2 Dual turntables(506-1229) through 2 Cambridge Audio 551P phono pre's to the amp and out to the speakers. My laptop with 44,000 songs through a Musicstreamer2 Dac to the amp. I have my set up as follows with 2 channel. If that doesn't do it for me, then I am going to look for another amp. So I don't know if it's break in with the new tubes or the amp needs to have the bias recallibrated.I'm also looking into 6922, ECC88, 6DJ8, and 6N23P tubes as replacements. The issue there is not enough power for what I want. It does sound different still from SS, but doesn't have the depth the other Chinese amp I have does. The tubes that came with the amp were the Chinese tubes which I switched out to the generic Russian 6N1H version and the new Tung Sol Platinum E元4B's. I'm looking at different tubes for the amp I have now to see how much more I can open up the sound stage. Discussion in 'The Klipsch Korner' started by skarma, Dec 13, 2013. My other question is which tube amp would be best suited for the speakers. I'm assuming they will be a step up, but how much of a step up?
#Klipsch kg 4.2 vs 5.5 upgrade
I have the 4.2's hooked up to a Yaqin MC10L Tube amp for my 2 channel (which I may also upgrade down the line) and if the 5.5's are worth it, will switch them into the 4.2's position. How much difference is going to be in the SQ? Is it going to be only bass response or pretty much everything? Above is a KG1 I bought new (as a pair) in 1990.

However, with the addition of the big boys in front, it made it more difficult for the 520Cs 4' woofers to keep up with the RB-61 IIs 6.5' woofers. It was used on the KG1,KG2,& KG4 grills until 1992 when the KG series were redesigned. After buying the 520C, I bought a pair of Klipsch R-41M for the front channels, and then I bought a pair of Klipsch RB-61 II to use as front channels and moved the R-41M to the rear. There is a set of the 5.5's going for $395.00 near my area and I wanted to see what the major difference in the 5.5 is to the 4.2. Klipsch speakers dating back to the 1950s such as the Klipschorn, LaScala, Cornwall, and Heresy were designed with analog sources in mind. They sound comparable to the 4.2's to me, minus the bass response. I have a pair of KG 3 Signature Series, and a pair of 4.2's that I just upgraded with the Crites crossovers and tweeters.
