It is exciting to become a La Scala owner as I have also recently. I already had some experience with tube amps (100 wpc monoblocks which could use many types of output tubes including KT-88, EL34, 6CA7, 6L6GC, and KT-66, and I tried them all, and a Scott 299 using EL84 output tubes), but had no experience with high efficiency horns. The La Scalas were priced low enough and were available locally, and I was very curious about these classic speakers. I often read about great synergy between Single Ended Triode (SET) amps and horn speakers so when the opportunity to purchase a SET amp using the 845 tubes, it made sense to try the combo. As advocated by another member, switching out the stock K-77s for Crites CT-125 tweeters peeled away a layer of veil and opened up the sound, bringing forth better detail without etch or grain. At the same time, I swapped the AL crossovers for Crites A/4500. As you might know already, high efficiency horn speakers show off every flaw in your upstream equipment. Putting high quality amplifiers and preamps ahead in the chain will really show what the La Scalas are capable of sounding. As wide as their front baffles are, they can still pull a disappearing act and throw a deep and wide soundstage given you take the time to move the speakers inches at a time until you get the result that satisfies you. I am surprised the La Scalas are as picky about their position as they are; at the same time, amazed at the dynamics and smoothness to vocals they create. Do not forego an active preamp. A preamp is the heart and soul of your system. Preamps are more than just a switch box with a volume knob. It is there to extract the most from your records and CDs. As much as "straight wire with gain" sounds pure and almighty, it often leaves music sounding cold and lifeless. Get it wrong here and one spends a long time swapping amps, CD players, and cartridges in and out trying to get music to sound like music. Ok, so you do not have much money and I do not know what your budget is but let's say it's $500 tops. A quick look at used tube integrated amps on Audiogon showed many at that price range and it would be a good place to start. Feel free to email me if you have additional questions. Have fun!
