I am going to buy the STAX SR-009S earspeaker, but am a novice in the high-end audio world, and need some advice selecting a full setup (amp + preamp) that won’t limit the performance of the SR-009S. My reason for this purchase is that I used to have a STAX SR-L500mk2 with an SRM-252ii amp, hands-down some of the finest products I’ve ever owned, despite being a far cry from flagship-tier. I absolutely loved the unique STAX sound signature. I have been meaning buy a new STAX product for some time. My former setup: Headphones: SR-L500mk2 Amp: SRM-252ii Preamp: Integra DHC-40.1 Preamp specs: http://www.integrahometheater.com/Products/model.php?m=DHC-40.1&class=Preamplifier&source=prodClass Planned new setup: Headphones: SR-009S Amp: SRM-007Tii, or SRM-D50 Preamp: Integra DHC-40.1 I would like to avoid spending ~$6000 on an amp unless it is truly necessary to maximize the performance of the SR-009S. If I can get 90% of the way there with a more reasonably priced product that would be preferable. Hopefully the 2 options I listed above would be sufficient. I also want to make sure my pre-amp is not a limiting factor. I’m hoping that won’t throttle performance somehow. I believe an advantage of the SRM-D50 amp would be that I could bypass the need for a pre-amp? Not sure, help very much appreciated, I’m leaning toward the SRM-007Tii if the setup above would work. Usage will be for music, movies, games, connecting to a PC and PS4. Thank you in advance for any advice. I apologize for my embarrassing lack of knowledge, and if this is not the right forum for questions like this.
