Deciding To Build Either SEX 2.1 or Foreplay3

post #1 of 4
Thread Starter 

Wondering if anyone has built either one and can comment on them, im looking to add a bit of tube sound to my rig. I got a buffalo, beta 22. Im wondering if getting a pre-amp or another headphone amp is a better choice. If I get the SEX I can choose to listen to tubes or ss. If i go with preamp then maybe together (beta+foreplay3) they will bring more out of my headphones (mainly K1000).

so get the foreplay over the sex, is there a specific reason just wanted to know the logic behind it since I cannot decide. Unless you are being cleaver on the wording of the statement, either way lol.

I would suggest the Foreplay first...

I use the Extended Foreplay III more as a variable voltage or gain connecting box so I don't have to switch wires to use either of my 3 headphone amps.  Its been said that using a preamp before an amp with a volume control is degrading the sound and I would be better off taking the Goldpoints out of the Beta 22 & Bijou and use the Foreplay to control the volume.  Makes sense but as I have now it sounds OK to me and the Foreplay only has 11 steps with the Sweet Whispers.
  The 3 headphone amps have different gains and the 4 headphones have different Ohm levels so, for example, I use the Foreplay to to make the input voltage hotter or colder on the Beta 22 (2X gain) when each headphone is used.  I built the Beta 22 to match perfectly with the 25 Ohm Denon 7000's but it don't go loud enough with the STAX SRD-7 SB transformer box, the SEX 2.1 amp will be used for this purpose when Bottlehead has the trans switching board for sale or I rewire).   I "feed" it more from the Foreplay and that decreases the travel of the volume control on the B22 and I turn it up so the STAX 'phones are at the loudness I like.  I adjust the Foreplay to suit my other amps likewise so the volume is at 12 o'clock or so with whatever 'phones I use.
