    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. I like this graph a lot, but it completely ignores electronic/dance/hiphop etc. music which often goes way lower than 40Hz.
  2. Last night I was switching between my small tubecube amp and my solid state marantz amp, and it must be said that my 3.5wpc Tubecube produces more low frequencies than the Marantz, through the same Heresy speakers.
  3. I used to have a Dual turntable and amplifier as a student. Moved with me as I moved from town to town. Then, one day... I brought it to the dumpster, because the dual amplifier no longer worked (probably a blown fuse). I must have had a total blackout, I guess... What mistake that was... I bought a cheap, plastic JVC 'stereo system'. That was even a bigger mistake. So, here is my 2 cents: once you have your Dual turntable, cherish it and every night, before you go to bed, you give it a sweet little kiss and enjoy the music it produces!
  4. A set of original 1972 Heresy speakers. If I want to play loud, I use my ss Marantz, for quiet listening, tubes.
  5. Here is a really nice article about how much/little wpc we really need, and why. That's why I love my 3.5wpc Tubecube7 so much. https://kenrockwell.com/audio/why-tubes-sound-better.htm
  6. I mostly connect my Amazon hd 8 fire tablet to my amp with a double mini jack cable. I' ve got some flac files on it and they sound pretty good, good enough for me, which is the only frame of reference that matters anyhow...
  7. In my experience, CDs sound better than Spotify Premium... I used to have Qobuz, which allows streaming in high-res, and sounds much better, even in cd-quality streaming. The only reason I migrated to Spotify, was because they have a 'family' formula, on request of my kids... Cannot compare with Tidal.
  8. I'm just wondering: why doesn't anyone suggest Klipsch' own Powergate? Seems like a capable machine, and very affordable? https://www.klipsch.com/products/powergate
  9. If any babies arrive, please let me know... I live in Belgium, not so far away! Something got lost in translation, I think... ;-)) On a more serious note: love your speakers/room. I used to be with Qobuz too, but switched to Spotify Family (for my teenage kids). Qobuz doesn't have a the family formula, do they?
  10. ... All your crossover components fall within specs... So why replacing them, then? They are just fine and will likely be for years to come...
  11. I restored a pair of Heresy Ones recently. All I needed to do was replace the caps and oil the veneer a bit. Total cost was €40, soldering iron included! At age 47, tweeter, squawker and woofer are still in excellent condition. The cost of the Jantzen Cross caps was actually less than the postage cost, €9.95
  12. This is Ken Rockwell's review of the Tubecube 7. https://www.kenrockwell.com/audio/tubedepot/tubecube-7.htm
  13. I know, but I wanted the Tubecube 7...
  14. Yes, I upgraded to EL84M tubes.
  15. I live in Europe and paid substantial postage and import duties for Tubedepot's Tubecube 7, a cd sized tube amplifier. I have no regrets at all, because the sound it produces is amazing. And, though it is only 3.5 W per channel, it can play really loud, especially with my efficient Heresy I speakers. Of course, my Marantz amp (40W) can go much louder, but for my room and listening style, the Tubecube produces more than enough decibels... Hence my question: in plain terms, who can explain the science of this to me? I've read it elsewhere: it is the first couple of watts that are important... But why?
