  1. I am using Tidal in conjunction with Roon software and it has excellent sound quality. Many of the titles are in 24/96 resolution. If you have MQA decoding it would likely be even better. I am streaming thru an Exasound Playpoint streamer with an Exasound E32 dac.
  2. Thanks everyone for looking but this is now sold
  3. I am selling my small Walnut MAHL V1 tweeter horn I purchased from DaveA. I am selling as I decided to upgrade to the V2 horn. These are in excellent shape. Has been stained with walnut Watco Danish oil. It looks real nice and does sound much better than the K77 driver/horn when using a de120 driver. I am selling for $85 and will include shipping.
  4. Here is how I ended up doing mine. I found a couple of sand filled 2lb wrist weights and placed them on top of the tweeter stand. This was quite noticeable in comparison to having no extra weight.
  5. I have been physically time aligning my Cornwall with Dave’s original walnut tweeter horn and a homemade baffle. I agree with other comments. Once you hear the tweeter physically aligned with the midrange you would not want to go back. The mid point of my tweeter is 5” from the top of the cabinet. It is important to absorb reflections off the top of the cabinet. I bought a 12 x12 absorption panel from guitar center and cut in half to place in front of the tweeter to absorb the reflections. I also needed to add some weight to the baffle to get the best sound. Possibly this new tweeter horn would have enough weight to not have to do this but adding some weight to the top of this would be easy.
  6. Not sure how that would work. If you glue one end of a 2x4 i would think the weight would not support it until you got the rear panel in place to secure with screws. Maybe i am not thinking this right. I have also heard that others have added a 3/4” panel to the back of the existing panel to keep the back panel from flexing. Am curious what results that may bring.
  7. Last weekend I decided to try bracing the motorboard on my Cornwall 1. I had seen an old post regarding this. I put an 18" 3/4 X 1 3/4 piece of oak half way between the mid horn and the woofer and secured with 5 screws. This rather simple bracing made a huge difference eliminating any of the boominess I had as well as improving the midrange clarity. I was concerned about taking up cabinet volume but this takes up very little. Have many others tried this?
  8. I heard the new Cornwall lV’s at RMAF today. I was somewhat skeptical going in but I must say they sound fantastic. Really great midrange resolution and very tight controlled bass. I have modded my Cornwall 1’s and they are sounding really good to me but the new cornwalls are definitely a step up.
  9. The input tubes are 6J4. I do think this is a variation of his Darling circuit. The 3-4 watts is probably right. I would do ups ground shipping for $25.
  10. Thanks but not interested in a trade. Just need to move out some of my stuff.
  11. I picked this up a few years ago as a backup amp. I have used this amp with my Cornwalls and it really sounds good with surprising control of the bass for such a small amp. This is one of Jeff Larson's earlier builds .The guy I bought it from had for around 15 years. The output tube is a rather uncommon 1626 tube. They are readily available on ebay etc and are not expensive. It will come with a new set I recently installed. I believe that the amp puts out 4-5 watts and is a great fit for Klipsch speakers. It does have a volume control so can be used with one source without a preamp. Price is $275 plus shipping cost.
  12. I replaced the k55v (not dual phase plug) with the A55G in my Cornwall and IMHO was a significant improvement at a relatively modest price. I hear much more resolution and less distortion than with the k55v. Matching that up with the DE120 tweeter in my opinion really takes this sound to a new level.
  13. Dave Brubeck Time Out, Chet Atkins in Hollywood, Dire Straits Brothers in Arms, Kenny Burrell Midnight Blue
  14. I used some 3/8" rubber window seal from Home Depot to seal the backs of my Cornwalls. Only costs and there was a definite improvement in sound after installing.
