Thanks for the detailed response. Have you heard the garage1217 amps personally? Maybe some comparative impressions?
My main gripe with the LYR2 is that its price is double compared to the garage1217 for example. I don't plan on upgrading the headphones anytime soon so don't have to future proof. Just thinking if the LYR2 will be overkill (4W at 50 ohm) or if the Garage1217 will be slightly under-powered (2.4W at 50 Ohm). I listen at high volumes. If the Garage1217 is not underpowered, is the benefit of the LYR2 justfiable with regards to double the price? In the middle of course is the Gustard H10 (2.7W at 50 ohms). Priced closer to $300 on massdrop, but not enough tweakability like the Garage1217 where I can even tame down the highs a little bit if I wanted.
When you say tube sound in a solid amp for the Garage1217, do you mean it colours the sound in some way? I'd like a more transparent amp which does not sacrifice any clarity, soundstage or separation which people say sometimes happens with tubes.
Just bouncing off thoughts to see if I'm in the right direction with this.
Nope, I have not have the pleasure to extensively listen to the garage1217 amplifiers or do any comparative impressions. there were quite a few he-560 owners here that opinions I strongly value that posted impressions. I think maybe head-fier
@Stillhart posted very detailed impressions but may have been someone else. I know on the Project Ember thread they are all very helpful, and may be able to lead you to a link with a good review better.
The Lyr 2's power specs is overkill for the HE-560 in my personal experience. I have had pretty good success with lower powered amplifiers pairing with the HE-560. It does give you peace of mind though that any sonic issues you run into is definitely not due to lack of power.
2.4W is more than enough for the HE-560 even if you are accounting for excess headroom. I believe the calculation for power requirements on the HE-560 turn out to be 0.550W. People then go and recommend 1-2W for excessive headroom. The up to 4W recommendation is due to Audeze having that range posted on their website, but 4W is unnecessary to maximize your sonic performance (from my personal experience & in my opinion).
The Polaris is tuned to sound like a tube amplifier even though it is a solid state. That is all I meant by that comment. Both the Lyr 2 and the Ember uses tubes in their design, so the sound will be inherently colored a bit. I have not found the Lyr 2 to be lacking in clarity, sound stage, or separation (even compared to solid state amplifiers). The Lyr 2 does impart a slightly warmer sound to the headphones. I do like this effect on the HE-560 particularly for my own personal tastes.
There are tubes that are less warm and more 'clinical sounding.' Really depends on your own ears what will be the most enjoyable combination to you. The Gustard H10 has gotten very positive feedback from members I trust here as well (
@conquerator2 can comment more about that specific pairing)
All three options are extremely highly recommended, so it is unlikely you will go wrong with any of them. I'd say if you have a strong interest in tube rolling, the Project Ember would be the best fit. If you only want solid state equipment, the H10. I own the Lyr 2 and can vouch for its strong performance on the HE-560, but I think all three options will most likely give you very similar good results, so really up to you!
edit: oh yes, Jeremy at Garage1217 offers amazing customer service. I've hit him up quite a lot with questions while I was deciding myself and he was extremely friendly & answered all my questions despite not being an actual customer yet. Schiit also is very prompt with their responses, though Nick at Schiit has a very curt short response style. No experience with Gustard's customer service, but if you purchase from massdrop, the people at massdrop always have taken care of me if I run into any issues.
because of different versions on the used market or bad quality control?
because of both I think. There are quite a few different revisions of the Audeze headphones, but reputable sellers will always specify. Audeze has run into quality control issues in the past with their line-up. I personally wouldn't be too concerned about that second part though. I believe they offered driver replacements to people who had issues.
