Mod your Beresford 7520

[ReachtheSky]

The LT1364 low current ability of 5mA made it however pretty useless in the headphone stage.

Thank for that Stan.
The LT1364 has been one of my prefered opamps when uses as the preamp chip direct to power amps/speakers.
But, I have wondered why it has not been quite as "exciting" when used in the headphone stage.
Much appreciated,
Granville

Ah right cheers, no good for me then as headphones are used almost exclusively.

Robbo,
If your speakers and amps are quite revealing then I would choose some of the faster opamp chips about.
My own preferences are:
THS4032 (with Tirna cap mod)
LT1364
AD826
Have fun,
Granville

Thanks Granville,
Hope to try all those suggestions as this MOD thing is new for me.
I need one more suggestion.
I am looking for opamp with LIGHT, fast, tight bass.
Open, forward midrange.
Crispy, sweet treble.

In my first question I asked for "tight bass and fast sound".
I forgot to mention LIGHT too, I do not need overpowering bass, that is tiring to listen (IMO).

Thanks for suggestions, looking forward to try all the suggestions.

I have the LME49720HA in the Caiman fixed / variable out and really like it. For me, it improves on the standard LM4562 with sweeter treble and more defined bass.

Thanks Chrism,

It looks like I will try most of suggestions for opamps, as I am looking for the lively, forward sound. I really like Beresford due to the fact that you can customise the output depending to your system and sound you prefer.
Hope to get hands on most opamps and will write short review.
Thanks for all on fast replies and being helpful

Hi Robo,

I’m a little unsure of what sound you are trying to achieve. IMO if your amp/speakers setup is sufficiently fast and revealing then I doubt that you will find the 7520 bass tiring with a suitable fast opamp chip. (In a lessor system that may be the case!)
The 7520 can produce great SQ if your system is up to it! Some may say that it is a little bright, but I would say that it is capable of being very fast, detailed and revealing.

If bass (and good bass) is not your thing, then don’t use the THS4032 as it has great fast, tight bass. The LM4562 may be more suitable for you. Many users suggest that it is a little bass shy!

I can’t confirm but get the impression from AoS comments that the LM4562 and OPA2134 (for that laid back sound) are a safe bet in most systems?

Being new to opamp rolling, you will be surprised at just how effectively you can modify the sonic signature from the 7520 to suit your ear!

Just experiment…that part of the fun.

Hi Granville,
I think you are right, I do have a problem with my current system, or better said, acoustics of my living room which is my listening room. Almost any speaker I placed in here was a bit bass heavy including mine. With analog sources, my system sounds fine (depends of the component of course), with digital is always hard to listen with bass heaviness. The best CD player I heard was Rega Apollo, with lively midrange, treble and not to heavy bass.
Anybody compared Beresford with Rega Apollo.
I rather have cheaper (easier to mod) Beresford (it is new for me as I just discovered an easy way of opamps upgrade) with few digital inputs (including USB) as opposed to more expensive Apollo with only CD as input.
I am happy to hear that 7520 is fast, detailed and revealing.
I just need to play with few of those opamps.
THS4032 sound appealing for me with description of fast, tight bass, I do like good bass, but I mentioned light too as my system can be touch heavy sounded with bass (that is what my ears/brain hear). I checked on THS4032 and it looks different than other chips?? How can you insert it into 7520?
I already ordered LM4562NA.
I have at the moment OPA2132PA opamps, and I do like the sound, but just wanted to hear more opamps, they are simply to replace and try, much simple procedure than buying another cable or DAC (thank you Stan for that).
I will probably try to get hands onto all of the chips suggested but THS4032 looks like a proper opamp, (by looking at a price), just not sure on how to implement it into Beresford.
I do prefer fast, tight bass, open, forward midrange, sweet, lively treble.

This opamp thing is very addictive, I am not sure if all those opamps have to be burn in and for how long?
Cant wait to try them, it is real fun.

Thanks to everybody on this helpful forum

Hi RoboCopper,
I'm amazed that you've got to your 7th post without being handcuffed & locked in a soundproof cell with a masked 'persuader' who works for the first post police here on the Art of Sound.
Before they set the dogs on you, could you just drop in over at the Welcome area of the forum to say hello to the folks?

A few words about yourself & your system would be a good way to officially announce your arrival. We like to refer to each other by our first names (even if we do have too many Daves here..............you're not a Dave are you?) We also find that our shared love of music is the thing that binds us all together, so a quick run-down of what you like to listen to is always a great way to break the ice.

If you feel like it, you could also post some pictures of your gear in the Gallery too!

Cheers

Good to see that you didn't 'waste' your 3000th post on a gentle admonishment Chris!

Welcome to AoS RoboCopper.
