MHDT Orchid TUBE ROLLING
I am the person who introduced the idea of using 6922/ecc88 family tubes in mhdt DACs, in the head-fi forum. As stated you need an adapter. I took a flyer on the idea after experimenting with every 5670 compatible variant tube. There were certainl... 
Name 3 classic mini-monitors worth keeping- Why?

No doubt that Druids + Submissions will make the initial impression of being altogether badass. Living with that over time and a full spectrum of music can be another matter. But it depends what drives your perception of convincing musicality. Or ...

Some catchup:Our brainless administration's dumb trade war with China has slowed shipping of my last couple of custom amps. I expected them earlier this month but now it will be sometime in June. Shortly after I get them I will complete my amps su...

Which Whammerdyne? Would you spend the cash for the Parallel Single Ended model? I'm guessing not.I haven't heard the Whammerdyne. And I have only an academic interest in it because a 2a3 SET amp just doesn't have enough shove, even for 101db/w/m ...

Keep in mind, the sub amp is a Class D, with relatively low consumption requirements, and the amp has limited frequency duties in this application. You have far more influential opportunities elsewhere in the system to strive for more objective so...

David,The IsoAcoustics Gaia footers are rated for speaker weight up to 70 lbs per set. Definitions well exceed that, so the isolating compound may not as effective under greater mass.An alternative that is effective for me is from Herbie's Audio L...

Also, by the way, David: To remove your sub amps, note that the Speakon connector there is flange surrounding the connector itself. Start by removing the screws from the Speakon flange. The Speakon connector and its wiring harness stay with the De...

Definition 4 setup uses less toe-in than Def 1.5 and Def 2 in every room where I have heard both. Particularly in a relatively near-field situation.  Both the Radian supertweeter and the FRD have broader dispersion than the respective drivers in t...

David,I was able to speak with Sean Casey this morning. Your Def4s definitely are early enough to have to original lower-gain sub amps. You have s/n 007/008; I have s/n 009/010. You have three options, one of which requires you spend some money.Fi...
