My understanding appears to be confirmed by rmouser's post #22 where he provides some useful specs about a number of opamps and notes that the 4556's have an output current of 70ma while the 4562's output is 26ma.  Unless you are driving something difficult, you may want to just go with the LM4562. 

 

I just got the Starlight over the weekend and like cheaphifi notes, the amp is pretty powerful in stock L2 configuration.  It's a great little amp.  Love the "kit" look, quality of the construction, and Jeremy is great to deal with.  Now I need a small arsenal of tubes to try out for fun!  :) 

Thanks for the confirmation! :)

I think I will go for the LM4562 since I will be using 16Ohm cans and most probably not touching those 600Ohm cans

Unless your cans are really low in sensitivity you should be OK since the Starlight puts out 220mw@1.5R and 60mw@68R (R = output resistance) at 16 ohms, which should be enough to drive the cans to sufficiently high volumes.  When trying to figure out suitability, in addition to the impedance, can sensitivity is something you need to know to determine your power needs.  Let us know what you think after you get your amp.

Thanks man, that was one of the many factors in making me getting the Starlight over the PSII (i.e. since I highly doubt I will be getting higher impedance/low sensitivity cans (or even other cans?), may as well get the Starlight => Can save around 100 USD, but no RGB LED functionality out-of-the-box)

 

Just wondering, should I still get the NJM4556s as spare op-amps in the rare event that I will be using higher impedance/low sensitivity cans, or should I channel that 5 USD to other op-amps (or just get an Ember :D ) that can do a better job at driving such cans?

From a practical standpoint, I think if you start down the road of acquiring more cans and cans that require stronger amps, you're going to naturally want to buy the better amps if you have the money (maybe even if you don't ;)).  Just look at all the people who come to this forum and see how much "gear" each person has or has had at any moment in time.  That's why they say, "Sorry for your wallet!"

 

Just my 2 cents for what it's worth.

Hmmm... The most I will be getting for the next two years (or further) will be just a Q701/K712/HD600/HD650 I think.

 

So I guess I just stick with the LMs :)

You can choose between red, white, blue, green and orange.

Are you talking about about Project Starlight (the cheapest one)? I read somewhere that it didn't have the option to customize its glow.

Yes, Starlight. Jeremy (Garage1217) listed those as being available when I ordered mine.

You get to choose one color, unlike the other Projects where color is adjustable.

mmm do you think they wld b nice enough to make a starlight w/ adjustable colors... i really don't know enough about tube amps to know how the other projects improve over starlight, I really just want flashy lightssssss LOL

Just get the sunrise then, like $50 more built

heyahey just curious how the Garage1217 projects differ? Sstarlight vs sunrise 2 vs ember. Cld someone explain the difference in easy-to-understand noobie terms? :) heh

You can say that the Ember is the best model, Sunrise II and Horizon being mid-range models and the Starlight being the entry level model for starters.

 

Exact differences as follows:

 

  • Op-amp Rolling: Starlight only
  • LED with controllable colour using trimpots: Ember, Sunrise II and Horizon (For Starlight, you will need to tell Jeremy what colour you want after you place an order. Of course, if you are handy enough, you can always replace that normal LED with those from the other three models ;); am planning to do so once I get enough cash for it)
  • Impedance: Ember can cover practically anything, Horizon is more for those harder to drive headphones, Starlight is more for those more sensitive headphones/IEMs while Sunrise II is an in-between the Horizon and Starlight.
  • Tube Rolling: Much easier on the Ember since it is just plug-and-play; for the rest, you will need to do some biasing (i.e. tweak the correct trimpots so that the correct voltage goes through the tube)
  • Physical Size: Ember being the biggest, Starlight being the smallest.

@darkan,

 

thanks! that was really helpful. Now I saw on their website that they are coming out w/ a project sunrise 3. Does anyone that compare w/ project ember?
