Amp Options
 

Almost purchased a Brax amp. What I didn't care for was the size. I will check out Sinfoni, Butler, and Zapco amps. The amp size must have a small footprint.

I will likely need to bridge the rear for two small (6-8") subs I plan to located in the rear hatch where the foam piece is locate. I am looking into a Audison Bit Ten (it's a smaller version of the Bit-One with only 5-channels instead of 8-channels) for its tuning aspect sometime down the road.

Do you have any experience with any of the suggested amps and a Bit-Ten?

The audison and zapco I have the bit-ten never heard of that one.

Bit-Ten
 

A bit-ten is a tuning signal processor (not an amp) similar to the Bit-One manufactured by Audison. :tup:

Got ya

Burrbrown is now a division of texas instruments, and that division of ti is simply the best in terms of audiophonic IC construstion. BB is the intustry standard for operational amplifie circuits in terms of their entire line of parts and such. Many repair techs will pay the 30x premium for BB over other opAmps made in China or even from Texas Instruments. BurrBrown components can mainly only be found in the highest of the high audio equipment mainly in home audio, but is also the primary device used by engineers in their reference designs. Often times stumped by Acountants who prefer cheaper parts for making higher profits.

you can pay someone to upgrade most amps and processors with BB parts but the cost is usually not worth the trouble.

as far as I know for car audio BurrBrown is found in Zed factory upgraded amps and not many others.

Zed Audio amps
 

I will have to check the Burrbrown (BB) options from ZedAudio. I know it was an option in the past. What's the longivity of the BB componets?

They dont un-necesarrily burn out. Any good quality built amp should last for years and years as long as its hooked up and tuned properly. I'm sure amy amp in the category you are looking after will have longevity. The difference between BB and using generic branded ICs is the quality of build in how it relates to the quality of sound. Only some of the elitist of audiophiles ask for them by name. If you get BB parts you should be able to tell when the music is completely silent (no hissing on a blank track unless induced by head-unit or processor), and warmth/depth/fidelity/control at the highest of volumes.


For my repairs, I can pay $0.75 per opAmp for the TI or chinese equivalent, or spring for the BurrBrown parts which can run up to $20 a piece. Most amps have several to dozens of these parts.

Here is a good read on opAmps. BTW, the opAmp is the the first device in-line with any amplifier's pre-amp circuitry. If its a piece of junk (I've seen many in Amps which were never intended for Audio) then its probably not going to make the rest of the amp sound good.

Opamp: Burr-Brown option on Zed Audio amp
 

I will check out the Burr-Brown option for a ZedAudio amp and post back.

Here is another sick amp!!

:: Ground Zero :: Amplifier / GZPA Reference 4

ZEDAudio amps
 

ZedAudio does not have the Burr-Brown option anymore. According to Stehphan (ZEDAudio) The chips in the current amps are similar to the Burr-Brown chips.

Have you decided where you want to install the amp?
It helps to know what to shop for size wise.

As for Hertz and Audioson... Parent company is Ellettromedia.

They are Italian owned and manufactured.

Hertz HDP amps seem to be built solid. They were going after JL HD class business. and they wanted to be lesser priced then the JL amps. They have achived their goal.

Amp Location
 

I'm likely installing an amp in the rear hatch where the foam piece is located in front of the spare tire.

How does the Hertz amps compare with the JL HD amps?

I haven't done an A and B comparison. we will be putting one on the demo board soon, we will be able to evaluate soon. Of course I would rather have it in a car.

I would say hertz amps would be better than JL. Keep in min JL is a lot more hype and way over priced for their products.

Look foreward to the JL Audio HD vs Hertz amp comparison.:tup:
