"....price wise one cannot compare the LA 300 to the Jeff Rowland "
Its not exactly true statement. I paid for my Capri quite a bit and Joule-Electra have many promotions.
At worst, instead of LA-300 you can get LA-150 SE as Coxhous did and you will have 85% and half price of "300". Even entry level LA-150 Mk2 will bring you to increadible musical involving level of listening to music. These preamps do not need much attention, 24/7 are warmed-up, you need re-tubing once in 5-10 years, highly relaiable etc.
