    Klipsch Heresy I (1972)
    Klipsch RP160M
    Marantz MP5005
    TubeCube 7 | Tube upgrade: Sovtek 12AX7-LPS (longplates) and Sovtek EL84-M
    Pro-Ject Essential III - George Harrison special edition

    a Amazon Fire 7 for streaming (cable-connected to the switch)
    a brandless cd/dvd player (it also has usb-in and a cardreader)
    Spotify Family

    Sovtek 12AX7-LPS - This is an entirely new design from Sovtek and a great step up in sound quality. They have very large ribbed plates and great sound reproduction. I found them very smooth and well balanced in terms of bass, mids and treble response. The large plates make them more prone to microphonics and in combo amps, so they can be a problem if you like to run things wide open. It is still the best thing Sovtek has produced in a 12AX7, with very good gain and low noise. I would advise against using them in compact high-powered combo amps where they will be subjected to lots of vibration. One other note about the construction of these tubes is they have filaments that are almost completely encased in the plate structure. They often don't "light up" when working properly. This is not a problem, it's normal for the LPS.

    Sovtek EL84-M - A military-spec version of the standard Sovtek EL84 - the Sovtek EL84M's extended voltage tolerance - improved plate dissipation - and rugged construction make it equivalent to the RCA 7189. Chosen by Matchless for their designs - the EL84M also features higher transconductance - more power - and longer life than the less expensive EL84 - making it perfect for hi-end audio applications. However - many musician's prefer the regular EL84's warm distortion to the EL84M's tighter - cleaner tone. For all Hi-Fi users - the EL84M is definitely the tube of choice.

  1. The CWs have a sensitivity of 102dB. You can drive them with a 3.5Watt amp, if you choose to. The CWs are sold with the specific catch-phrase that they deliver excellent bass response, "the best of the best", so why should this new owner invest in a subwoofer? Let's face the facts: the grille is faulty, and we can only guess what else is wrong with this speaker set. What happened at Klipsch Quality Control? My suggestion is that Klipsch Inc should do everything to get this right! And within a week, not in three months time! From Klipsch.com And:
  2. You may be right about that. Spotify is even worse as for user interface.
  3. Don't know where you live, but here in Europe, the Qobuz catalogue is phenomenal in depth. In Europe there is no 'family account', though, and that's the only thing keeping me from joining them again. In the US, the do have a family account (up to 6 members). So this difference may suggest their catalogue is different too.
  4. If I were in the market for a phono stage, I'd buy this one https://www.project-audio.com/en/product/tube-box-s2/
  5. Your cousin is a lucky guy, and tuberolling can be fun indeed. If I ever win the lottery, that CS600X is coming my way! Still, the Leben engineers must have had a specific 'sound identity' in mind (the "Leben-sound" perhaps), or else they would not change the architecture of the CS600 to adapt to the different stock of NOS tubes: The Leben CS600X is replacing the current CS600. As it is now difficult to obtain a good quantity of the 6CS7 valve which is used in a current CS600, Leben was compelled to modify this model to use a different valve. Consequently, a new CS600X is equipped with 12AU7A & 12BH7A instead of 6CS7 tube, thus the main difference of CS600X is that two tubes(12AU7A and 12BH7A) are sharing a job of 6CS7 tube and some modifications have been made to the circuit accordingly. Leben still is holding a limited quantity of 6CS7 valves, so for now they will continued to sell the CS600 and CS600X simultaneously. (source: https://hifipig.com/leben-cs600x-stereo-integrated-valve-amplifier-released/ ) I'm not sure where hifipig.com got this information, because the official Leben website only mentions the CS600, not the CS600X. Maybe the English language website hasn't been updated properly. https://lebenhifi.com/products/cs600.html
  6. Agree! My Denon with Rp160m is nice and warm. However, my new Marantz pm5005 doesn't go well with my vintage Heresys. The HK430 with the Heresys is excellent!
  7. Welcome to the forum! I 've owned the RP160M speakers, which are very similar, for 2 years. They are in my living room. They've gotten even better since I got them. The Echo Link Amp doesn't get very positive reviews sound quality wise. https://www.whathifi.com/reviews/amazon-echo-link-amp The reviewer in the link above may be biassed, though. Still, if you have any other amplifier in the house, you should try it with your new speakers. The RP600Ms are great with vintage solid state amps too. If you are lucky, you can pick one up for little or no money. Or a relative or friend may have one unused. Anyhow, you did a really smart investment and you are looking at many years of musical enjoyment.
  8. Correct me is I'm wrong, but Technics, at the time, had a huge reputation for quality, while now it is a lesser sought after vintage brand. I recently came across a Sierra branded amplifier, at give away price... This one certainly has the looks of quality, don't know how it sounds, though.
  9. Nice build. What does the battery pack do?
  10. Yeah I was so in a hurry to listen... Going to rearrange and 'de-clutter' my audio corner... I have same feeling I had after I bought my analogue camera Eos Canon 1v: after that, I was cured from my 'GAS' (Gear Acquisition Syndrome) for cameras, because nothing could do better than that camera. The HK430 plays in the same league.... 😉
  11. Ode to my newly acquired H/K 430 Please bear with me. I know this anecdotal, and I have read similar stories on this forum but I would like to share it with you anyhow. So in the beginning of the week I bought a H/K 430 on an auction site from a private seller. He had a 100% rating as a buyer, but never had sold anything on the site. So that made me a bit nervous. It arrived on Friday (yesterday). After I contacted the seller to thank him for the excellent transaction, he told me he actually hadn't intended to sell it. He had owned it for a while, unused, and then put it on the auction site. Then he started listening to it. He loved it so much that he decided to restore it, so he had ordered an upgrade kit. That's when I came into the game and bought it and paid for it immediately with Paypal. He then realized he'd forgotten to take it off the auction site. For fear of losing his 100% rating, he reluctantly decided to let it go. So when I got home from work, the H/K 430 was in my carport, packed in a Canon A3 printer carbon box. I couldn't wait to unpack and to start listening. The amp is in pretty mint condition (for a 44 year old) and all the lights are working too. Connected to the 1972 Heresy's, The sound is simply amazing. After I connected an FM-antennae, the vu-meter went up to 7 or 8 for the main stations. At first, I thought the phono stage was just average, but later in the evening, it sounded much better (or my brain had adapted). Now I think it is amazing. Also CDs and my DAC sound pretty amazing. As the hours progressed, the bass tones became even more prominent. But all this, my friends, is just introductory. Late at night, my wife returned home. She was in a terrible state: a very long, tough working day, followed by 3 hours of difficult cello class. She was exhausted. I convinced her to take a seat in my listening rocking chair to have a quick listen to my new amp. Just five minutes. She reluctantly gave in and sat down. I started playing Katie Melua’s “The Closest thing to Crazy”. The wife closed her eyes. ‘Now play “Nine Million Bycicles” please.” Her eyes were still closed. When that song ended, she said: “Now play “Oblivion” (Il Gardellino).’ And she added: “Does it also play any louder.” It was already past midnight. Our 3 teenage kids were already in bed. She: “Turn it up a bit.” Now usually, she would say something like: “Can you turn that damn music down please.” But not tonight! So we ended up browsing through our Spotify playlist until way past 1 o’clock. All stress and exhaustion was wiped off her face. As we were going through the ‘usual suspects’ on my playlist, I had an existentialist experience: it was as if I had never heard them before. Really. Just like that. The more I focussed, the more they sounded completely new to me. Mind you, no alcohol consumption was involved. 😉
  12. Well, today my HK430 was delivered. It is unrestored, in original condition, all is working. First impression: the radio section is amazing, phono stage okay. Will be testing CD and DAC in the course of the night. Perfect combo with my 1972 Heresy speakers. Update: falling in love with the stereo fm all over again... Update 2: the twin power really makes my 1972 Heresy shine in the low frequencies. Update 3: I know it's a cliché, but I 'm hearing new details/aspects in my music.
  13. I read somewhere that tubes that are popular among guitarists are different (warmer?) than the more 'accurate' tubes popular among audiophiles. Still, some say it is the architecture of the amplifier that determines the warm sound, not the tubes. Leben, a famous Japanese audiophile brand, builds their amps around the stock of NOS valves they have on their shelves. For instance, the Leben CS600 is now replaced by the Leben CS600X, which has different tubes. Inside, the architecture has been changed dramatically by the engineers, though the outside of the ampl looked identical. What you are asking is like asking for the 'secret formula' of Audiophile Universe. Many have opnions on this, few are experts. (I know I am not...) https://www.psaudio.com/article/whats-the-warmth-in-tube-amps/ This is what I gather from the artilce: According to the linked article, the warm sound has much to do with the 'darkness', the noise the amp produces. The signal-to-noise ratio is crucial here, for phono stage, and another spec I would look at is the 'total harmonic distortion': some amps have 0.3, while others are 0.03 For hifi, the latter is better, for guitar amps, some will find the 0.3 more interesting. While at first sight, there is little difference between 0.3 and 0.03, but in fact it is huge, and certainly audible, esp with efficient speakers such as Klipsch.
  14. I would go for a recent iPad, with recent OS and security features. Amazon's Kinde Fire tablets are cool too, I bought a dirt cheap Fire 7 tablet several years ago. It still runs Spotify fine.
