Violectric HPA V281 - Vorsprung durch Balanced - updated with photos and power specs - first...

post #1 of 418
Thread Starter 

preliminary brochure http://violectric-usa.com/download/V220-V281%20Preliminary.pdf

 

 

 

 

Here we fill in all info we get for the V281. Prototypes at the High End 2014, estimated first shipment: June 2014. Feel free to add info and I will update the OP with better info and pictures

 

 

  • using V220 as base design and concept for balanced goodness
  • optional remote control with motor-driven ALPS RK27
  • true preamplifier with options to mute (headphone/Line ON/ON, ON/OFF, OFF/ON, BOTH OFF :evil:)
  • 4 Pin XLR balanced output for headphones
  • 25 Watts toroidal transformator
  • 3 inputs: balanced XLR, unbalanced RCA, optional digital input, all selectable from the front or remote if installed
  • optional inputs: USB, optical/coaxial 24/96 or 24/192, the latter based on PCM 1798 D/A section and more sophisticated analog circuits
  • balanced and unbalanced outputs, pre/post fader option thus variable or fixed output
  • volume control: ALPS RK27 potentiometer or motor-driven per remote RK27, or 128 stepped (0,75db per step) relais
  • relais volume control for the absolute best channel balance, step precision, ultra low distortion, and lack of crosstalk, absolute zero scratching to be expected
  • L/R balance controls +- 6db
  • clearly better than the V200
  • measurements approximately 165 x 114 x 310 mm / 6,5 x 5 x 12
    inch (W x H x D).

For a better comparison we added the data from V200.

Wowza, that's a small fortune for this thing, still...i'm interested

post #3 of 418

This is going to be the amp of the year!  Can't wait for it

Will u be starting a pre order list?

I don't know yet if they want to do such a thing on Head-Fi, I've just asked about it. There is huge worldwide interest on these though so they'll be quite busy.

post #6 of 418

any hint on the v220 pricing?

 

looks like the v282 is going into really competitive waters with that price tag

 

i like the extensive work done to improve usability in the input/output section, and the pot options are really exhaustive, as well as the upgraded dac options but i'm more interested in the new standalone dac offerings

 

any hint for the upcoming dac devices (v800 successor)?

V220 will be around 1000€ basic and more depending on your upgrades. No news about V800 successor, I guess the USB option will be upgraded first before any new model.

 

*updated the OP with more pictures and new prices* (thank you Arthur!)

Oh boy... dilemma. Wait for the new V220 or get a V200?

Here is some info i posted in the v200 forum earlier, but since Fegefeuer asked to repost:

 

I was in touch with Fried Reim in December and i asked him about the new amps. I hope he doesn't mind, if i share  it with you guys.

 

About amps to come ...

 

We are working on successors of V181 and V200, named V281 and V220.

To save costs V220 will be the base of V281.

 

They will have double height cases so 2 "standard" units will meet the height of the new amp(s),

also the cases might be a little deeper.

The basic V200 circuitry will remain and will be implemented into the balanced V281.

The transformer will be bigger to have a bit more amp-juice and the ability to feed some nice options.

The inputs (balanced, unbalanced and the optional digital input) are selectable from the front.

There will be a (balanced ?) line output on the back.

This can be set to be adjustable or fixed to the input source.

The basic version will have a manual volume control and a manual balance control.

1st option is the remote control with motorized potentiometer for the volume and for input selecting.

2nd option is a 128-step relais based volume, also together with the inputs remote controlled.

Finally 1 of 6 digital input options may be chosen: USB/Opto/Coax with up to 96 or 192 kHz sample rate.

 

We hope to release these new amps middle of 2014.

 

Also there will be some nice priced but high featured Lake People DACs to be released soon

to establish Lake People even more as a "budget" solution under Violectric.

 

Well, I'm waiting for the v281 without question

Wait is my advice...if you can :veryevil:  At the very least the prices of the V200 on the used market will come down substantially.  I'm sticking with my V800/200 combo, have a speaker amp under way to power my hungriest beast (HE-6, the 200 powers it well but there's better to be had from even more power, curious about the specs on the upcoming model).

 

Very happy with Violectric but with the new pricing they're entering in some serious heavy hitters' water, I'm very curious to see how the new units will stack up.

 

Anyway, thanks for the info, I'm subscribed!

post #12 of 418

Nice!

 

I thought the V281 was dead in the water for not hearing anything about it for so long.

 

I even made a speculation thread about the V281 back in 2011!!!

The balanced one looks very promising!

 

Is there an early adopter pre-order bonus program??? :biggrin:

YEEES, sell yours v200's on the used market !!!! wink_face.gif

For those lacking the virtue of patience (I'm a platinum club member myself):  take a look on amazon.de

 

If you hunt patiently you'll find an attractively priced one for sure, they pop up regularly there.  Or at thomann.de , they regularly clean house of demo units and it's possible to get a hefty discount.

post #15 of 418
Too bad I have to stick with amazon.fr !! I see good other deals on amazon.com also but I can't order, RESTRICTION ph34r.gif

Agree thomann is a very good store around here but I only see B stock to get the v200 less expensive

Can't wait anymore !!!
