@mike30 the LS27 is a fine preamp. The se versions are exceptional as well. The ref series, end game. If you have to make a financial compromise, buy the best preamp you can afford. It will make every amp better…but the inverse isnt always true. Hanging an amazing amp off of an average preamp doesnt necessarily yield the superior results…
good luck. The 75se can be end game, it is already a classic and it is a really nice amp across a broad spectrum of speakers.
