Is 5 Watts enough for Horns ?

Lonestarblues: no doubt, 3,5W sound OK on yr COrnwalls. BUT, try 20W capability and listen to orchestral music -- and I think you'll be surprised.

You've modded those Cornwalls I assume (nice spkrs)?

my buddy is using a 6 watt chip amp (forgot name of that amp) on his Omega DUOs and even in his small room I hear this thing sounds strained and clips quite fast.
I'm using a tact digital amp which putts out around 75 watts into the DUOs 16 ohm impedance and I love the headroom.
Sure I won't ever use all the watts but a more powerful amp is much more at ease when the going get tough compared to a 6 watts amp. JUST IMHO of course.

Hello Gregm. I have 4 systems-2 SETs & SS/tube hybrid amp with tube preamp & Mcintosh SS. I am a Klipsch Heritage speaker fan. I have liked the Heritage speakers since I was a teenager and could not afford them. All Ears a stero shop when I was young carried Klipsch Heritage, Advent & EPI/Epicure speakers. I bought one pair of walnut Advent 1's in 1979 & walnut New Advents back in 1980. The Advent 1's have the same drivers as the New Advent in a slighly smaller cabinet.

You can pick up used Klipsch Heritage speakers for not a lot of money. Change out the crossover network with a new upgraded crossover using the caps of your choice and have a high performance horn loaded speaker with excellent sonics to my ears. Klipsch Heritage speakers are not everyone's sonic cup of tea. But I like them very much.

Welborne Labs Moondogs & Welborne Labs Reveille 6SN7 tube preamp, 1981 Klipsch Cornwalls-with Deang type B crossovers using Auricaps. Deang a Klipsch Forum member makes & sells brand new upgraded crossovers-all parts are new. He sells them here on Audiogon. He is a great guy. The upgraded crossovers raise Klipsch Heritage speakers sonic performance to a much higher level than the old stock networks. I highly recommend them to anyone that owns Klipsch speakers.

deHavilland Aries SET 845 amps-25 watts x 2, deHavilland Verve 6SN7 tube preamp, 1983 Klipsch Cornwalls with Deang type B upgraded crossovers using aluminum Jensen PIO caps. The guy I bought the deHavilland gear from had the faceplates of the mono amps & preamp goldplated at a plating shop. He had an oversized volume knob machined at a machine shop. The volume knob & source selector
knob are also gold plated. As we say in Texas- they sure are purdy.

Llano Phoenix CAS 300/VA2 mosfet/tube hybrid amp-
300 watts x 2. The VA2 voltage section uses 6SN7,
6SL7 & 12SN7 tubes. Currently using a pair of RCA
12SX7 GT tubes. George Wright AU1000 12BH7 tube preamp with tone controls. 1989 Klipsch birch industrial LaScalas with Deang type AA upgraded crossovers using aluminum Jensen PIO caps.

Mcintosh MC7150 SS autoformer amp-150 watts x 2, Mcintosh C38 preamp, 1979 Advent 1's & 1980 Henry Kloss New Advents stacked with the top Advent 1's inverted.

The Mcintosh gear was bought used from two different Chicago area stereo dealers-my first purchase of separates. I have picked up the rest of the gear used from here on Audiogon. Audiogon has been very very good to me!

The guy I bought the deHavilland gear from had the faceplates of the mono amps & preamp goldplated at a plating shop. He had an oversized volume knob machined at a machine shop. The volume knob & source selector
knob are also gold plated

Now that's what anyone'd call a serious hobbyist!

Old Klipsch speakers had good quality Alnico drivers in them -- until the price of cobalt (or was it magnesium) shot up sky-hi.

The best amp I heard on the Avantgardes was a 1.56 watt 45 tube amp from Exemplar Audio. I think that a 300B SET would certainly be powerful enough. I presently have 93 db efficient speakers and 300B amps are not enough.
