In Reply to: RE: Audio Research LS-28 line pre. Just how much better? posted by audioman on April 16, 2017 at 12:43:57
Glad to help.
The REF75SE is a killer amp perhaps the best small wattage amp ARC has ever produced. I have owned two first the original REF75 and the REF75SE since last fall. The difference between the two is not subtle. I encourage anyone that has the REF75 to upgrade to the REF75SE. The changes ARC made in the amp is far more than a switch to KT150 output tubes and new coupling caps. There are improvements in the power supply, input stage, and much more.
The REF75SE will be an excellent match with the LS-27. Depending on your speakers and the rest of your system it may be a better upgrade than the LS-28.
Sometimes new ARC products do turn out to be incremental improvements over what they replaced. The SE upgrades for the current amps and the new preamps, phono stages represent more than just incremental improvements they are a big step forward.

Yes my brother, I have also heard this from a number of dealers who carry the ARC brand. My dealer told me this as well, that the Reference 75SE amplifier has actually
interfered on the interest and potential sale of the 150 and G series amplifiers.
Although I do not have extensive experience with the ARC brand, it has a presentation that is "right for my taste" and their seems to be a level high of consistency from product-to-product. I think it would be a safe statement that the Audio Research products are very well respected throughout the industry on the whole.
Thank you again for your valued input, much appreciated
IME, the Ref5SE pre-amp is the best value, for your money.
Have you compared them or is your assessment based entirely on price? The Ref 6 is clearly more a re-design than a uograde and the reviews have been unanimous that the jump up in sound is remarkable. Though admittedly not a major review mag, the AudioBeat review is by a guy who owns a Ref 5SE
Thanks! for sharing- theaudiobeat.com article.
I've decided I need the Ref6. I believe that once you reach a certain point the preamplifier is the second most important component in the chain-after the source and more important than the choice of speakers. After a certain point of competent design, loudspeakers are flavors and mostly depend upon optimum placement. I believe 95% of loudspeakers in avid audiophile's rooms are placed shy of optimum in their rooms. But without a top-drawer preamp things go awry. I've owned passive and tried "no-preamp". A top preamp sorts out the music and makes it appropriately dynamic. I believe my oresent tubed preamp is competent-a 25 yr old Audio Prism Mantissa-and it's not outdated, but it's time to take a few steps up the ladder.
