Headfonics will be doing a review of these sub $100 tube amps shortly!

Bravo Audio

v1/v2



v3

Guitar Booster

(for guitars!)

Bravo Audio and Indeed share the same design concepts but what I am  currently enjoying is the Bravo Audio V3 with hard EQ and discreet mechanics.

The Tubes are 12AU7 so plenty of rolling potential.

Stay tuned on this - we may have a distributor in place for this for local orders as well if they prove their worth and right now for under $100 I think they may be a bargain.

v1 v2 looks like the indeed g2 amp hehe cool!

[Racio]

Oh wow! O_o 12au7! Could you give us a preview of their specs bro, power output in particular?

[Panzimus]

Will be waiting for the review marcus. I wanna know how it will synergize with Grados.

[Boymasskara]

that V3 looks yummy but i'm scared that the circuits will gather dust in my room easily

Signal/Noise Ratio   >90dB
Dynamic range    84.6dBA(300 ohm) 89.8dBA(33 ohm)
THD    0.016%(300 ohm) 0.45%(33 ohm)I

I suspect they can all take the same tubes but the others come with Electro Harmonix 6922 tubes.

correction the Ocean takes a 12au7

I think Ken has had one of these for a while now

He has the Indeed G2. I spoke to the guys at Bravo and they mentioned that Indeed are shooting for power and they are going for sq hehe... but the V3 is the one that has caught my attention so far. Yet to try the others but hard EQ on a translucent tube amp the size of my hand is kind of neat

^How come they've covered almost everything in their spec sheet except for the all important output rating?

Well I am currently using an ESW9 on the V3 and its on 9pm on the dial so plenty of potential - will hazard a guess and say maybe 600-1w.

Will go up to the hifiman's tonight.

They seem like a good solution for da office. Indeed, they DO look like the Indeed.

Same blueprint for the see through ones, the aluminum encased one though is their own paid for design (Ocean).

Now using the HE300 dynamic headphone and comfortable listening on the V3 is 9.30pm so still power to be explored. Had to tone down the eq from the esw9 setting - less bass, more mids and same treble.

[marcusd]

Ok this is interesting - on the V3 with some eq in favor or bass, mids and rolled off highs the Hifiman HE4 is sitting comfortably at 12 noon with some 320k Mp3 from the ipod nano through an LOD to RCA. 

Not the thickest richest of sounds but pretty decent.

If you get an extra one, I'd gladly test it out and review it. I will also be able to do an informal comparison against prawncrackers Kraken amp
