Hey guys. Post your reviews/thoughts/comparisons of the Lake People G109 and G103 here.
 
Thanks!
 

 

Lake People G109

There are two versions, the only difference being the inputs:
 
G109-S Unbalanced RCA inputs only ~ $450 USD
G109-P Unbalanced RCA inputs and Balanced XLR inputs ~ $500 USD
 

 
 
The PHONE-AMP G109 was developped with the
target to enable highest transmission quality for
low- , medium- and high-impedance headphones.
Some features:
- Electronically balanced inputs
- Unbalanced inputs with priority
- DC coupled amplifiers (switchable)
- PRE-GAIN: Overall gain switchable in 3 steps
- NF trammission band exceeds 150 kHz (-3dB)
- High-grade volume control ALPS RK 27 with
  optimized channel balance and lowest crosstalk
- Toroidal transformer, large smoothing capacitors
- Discrete amplifier design
- Outputs with relais controlled switch-on delay

The inputs are situated on the rear panel, they are
equipped with electronically balanced XLR connectors
and unbalanced RCA connectors.
Volume control is provided by a large full metal
rotary knob. Two headphones may be connected
via 1/4" jacks on the front panel.
The unit offers a built-in power supply with IEC/CEE
socket.
The complete case, front and back panels are made
of black anodizes aluminium.

Lake People G103

There are two versions, the only difference being the inputs:
 
G103-S Unbalanced RCA inputs only ~ $250 USD
G103-P Balanced XLR inputs only ~ $300 USD
 
 

 
 
Headphones amplifier with highest transmission quality
and compact dimensions to drive 2 headphones.
The PHONE-AMP G93 is optimized to lowest noise and
distortion.
The featurs:
- electronically balanced inputs
- four gains switchable: -4 / +2 / +8 / +14 dB
- NF trammission band exceeds 150 kHz (-3dB)
- Alps volume control with good channel balance
and low crosstalk
- powerful amplifiers

Because of ist variable gain structure G103 is best
suited to drive low- to high impedance headphones
(16 … 600 Ohm)
The inputs are situated on the rearpanel, they are
equipped with electronically balanced XLR
connectors. A rotary pot on the frontpanel is provided
for level control. G103 is equipped with two
headphones outputs with 1/4" jacks.
The unit offers a built-in power supply with IEC/CEE
socket.
The complete case, front and back panels are made
of black anodizes aluminium.

G109-S Unboxing

I received my Lake People G109-S yesterday via UPS Express Saver International from Germany. It arrived just 48 hours after placing the order with Lake People. Very impressive. Here are some unboxing photos.

230V vs 115V

 
If you will be using your amp in the U.S. or places that use 115V AC mains power you'll want to buy the amp directly from Lake People or through their U.S. web store: http://violectric-usa.com/
 
Amps purchased through Thomann.de are set to 230 V AC so in order to plug them into 115 V AC outlets in the U.S. you will need eo either use a step-up transformer or modify the amp. To convert your Lake People / Violectric amp from 230V AC to 115V AC or vice versa, see these instructions provided by Fried:

How To Buy

 
For those who are interested, I got in touch with Lake People and found out the following:
 
You can order the G10X amps direct from Lake People by emailing them at info@lake-people.de (don't forget the hyphen). You will get a 5% discount which will make the prices as follows:
 
(Current prices as of Aug 2012)
 
PHONE-AMP G103-S = 195,59 EUR
PHONE-AMP G103-P = 235,51 EUR
PHONE-AMP G105 = 294,50 EUR
PHONE-AMP G107 = 351,50 EUR
PHONE-AMP G109-S = 355,25 EUR
PHONE-AMP G109-P = 395,17 EUR
 
Shipping to the US is 32 Euros for a single amp. Amps shipped to the US are set to 115 VAC mains voltage. Payment is done through PayPal. Shipping was *extremely* fast for me and Lake People's customer service was spectacular.
 
 
NEW: It looks like Lake People / Violectric have a new U.S. web store that you can order from as well:
 
http://violectric-usa.com

Devhen have you figured out a source for US Customers?
 
I'd like to get my hands on one of these unbalanced units.... But no luck finding a merchant that sells to US.

 
Yes! thomann.de is where I plan on getting mine. Go here:
 
http://www.thomann.de/intl/lake_people.html
 
Add the amp to your cart and change the shipping address to the United States. It will add a $30 euro shipping charge. After that you can click the american flag in the top right corner of your cart and it will let you change it to USD if you want to see the total in USD. Their prices are pretty good even with the additional US shipping. Their shipping policy states that shipments to the US are fully eligible for their 30-day money back guarantee and their included 3-year Thomann warranty.
 
Apparently these Aphrodite Cu29 guys are the official US distributor for Lake People but they still don't have any Lake People amps listed on their site aside from the Violectrics:

Thanks Devhen, I also just got contacted by Lake People directly. They said to send requests to info@lakepeople.de
and they can process through paypal direct from the shop. or contact Aphrodite music as he can probably process the order through the shop in Germany.
 
Super glad I saw this post. Without naming names, I was looking at two other $250 to $300 amps and was about to pull the trigger.... way happier with this choice.

Awesome! Thanks for the info! I think I'll email them and see if I can get a quote on the G109-S.
 
Feel free to name names. :) But yeah in the $250 range the G103 is looking like it might be a really awesome bang-for-your-buck amp.

Maybe try again on Monday, he said there would be no activity this weekend....
I was looking at the M-Stage and a Yulong model.... Based on the review you posted, I think even the low end Lake People model is more promising.... with the Violectric DNA and all.
 
BTW that site you linked has some pretty sick pricing all the way around.

@ devhen
 
try:
 
info@lake-people.de instead info@lakepeople.de
 
It´s only a " - " but it makes the difference :wink:
 
Thomann is the biggest "music" related shop in Europe.
 
They offer goood prices, 3 years warrenty and a 30-day return policy (dont know how this works outside Europe)
 
But please keep in mind that specially the Lake People and Violectric stuff is set to 230 V AC mains voltage as they normally only stock for european needs (until now ... ).
 
But it is no mystery to change mains voltage when you are common with the hot end of a soldering iron - and Lake people will send instructions !

Fried,
 
So great to hear from you! Thanks so much for the info. I was under the impression that the G103 and G109 supported both 230 V AC and 115 V AC mains voltage since the back of the units say "115 / 230 VAC" next to the power outlet. If not, would it be possible to order a 115 V version of the G109-S directly from you guys, to be shipped to the US? If that's not possible I'll go ahead and order from Thomann and make the change with a soldering iron.
 
Thanks again!
 
Devin

Hi Fried, 
I have a question about g109. The specs for the 'P' version says 'outputs with relais controlled switch-on delay' which is not there in the 'S' version specs. Can you explain what that means.

Interested if this can drive HE-6.

 
Hifiman headphones sounds pretty good on my G100, but for the HE-6 I would go for a speaker amp instead.

From the review on Innerfidelity:
 
"...at the heart of the design a National Semiconductor LM1876. This is a chip amp that is intended for driving speakers, and is popular with the DIY crowd for things like Gainclone amps."
