 -> Musical Fidelity V90 DAC. We are generally really very pleased with the sound (and appearance...) of what we have.

Important data? We are both in our 70s and, thus far, do not need hearing aids. Knocking on wood sound...

Any and all suggestions, opinions and comments will be appreciated.

In advance,

Merci beau.

Many thanks, O Great Guru...

Next question: Will I get more "bang" for my kilobuck tax refund getting the Heils or the Truth? Most listening is to classical (CD/DVD, satellite, vinyl, Squeezebox) and acoustic Americana. listening room is your basic 3rd bedroom.

Two days is not a huge data sample, but WOW!!! Horns do have a low end.

A query: Should I leave my ACAs on when not in use? I used to leave my B&K ST140 on. Some thought this was good, some thought it didn't matter. I do get a bump in the horns when powering the ACAs down, with pre-amp off.

My SO sez (and is, as always, correct) that I left out what may be the most pertinent bit on information: The more complex the musical information the speakers get, the poorer the reproduction and sound. String trios, singer/guitar player, etc. all sound pretty good with good instrument placement, sound stage, tonal quality, etc. Large orchestral pieces, choruses, etc. sound terrible.

Our plan: After we do our annual garage clean up/clean out, I'll set up a rig (amp, CD player, speakers) in the garage, let it run non-stop and start with a week of rock'n'roll (Dick Dale sounds about right...) and then a week of Mahler's 8th symphony. I'd like to think that 300+ hours would serve as sufficient break in time...

Thanks to all who took the time to reply. You guys rock...
9  General Category / Technical discussion / Hornshoppe Horn placement in less than an ideal room... on: December 17, 2012, 01:44:01 PM
Back story: Our next door neighbor has "given" (ie, pay what we can...) my SO & me her late husband's Horn Shoppe Horn with Fe108 Sigma drivers. Our listening room doubles as the SO's sewing/project room, a basic 10x12x8 3rd bedroom. There is 1 (ONE) unoccupied corner. Bookshelves, storage units, sewing machine, etc. are everywhere against walls. Our current system is a Will Vincent DYNA ST-70 (tube, triode) driving updated (Bob Crites stuff) Heresys. Listening is classical, opera and acoustic Americana.The sound is surprisingly good and we are mostly pleased, especially given the circumstances and surroundings...

Problem: We can not find a placement for the Horns such that they sound as good as what the various reviews would have us believe. The highs are beaming and piercing, the mids and lows are mostly missing. We have tried ~18" away from boundaries, we have tried 8" away from back storage units and ~18" from side walls. We have tried just about every geometric permutation/combination we can think of. No bueno...

Questions: Are the Horns simply not appropriate for our room? Would replacing the driver's with the latest FE126EN drivers be worth our while/money?

Any ideas, opinions, suggestions will be appreciated...

Merci beau,
