The speaker is around 96 db sensitivity and can take up to around 100 watts. The price for Hypex class D amp is good but, look at the power ratings. The speaker will never live to see that much power: 350 watts for 8 ohm speaker. I love class D amps witch are very clean. Some people use tube amps with their Heresy speakers. A lot of the tube amps used are SE and less than 12 watts. A class D amp or another type of amp may give you a slightly different sound but, better is in the eye of the beholder.

The person that wrote the review described so many problems, it is obvious they did not have things setup correctly. That's not any amps fault!

I have used avr, class A, AB, digital and tube amps. I have never had a problem paring them with any speaker. I am not a believer of reputable manufacturers making amps, avr or tube amps for specific speakers. Speaker sensitivity and ohm load may be more important when selecting an amp, or avr. If the amp or avr has enough power, it should work.

A subwoofer or two would compliment the Heresy since it's cutoff is around 50 Hz. You have a large room and the bass may be a bit soft with just the Heresy.

You could use either, the RP line are considered better build and may use different drivers. What direction do you want to go? Get the RP line if you plan on a Klipsch system. Either should do the job with some EQ.

What speakers do you currently own?

Carver makes a nice looking tube amp. I used to have an old Carver Cube amp. It worked great. Enjoy!.

I like the ones on the right. I have had RF 7, 7II, RC 64, Forte, all the Icon V series and know first hand there is no giant leap in SQ from one series to the next. I still own the Icon VF 35's since 2011. I got rid of a lot of Klipsch speaker but, kept the the VF 35's. The wanting to upgrade can be costly over the years. Save up and buy your dream speakers and not look back, it's cheaper, lol.

Hum, or hum eliminator. I have used one of these before with success. It's around $30 on Amazon and may be worth a try.

Lateral pass at best. For HT, no discernable difference and not much difference for music. This is even more true for systems with EQ.

I used Klipsch in-wall for surrounds and another band speakers were atmos X4 andthe RC 64 center and RF 7 II's for the front with subs. The processor from the Pioneer Elite did a great job with EQ.

Hmmm... What is running the show. Good AVR and processors can EQ mixed system seamlessly, I had a mixed Klipsch system.

Good high end avr's have discrete amps and can perform as well as most amps of a similar price range. A higher power amp will only benefit if the speaker can't reach the desired SPL . The sensitivity of the Cornwall is over 100 . A speaker of 89 db sensitivity can reach 99 db with just 50 watt. I have heard Cornwall on low power tube amps and sound good. Maybe this amp hunt, won't solve the problem?

I have had many different center channel speakers from Klipsch. As far has the sound, I don't worry about having the exact series speakers. I do try to keep speaker from the same line. With the avr, I can make an RC 62, RC 62 II and the third generation pretty much sound the same. The big money in the avr is for room/speaker EQ. All the talk about timber matching is overblow IMHO.

New speakers might be easier than playing Mr. Fix it, 😁

Connecting playback devices to the system may also make a difference. When playback device are connected to the TV(monitor), it runs the show. When playback devices are connected to the avr(network receiver/HT), the avr runs the show. The point is that the avr can decode more format than the TV. Concerning more power, I have not seen where having excess power improved the sound quality at low or high levels unless the amp is under strain. I use my low watt tube amp sometimes for HT.

I direct mode with the least amount of processing, the sub may not be fully engaged. Direct mode gives me the least amount of bass trading off for improved midrange and Hi's.

I have used an avr and integrated amp with pre-outs for HT and movies. As long as I am in the acceptable power range of the avr and or second amp, thing should pretty much sound the same. The power rating of the avr and power amp are close enough in your system, it should not be noticeable except at high volumes, maybe. How thing are handled depends on the various connections. If I plug everything like the BD, CD, etc. into the TV, things are processed differently compared to connecting the BD, CD, etc. to the receiver. I have use the pre-outs with my 200 watt/channel Acurus amp and my 45 watt tube amps.

Why the Oldchen, ask my 4 y/o grandson, lol. The rest is history. I have previously owned a tub hybrid amp and two EL 34 amps. The previous amps were the Yqin 2100, and the 13S respectively. I like all of the amps but, the hybird amp was to much like SS. The EL 34's were excellent: clear highs, good tight bass and plenty of headroom. It was time to try a 300B or KT88. I only use digital media and wanted a streaming source and HiFi audio. After reading up on both types of amps, I thought the KT 88 would better suit my living space due to the added power over most 300B amps. I have had good luck with my other amps and decided on the Oldchen K3 KT88 BT. It is a push-pull amp capable of 45 watts in class A and can be push up to a round 90 watt. The amp came with Psvane KT 88 X4 and CV 181 tubes. Initial impression was that the amp looked and felt well built. Nice gold binding post with a 4 and 8 ohm connector for the speakers and 3 analog inputs..I replace the stock tubes with Shuguang black treasure CV 181z in the preamp and Shuguang black treasure KT 88z. The KT88 has a nice warm low end and detailed midrange. The Hi's are not has pronounced, or bright compared to my EL 34 amps. Realism describes the presentation with good imaging and crystal clear music. This is a very budget friendly amp that easily qualifies as a good Hi Fi tube amp for home use.

I will pair my Focal Aria 926' for 2 channel listening with the Marantz NR1200 or the tube amp using a Niles DSP1 A/B speaker selector. A simple system.

Yesterday two surprises, Marantz NR 1200 and Oldchen K3 KT88 , 2 channel network receiver and tube amp respectively. They both sound great right out the box.

That's a very nice amp with a great sound.

I have an Oldchen K3 KT88 amp. It uses four Psvane KT 88 tubes in the power stage and the preamp has 6NS7 X 3. If I replace the power tube with another matchd quad set, does the bias need adjusting? The new Shugang Black Treasure KT88 tube has mV 35. The current Psvane tubes are mV 45.

I own the Icon VF 36 HT and loved it. The Icon W and X completed the Icon line. Thee VF series was sold in BB and was considered cheap and not as good as the Reference line. Later I switched to Reference speakers. I still own the Icon VF 35's. I have sold off most of the Reference line due to downsizing. There is no dramatic difference in SQ, people have used earbuds and Ipod and you can make out the music, lol. Speaker tech advances but, not gigantic leaps that the speaker makers use as selling point. You may only need a sub. Hard to get rid of the itch....

The sub should take over at the XO. I use my Pioneer SC 99 with a sub and speakers set to small. The sub works for music and movies. The XO is set to 80.
