Default Pro Amp suggestions for subs and ribbons

Hi,

I wanted to borrow some of your knowledge/experience. I'm looking at
some proamp options for a multiamped hometheater system. One of the
amps I will require is for a set of 72" ribbons that measure cleanly
at 6 ohms; i.e. no dips, basically a resistive load. Accordingly in
this area I'm looking for an amp that is very clean in frequency
response and stable down to 4 ohms. One amp I'm looking at (because
it can be had cheap) is a Samson F1200. It can be found really cheap
in the used market, it is rated to down to 4 ohms and will produce
400/ch at 8 ohms (about the power range I'm looking for). Now, even
though I'm looking for cheap, this should not be construed as my not
being willing to pay what is required for a good amp. I just do not
feel the need to pay _more_ than more needs require in this area. Now
the ribbon is crossed over to a line array of Seas drivers at 225 Hz,
so needless to state the amp will be dealing with most of the midrange
and all of the treble. I will not sacrifice these areas for the sake
of saving money, but then again, I don't intend to throw money away
;-)

As a side note, I had not visited rao in a long time, did not realize
what wasteland it had become. Some of the reactions make Zip (may he
rest in peace, just found out) seem like he was a master diplomat.

Thanks

A pro amp that is rated down to 4 ohms is a bit of a lightweight. *Real* pro
amps have 2 ohm ratings. Seriously.

However, ribbons are generally thought to be pretty easy loads, in that they
are as you say often mostly resistive, and its highly reactive loads that
give cheap amps audible tummy-aches. 6 ohms should be no sweat. The gotcha
with ribbons is usually the need for lots of power. They are a relatively
inefficient lot it is hard to get lots of turns in a strong magnetic field
with a ribbon design.

Now, even
though I'm looking for cheap, this should not be construed as my not
being willing to pay what is required for a good amp. I just do not
feel the need to pay _more_ than more needs require in this area. Now
the ribbon is crossed over to a line array of Seas drivers at 225 Hz,
so needless to state the amp will be dealing with most of the midrange
and all of the treble.


Last time I heard a pro amp doing a credible job of driving ribbons, it was
a QSC USA 1300.

I will not sacrifice these areas for the sake
of saving money, but then again, I don't intend to throw money away.


Try eBay. USA 850s and 900s are the most common "find", usually closing
around $200. Will 375 wpc or so do the job for you? How much does it take to
damage that ribbon? It would be good to not be able to go there.

Default Pro Amp suggestions for subs and ribbons

Is a pretty large ribbon and if I remember correctly it is rated up to
400 watts. You are right about it being an easy load, if I remember
the graphs correctly it never droped below 6 ohms and had an easy
phase. It was virtually a resistive load. This is why I was thinking
I might get away with a proamp that was not necessarily a top proamp.
That being said, I'm not going through all the trouble of working on
my hometheater to use an amp that is going to be suboptimum. Price is
not an issue, but being practical, I don't like throwing away money on
audio jewelry. Quality and reliability are what matters. The one
thing that concerns me about pro amps is fans though.

The owner of the USA 1300 I mentioned has his amp mounted in a console right
between the two speakers. He used a resistor to slow the fan down, as the
heating during audiophile use is only a tiny fraction of the worst that the
amp is normally prepared to handle. Sound quality is excellent. The owner
has a similar approach to yours. He's got the money to spend, but he doesn't
want to spend it foolishly.

Is a pretty large ribbon and if I remember correctly it is rated up to
400 watts. You are right about it being an easy load, if I remember
the graphs correctly it never dropped below 6 ohms and had an easy
phase. It was virtually a resistive load. This is why I was thinking
I might get away with a preamp that was not necessarily a top preamp.
That being said, I'm not going through all the trouble of working on
my hometheater to use an amp that is going to be suboptimum. Price is
not an issue, but being practical, I don't like throwing away money on
audio jewelry. Quality and reliability are what matters. The one
thing that concerns me about pro amps is fans though.


The owner of the USA 1300 I mentioned has his amp mounted in a console right
between the two speakers. He used a resistor to slow the fan down, as the
heating during audiophile use is only a tiny fraction of the worst that the
amp is normally prepared to handle. Sound quality is excellent. The owner
has a similar approach to yours. He's got the money to spend, but he doesn't
want to spend it foolishly.

Last time I heard a pro amp doing a credible job of driving ribbons, it was
a QSC USA 1300.


What about your beloved Mackies or the new Behringer amps. If the
Mackies are good candidates I could place a resistor in series with
the fan to slow it down and reduce the noise. The Behringers I
understand may be copies of the QSC and could be had for $300.


Try eBay. USA 850s and 900s are the most common "find", usually closing
around $200. Will 375 wpc or so do the job for you? How much does it take to
damage that ribbon? It would be good to not be able to go there.



I think 375 he should be perfect. I would never listen to it that
loud, but it would have more than sufficient headroom for peaks and
the ribbons should easily handle it. BTW, I seem to remember reading
some negative stuff on the 900s, but I'm not sure.

Thanks for all your insights.

BTW, years ago we had a couple of discussions in RAO about blind tests
and I was not in total agreement with your total dismisal of sighted
tests. Even though I still don't totally agree (I think they
sometimes can be used to determine if further investigation is
warranted), I can now see why you were so fervently against it. For
many sighted testing is the measure, especially in RAO and some
magazines I no longer subscribe to (could not take it any longer).
What is really dissapointing though is the level RAO has droped to.
It caught me totally by surprised how my inquires were used as another
excuse to debase any form of discussion.

Goyo

FWIW I've been using a Samson S1000 as a test bench unit for testing
loudspeakers for a couple years. Thus far it's been able to drive any speaker
that's passed through here to full output at low frequencies (including several
electrostats and a couple passive subwoofersd) with no trouble. Indeed it has
been running nearly continuously for two years; IME it's quiet, reliable with a
usable feature set (adjustable level controls; rca- TRS- XLR inputs and dual
banana outputs on 0.75-inch centers.) And it sounds exactly like all my other
amplifiers. Bravo.

Thanks Tom. I have been trying to get a handle on them. I was
troubled by their lack of 2 ohm rating, and their tech support (at
least the couple of people I have spoken with) do not seem to have
much background as techs. But some of their data looked good and the
guys at SVS subwoofers seemed to like them (at least the model you
use). Thus my interest on the F1200. According to Samson it is
sonically identical to the S1000 (i.e. that have not crippled it in
any way), the former has greater bandwith (its rated to 50Khz as
opposed to 20Khz) and power, but the latter has nicer features and
higher damping factor. The differences not withstanding, I think I
may be correct in assuming the greater bandwith and lesser damping
factor should have no sonic effect. So it all boils down to is it the
same quality as the S1000, and herein lies my dilema. The people
telling me yes are the same techs I found wanting in other areas

Sounds like a good start (no pun intended)

on the QSCs. The Mackie puts the fan at the base of a horn that is pointed
right out the front of the amp.


I see, that is why you always mention the fan noise. From your
experience with your own 1200, would a resistor slow it down enough to
mitigate the noise, or do you feel it will always be a potential
factor (especially in quiet scenes/music moments)?

The Behringers I
understand may be copies of the QSC and could be had for $300.

I did not care much for Zip's reactions in the later years (I found in
his early years he could be a pain, but he also seemed to have more to
contribute), and I think that may have been part of the reason I moved
to other forums (e.g. Basslist), but now the area has become a virtual
wasteland engaged primarily on adhominems and reproduction of the same
story time and time again.

It is sad to see, but I guess it is also to be expected considering
the medium.

Again, thanks Arny and thanks Tom (love your work on subs, especially
the article dealing with your DIY basement sub).

Goyo

Default Pro Amp suggestions for subs and ribbons

Thanks Tom. I have been trying to get a handle on them. I was
troubled by their lack of 2 ohm rating, and their tech support (at
least the couple of people I have spoken with) do not seem to have
much background as techs. But some of their data looked good and the
guys at SVS subwoofers seemed to like them (at least the model you
use). Thus my interest on the F1200. According to Samson it is
sonically identical to the S1000 (i.e. that have not crippled it in
any way), the former has greater bandwith (its rated to 50Khz as
opposed to 20Khz) and power, but the latter has nicer features and
higher damping factor. The differences not withstanding, I think I
may be correct in assuming the greater bandwith and lesser damping
factor should have no sonic effect. So it all boils down to is it the
same quality as the S1000, and herein lies my dilema. The people
telling me yes are the same techs I found wanting in other areas

What about your beloved Mackies or the new Behringer amps.


Another friend of mine who builds his own ribbons has a Macie M1400.


Sounds like a good start (no pun intended)

That can work, although the base fan noise seems higher on the Mackies than
on the QSCs. The Mackie puts the fan at the base of a horn that is pointed
right out the front of the amp.


I see, that is why you always mention the fan noise. From your
experience with your own 1200, would a resistor slow it down enough to
mitigate the noise, or do you feel it will always be a potential
factor (especially in quiet scenes/music moments)?

The Behringers I
understand may be copies of the QSC and could be had for $300.


I've heard people say nice things about them, but I don't know anybody who
has one.

Try eBay. USA 850s and 900s are the most common "find", usually
closing around $200. Will 375 wpc or so do the job for you? How much
does it take to damage that ribbon? It would be good to not be able
to go there.


I think 375 he should be perfect. I would never listen to it that
loud, but it would have more than sufficient headroom for peaks and
the ribbons should easily handle it. BTW, I seem to remember reading
some negative stuff on the 900s, but I'm not sure.


People like to **** on em because they do a lot of humble work. They are
clean and they last.


That is good to know, the more options I have the better off I'll be.

Believe it or not, one stated goal of this running crapmouth act on RAO is
to get me to stay away. The good news is that there are a goodly number of
other audio groups.

Your comment about the group being a lot more civilized in the days of Zippy
are regrettably quite true. The irony is that some of these creeps were
friends of Zippy.

Last time I heard a pro amp doing a credible job of driving ribbons, it

was
a QSC USA 1300.

It caught me totally by surprised how my inquires were used as another
excuse to debase any form of discussion.

That may be, but you may be disappointed in your choice. In my experience,
the Sampson and the QSC are not first-rank amplifiers. There are better
professional choices: Crown and Hafler come to mind.
