post #16 of 159

Lowering the treble certainly takes shrillness out of badly remastered CD's, particularly over-bright high strings and some female vocals, but have not had much use for moving the mid and bass controls.

We should have this stickied to the top post :)

I believe you guys after doing some research about the subject and moved my sliders to top. everything sounds louder lol, but haven't really noticed any sound quality changes.

 

lol this article seems to suggest that bottom is neutral: http://headfonics.com/2012/01/bravo-audio-headphone-amp-series-part-2-the-v3-ocean/

 

wish the bravo v3 came with instructions lol.

 

does anyone have contact information for this company? the e-mail listed on their website is invalid or my e-mails are being spam-filtered by them.

That was the only mention of the EQ that I could find before getting my V3. I linked it in my mini review in the other thread. It's definitely the opposite of what the author said.

So where you guys think is the best place to position the slider of the eq? Middle position on all low mid high?

@Didhefocus - which position in the eq slider you think will the stock v3 sound close to the sound of your modded v3? Great work btw!

The choice of tube will play a role also. The guy who wrote that article was using the stock EH 6922,which gave him a V shaped sound. More neutral tubes might require different equaliser settings to achieve the best sound for you. That's the fascination of the V3.

Thanks for the quick reply HOWIE13. I am currently using the stock russian 6922EH tube whick i think focuses on mids. Or maybe that is the sound signiture of the v3?

You're weIcome! I agree the 6922EH is mid/lower biased in my system, and is a good, dependable, all round tube, particularly for forward vocals. Much depends on your kit and musical tastes though-not  to forget our different ears of course-LOL!

Thanks, all sliders at the top sounds closest to bypassed.

Bypass switch installed!

I now have the ability to switch the EQ in and out instantly. I haven't committed to drilling a hole to mount the switch permanently yet but I came up with a fairly good temporary solution.

 

Upon listening, the first thing that's obvious is that there is an instant drop in volume but listening carefully reveals that the midrange and bass are suppressed and treble is almost untouched! Mid-bass is really suppressed so it gives the impression of reduced dynamic range.

 

As the reviewer said here, http://headfonics.com/2012/01/bravo-audio-headphone-amp-series-part-2-the-v3-ocean/, he preferred the V2/Ocean for the midrange warmth. He also said that " uber bassheads" would like the V3 better. I somewhat disagree since mid-bass is what most bass heads go for IMHO and the V3 in stock form doesn't have much.  

 

With the bypass switch installed, I now think I have the best of both models!

 

Some pics of the install.

@Didhefocus

Fantastic work and great pics.

Just to clarify-do you mean that even with all the levers in the top position there was an increase in volume, mid and bass once you had bypassed the whole EQ circuit?

That would mean that the equaliser filters, even when off, were clearly affecting the sound in a major way.

Thanks and apologies if I should have understood this from what you have already written.

Thanks Howie, Yes the EQ does affect the sound a lot even with all sliders set to flat (up position). Not only is the frequency response altered, gain is reduced limiting the output for less efficient cans!

That's so helpful to me. I listen to a lot of Classical, which is often recorded with lower volumes and with a wider dynamic range than modern music. This means that some 250-300 ohm cans can struggle to be loud enough for my liking.(which, admittedly, is very loud LOL!). I am hopeless with soldering but I have a friend who can do the mods for me, thanks to your clear photos. Thanks again.

My old Yamaha HP-2s are 150 ohms and not very efficient. The Bravo with the EQ at center or below didn't have enough gain to drive the HP-2s very loud at all. The Bravo amps have plenty of power but it was the gain lost by the EQ that limited the output.

Very nice and neat Didhefocus! Any plan of replacing better capacitors? Will there be a better improvement when you replace the stock capacitors with better one instead of rolling tubes?
