Just got this toy to play...

After about 10 hrs of playing with RS-1... I can said that the sound from the amp is very very warm yet balance.. The Mids from the RS-1 is so much liquid smoother and plentiful.. Bass has the slam and yet not that muddy as previously new.. Going to get some better power cord..

If you don't mind me asking; where did you buy this amp and how much did it cost?
Thanks!

I like that porthole view of the tube. Cool

Is the amber light internal or is it an outside reflection?

 

[nakedtoes]

it sounds suprisely good also..

It is the internal light

 

[909]

nice

Nice!!

Those usually go for ~$200 + $65 S/H on ebay. I saw one end at $160 but didn't meet the reserve.

How is the noise, hiss and hum with those Grados? I think youre one of only a couple here to own that amp.

Yeah there are a very few of them owning this amp here actually. I searched the forum.. and during yr meets , ppl are saying good things abt this amp.....This is a very quiet and clean amp... Initially i hear hiss with my ER4S... then i change another CD.. and realise thats hiss actually comes from the recording... Now my listenable CD collections is shrinking..

You can get directly from the link i post above.. + shipping to USA i believe about USD150. that is a steal price for a headphone amp cum pre-amp. If you understand chinese can see the specs.. they are using quality parts too..

How do you power it here in the US?.. the back panel says 220V
?

This is interesting... Not too sure also.. I will try to email the manufacter

If they do not offer a 110 version, you can buy a 110>220 volt up-converters.But you need to know the current draw in amps or watts to make shure you get the right size. There is a formula to convert watts to amps or visa versa but I dont remember the formula offhand.Hopefully both use the same spec..Maybe someone else can add more on this, as I am trying to remember electronic classes that I took back in high school----we were still studying tube theory back then.Solid state was a new emerging technoligy. Oops I am giving away to much info.

W=V*A... I think

I just ran a search and it hit on these---http://www.popularelect.com/upanddown.html.
I am not advertising, just trying to find out the cost myself as I just got a email back on the pre-amp from the overseas suppliyer. I need to ask next if they have a 110 version, but I am doubting it. I was thinking about pairing one of these with the Zhaolu dac's at about 300 dollars for everything. Not bad

I used to own the 708A. I see it's up to 708B, but have no idea what the differences are. Mine was wired for US voltage. The main issue I ran into was the turn-on hum. As it powers up, there's a loud hum through headphones. Doesn't hurt anything, but it's a pain. Tuberolling can improve sound a bit, but not much. If you go too far and get really "good" NOS tubes, the sound falls apart. The rectifier tube socket uses a Chinese tube. You have to rewire that socket to use other tubes that are electrically equivalent (except that the case is too short: guess how I found that out

).

Extremely nice "tubey" sound that I really liked with ATH-W100. To me, this did for AT headphones the same thing that the Radii HAP-03 did for Sennheisers.
