So I have slowly been getting into this whole audiophile thing the last couple of years (and I am definitely not as hard core as some) and am wondering about getting into the tube amp arena. Currently I am using a Pro-Ject Debut Carbon DC Turntable with Ortofon 2M Red Cartridge turntable with a NAD D3020 V2 (I'm not looking for volume just quality sound) with Klipsch RP-600M speakers in a small (12' x 14') room. I am considering getting a Reissong A10 EL34 tube amp since i have read good reviews on it and for the price doesn't seem to be a horribly expensive investment to dip my toes into the tube arena. So I have two questions: 1. recognizing that listening is subjective (my spouse doesn't hear the difference between different records that i do), is there really a noticeable sound difference with a tube amp? and 2. given my set up, it is my understanding that I will need a phone/pre-amp before the Reissong tube amp so could i use a second Reissong tube amp to act as a pre amp or is there a different recommended pre amp? any advice is appreciated. Thanks.
