hey cld someone please explain to me the differences between the different Garage1217 projects (starlight vs sunrise 2 vs ember)? I read the full descriptions for each one but it all sounds like mumbo jumbo to mee lol. I need it explained in practical layman terms =S
I got that project horizon is for high impedance headphones specifically with more power... but I am not sure what is upgraded jumping from starlight to sunrise 2 to ember.
please helpa noobie
Basically the ember has more power and more customizability as far as resistance and gain settings that affect sound
I have Ember, PS2 and Starlight so here goes:
Starlight:
1. Accepts higher heater current tubes than Ember.
2. Uses opamps in the output stage. There are two sockets per channel--the amps are "paralleled" so that all four (two per IC) outputs combine. So you take the output spec (data
sheet) and multiply by four to get your output current. Because they are in sockets, you can roll the output section like the tube. Because it is not Class A operation the output section
runs slightly higher than room temp.
3. Low (1.5 ohm) and high (68 ohm) output resistance settings.
4. Manual bias setting via LED.
5. Starlight is the entry level amp--it has a single color LED under the tube--the others have three color adjustments.
6. Runs on 24 volts.
Sunrise 2:
1. Accepts higher heater current tubes than Ember.
2. Output resistance selection 5 and 68 ohms.
3. Manual bias setting via LED.
4. Class A output section--runs very warm but not hot--don't touch.
5. Runs on 24 volts.
Ember:
1. Easy tube rolling--just plug tube in and it determines the heater voltage automatically--BUT--it can't take higher current tubes like Sunrise 2 and Starlight.
2. Opamp output section--low heat output.
3. Three output resistance settings--.1, 35 and 150 ohm.
4. Normal and high (+6db) gain tube settings.
5. Has enough power to run any dynamic headphone so far. Because of this it runs on 48 volts.
