Define expensive, please? What could be expensive for you, could be OK or cheap for me. I own a Matrix Audio X-SABRE 3 ($3000) and a Matrix Audio element i2 ($1500). For most of the crowd, they are extremely expensive, for me no. I own a Topping A90D, great headphone amp which also could work as pre amp. A few weeks ago decided to purchase a Benchmark HPA4 to use as pre amp. Yes, $3500 vs $599 but I found I LOVE the HPA4 and now the A90D is for sale. Most people uncomfortable or criticizing the X2, done it based in price vs performance comparing it to most of the popular, less expensive choices. But guess what, there are other guys here in ASR that care more about reliability, customer support, and why not, build quality over price. I'm don't make ton of money but I always make sure the equipment I purchase have good resale value as well. So you see, there are always two sides of the coin no matter what.
