MHDT Orchid or Lampizator Amber 3?

I bought an adapter to convert to a 6SN7 tube (I used a Sophia Electric) and gave it a brief tryout in my stock Orchid. I couldn't get it out fast enough. Not recommended. Should have listened to grannyring.

I always listen to Bill.....at least in this arena.

Hope to have the WE tube before the weekend, left the Orchid cooking last night on a playlist so will see today what it sounds like, should be just over 30 hours on it by now.

I bought my Orchid second hand here, and it came with an assortment of tubes and DAC chips.  Being already "burned it" it sounded great from the moment I first inserted it in my system.  I haven't tried them all yet.  I have the original chip in and I think at the moment a  WE 396A tube.  It was only $35 for the 6SN7 adapter and I already had the Sophias, so it was a relatively cheap experiment, but the 6SN7 definitely was a change for the worse.

 I have a Mullard CV1988 from Swedish military  which is an OEM Osram metal base B65,will try as soon my adapter arrives.

@denism  Did it sound as if the LTA Z10 had any problem driving the Spatials? Even though they are sensitive, I heard their impedance curve does not do well with lower powered amplifiers.
