Currently analog, rotel rc-06 preamp,rb1090 amp, oppo 980h,kenwood kt5020 tuner and pioneer pl-518 table. This is the system I put together when I got my polk sda 1b's about a year ago. Now that I have the A7's I'am looking for at least a tube amp to safely drive them. Any suggestions?
Here's one it is not new in the box though.There are new ones for 1-2 bills.

Problem with 10 band is each band is an octave...not very precision.
Honestly, my favorite EQ, at least affordable one, is the Altec 1753 A/B
They can be picked up as low as 50-60 each, you would need 2.
The Behringer DEQ mentioned is good. Stay away from the cheap Behringer.
Again not new, but RANE ME60's can be picked up for 150-ish
Most decent EQ's are 400+ new
Your neighbors called. They like your music.
Graphic equalizers come in two distinct flavors; variable-Q and constant-Q.
Constant-Q
Years ago (before modern audio analyzers) an audio manufacturer made a name for themselves and convinced many that the constant-Q was the way to go. This type of eq paints a very pretty picture on a 1/3rd octave audio analyzer. The filters are very steep and choppy at boost/cuts less that 6 - 8 dB. More boost/cut and the filter looks like . . .
Variable-Q
All of Altec Lansing equalizers (up to and including the "programmable" 8000 series) are variable-Q. Each filter overlaps the adjacent filters. The more you boost/cut, the more frequencies are affected. Gentle boost/cuts are suggested. In fact, most recommend cut only for a playback system.
The 1753A was the last 1/3rd octave eq offered by Altec and it is nice piece. A pair of Altec 1653 equalizers would be worth big-time bragging (1/3rd octave, cut-only).
Please keep in mind that most Altec electronics were sold and used for professional/commercial applications. Most used units have likely been running since they were new and they typically start having contact/component issues after ten years of steady use.

Ditto on the Rane. Ashly, too makes good sounding EQ. Stay away from the old Klark-Teknik stuff! Awful sounding. I didn't know how bad until we swapped it for an Ashly. Maybe their new stuff is better.
Have never used the Altec EQ. Think I ran Urei for awhile - did they make an EQ?
EDIT: Here is a good deal on a 1653.

You'd need another one for stereo
Oh wait! This guy has 2 - 1 not working. With above you could have a pair for not much coin.

Odd- Altec claims the 1753 is constant QOriginally Posted by whitebroncoii
Are you sure about that?

Wouldn't be the first time an error on a spec sheet, but that is a big one.

OG, thanks for the spec sheet. The cool thing I noticed was a 0.7V nominal level. Great for home audio!
Yes, ditto on the ME60, 1/3 octive from 25hz to 20K. I picked one up a few years back to replace my ailing Altec 729A Acousta Voicette, that I had in continous service for 30 years. After Iratec brought the 729A back up to spec, along with a couple upgrades, I've gone back to it. 1/3 octive from 63hz to 12500. I like that it takes out, and does not boost, then compensates with a broadband reinsertion gain. BUT, just try to find one of those in good operating condition.
i like my white 4400s w/ no trannies/crossovers....
4400 - Retired Product - White Instruments Div. C Van R, Inc.
perhaps a purist would prefer the 4000 ( i think??? could be wrong) series
(if not, i meant the cut only versions)
they do pick up hum/noise from close electrical components (read amps) though...
requires some distance from other equipment IME....
or i can run it in the loop of a Urei 1620 preamp/DJ mixer and it seems quiet too...
good luck,
try to audition other friend's gear, if at all possible, is all i can say!
*EDIT*
darn, posted after reeading only a page of posts...
sorry for the repeat!
parametrics are nice too. agreed!

No, I was wrong. Please forgive me for my failing memory and thank you for the correction. The 1753A was an attempt to get on the constant-Q band wagon. I guess I really do not recommend this model . . .
BTW: The way to tell for sure if an eq is constant-Q is to look at the graphs showing boost or cut in increments. A constant-Q filter will always have the same "slope" and the base width changes (see the 1753A data sheet). Imagine how your response would look with 3dB of cut on every slider! It would look like a saw blade.
